THE GARDENERS' 



CHRONICLE. 



125 



March, shallow drills were drawn along the 

 trenched land, the soil being drawn up on the 

 cold side for shelter. The groups were put out 

 whole, generally with a trowel, and five Pea 

 plants were allowed to each group. The groups 

 were from 14 inches to 15 inches apart. Moder- 

 ate quantities of cow manure were used, and 

 lime and phosphates, with burnt earth were 

 always given. My practice was to provide the 

 Peas with sticks at the time of planting. My 

 Sweet Peas were always the talk of the dis- 

 tricts in which they were grown. " Stripe " 

 did occasionally appear, even as long ago 

 as 22 years, both in the flowers and haulm. 

 For many years I tried to get to the bottom of 

 this trouble both in my own Peas and in scores 

 of others sent me over a period of 10 years or 

 so. Thielavia has sometimes been found to be 

 present, sometimes Fusarium, and occasionally an 

 Alternaria, with Macrosporium among it. I 

 have often thought that the Alternaria was part 

 and parcel of the Macrosporium. In the ma- 

 jority of cases, however, both on flowers and 

 plants, Botrytis cinerea developed, and I 

 have no hesitation in saying that, from the 

 seedling 2 inches high up to the plant in full 

 bloom, for every one plant destroyed by the other 

 diseases named by W., there arelO destroyed by 

 Botrytis. Eelworm seems to help on the destruc- 

 tive work greatly, and will often be found de- 

 stroying the nitrogen nodules and reducing the 

 Pea itself to a pulp. When striped blooms pro- 

 duce only Botrytis cinerea, one is bound to come 

 to the conclusion that the fungus does cause 

 "stripe." Macrosporium is found on unhealthy 

 P Ia " ts , of man y kinds, and it is no unusual thing 

 t« fi"d Cladosporium herbarum, Fusarium sp., 

 and Macrosporium all together on yellowing Hop 

 leaves that have eelworm at the roots. I have 

 also found all the pests on .Marigolds that 

 were railing, the eelworm at the root and the 

 three fungous diseases on the discoloured leaves. 

 I believe that Thielavia, Fusarium, Macrosporium 

 or Alternaria can and do cause stripe. Macro- 

 sporium has, however, appeared less often in 

 striped plants than any of the others, so far as 

 my experience goes. I should place the diseases 

 in the order named : Botrytis, Fusarium, Thie- 

 lavia, Macrosporium, or Alternaria. I have 

 always used permanganate of potash largely for 

 watering Sweet Peas, for stripe in Tomatos and 

 tor sprinkling over the floors of Orchid houses, 

 and I am sure with advantage. This matter calls 

 for investigation by a National Horticultural In- 

 stitute, such as recommended on p. 72, where 

 all such problems could be investigated fully, and 

 where the points could be settled by a committee 

 ot experts. Because one man has found Macro- 

 sporium dunne the last summer on dead Sweet

SOCIETIE 



ROYAL HORTICULTURAL. 



m February 20.— There was a splendid exhibi- 

 tion at the fortnightly meeting of the Society 

 held on Tuesday last in the Society's Hall, Vin- 

 cent Square, Westminster. The weather was 

 fine and very mild, which probably accounted 

 for the large attendance of visitors. Exhibits 

 of Orchids were astonishingly fine for a winter 

 show, and a Gold Medal was awarded to Sir 

 George Holford for a miscellaneous collection 

 of these beautiful flowers. There were, as usual, 

 numerous novelties presented to the Orchid 

 Committee, and this body recommended three 

 Awards of Merit. 



In the floral section, a group of Carnations 

 and Roses shown by Mr. W. E. Wallace, Eaton 

 Bray, was awarded a Gold Medal, the method 

 of displaying the flowers being an object-lesson 

 in good staging. Other important exhibits in 

 this section were groups of Carnations, forced 

 flowering shrubs, Cyclamens, Ferns, Zonal 

 Pelargoniums, and hardy border flowers. The 

 Floral Committee gave an Award of Merit for 

 a new species of Ribes and a variety of Carnation 

 respectively. 



The Fruit and Vegetable Committee granted 

 an Award of Merit to a new Apple. 



At the 3 o'clock meeting of the Fellows, a 

 lecture on "New Sweet Peas" was delivered 



Will

Mr. L. R. Russell, Richmond, put up a 

 showy group of forced flowering shrubs, such as 

 Wistaria, Lilac, Primus lobata, Jasminum 

 primulinum, Cerasus Itisahusa (a glorious 

 Japanese Cherry), Azaleas in great assortment, 

 and Magnolias. Along the edge were well- 

 bloomed plants of Franciscea floribunda and 

 Primulas. Kennedya monophylla, with violet- 

 purple, Pea-shaped blooms, was noticed in the 

 collection of shrubs. (Silver-gilt Banksian 

 Medal.) 



A small exhibit of forced shrubs was also 

 staged by Messrs. R. & G. Cuthbert, South- 

 gate. 



Messrs. H. Cannell & Sons, Swanley, Kent, 

 showed ^ Zonal Pelargoniums, greenhouse 

 Cinerarias, and Cyclamens. The bunches of 

 Pelargonium flowers made a very striking ex- 

 hibit, notable varieties being New York (scar- 

 let), Sir T. Hanbury (crimson), Maxime Kova- 

 lesky (orange-salmon), Snowdrop (white), Hi- 

 bernian (red), and Clevedon (orange). The 

 Cyclamens were flowering abundantly. (Bronze 

 Flora Medal.) 



Messrs. H. B. May & Sons, The Nurseries, 

 Upper Edmonton, showed epiphytal Ferns, hav- 

 ing fine plants of Polypodium vaccinifolium, P. 

 v. album, P. piloselloides, P. p. minus, Dry- 

 moglossum spathulatum, Davallia heterophylla, 

 Drynaria quercifolium, Niphobolus rupestris, and 

 others. (Silver Flora Medal.) 



Messrs. Sutton & Sons, Reading, showed 

 batches of their choice strains of Primulas, with 

 a central bank formed of their Giant White 

 Cyclamen. All the plants were admirably 

 grown, being compact, well-bloomed specimens 

 of the large-flowered type. (Silver Flora Medal.) 



Messrs. Geo. Mount & Son, Canterbury, 

 again showed fine blooms of the rich red Rose 

 Richmond. 



Messrs. Stuart Low & Co., Bush Hill Park, 

 Enfield, showed choice Carnations, the varieties 

 White Wonder, Gloriosa, Fairmount (an im- 

 proved Mikado), and Baroness de Brienen being 

 exceptionally good. This firm also exhibited 

 pans of Cyclamens, including their varieties Sal- 

 mon King and Mrs. Buckston (salmon). They 

 also showed Daphne odora (indica), Boronias, 

 Indian Azaleas and Acacias. (Silver Flora 

 Medal.) 



Messrs. James Veitch & Sons, Ltd., King's 

 Road, Chelsea, staged an assortment of green- 

 house flowering plants, and, as a separate group, 



a number of forced shrubs. Of these latter 

 plants, specimens of the double-flowered, rose- 

 coloured Almond were deserving of praise. 

 At the opposite end of this group were equally 

 fine plants of Wistaria sinensis, whilst Rhododen- 

 dron indicum (Indian Azalea*) figured largely in 

 both collections. (Silver Flora Medal.) 



Messrs. W. Cutbush & Son, Highgate, showed 

 great numbers of forced shrubs, presenting a 

 wealth of showy blossoms; ako a rock-garden 

 planted with seasonable subjects and a collection 

 of Carnations. The rock-garden contained splen- 

 did plants in flower of Iris Sindjarensis, I. reti- 

 culata, Hepaticas in variety, Anemone blanda 

 var Ingramii and Daphne japonica. The most 

 conspicuous of the Carnations was the new 

 variety Lady Meyer, which received an Award 

 of Merit. Other choice sorts were Mrs. Lucy 

 Mackinnon (scarlet, scented), Countess of Lathom 

 (rich crimson), Beacon (scarlet), Britannia and 

 Lord Rothschild (crimson, clove-scented). (Silver 

 Flora Medal.) 



Mr. W. E. Wallace, Eaton Bray, put up a 

 magnificent group of Carnations and a few Roses 

 of the Richmond variety. The varieties of Car- 

 nations were those most popular for market pur- 

 poses, a selection of the finer sorts being Mar- 

 mion, Lady Audley Nield, Carola, Gloriosa, and 

 Pink Delight. ^ The blooms were arranged in 

 large bunches in vases and epergnes with over- 

 hanging arches of greenei v, there being in all 

 2,400 Carnations and 160 Roses. (Gold Medal.) 



Mr. H. Burnett, Guernsey, again presented a 

 fine group of perpetual-blooming Carnations in 

 numerous varieties. (Silver Flora Medal.) 



Messrs. Allwood Bros., Wivelsfield Nursery, 



Haywards Heath, showed varieties of Carnations, 



having good blooms of Lady Alington, White 



Wonder, R. F. Felton, and other well-known 

 sorts. 



Mr. C. Engelmann, Saffron Walden, Essex,

 coloured variety). (Silver Banksian Medal.) 



Mr. G. Reuthe, Keston, Kent, had an inter- 

 esting collection of Alpines and hardy flowers 

 against a background of uncommon shrubs. The 

 rare Crocus Tomasinianus (with silvery-blue 

 flowers), Saxifraga Burseriana tridentata (with 

 large, white blossoms), S. Fernandii-Coburgii 

 (yellow), S. Frederici-Augustii, and Androsace 

 pyrenaica are some of the more interesting plants 

 amongst the Alpines, whilst Berberis Aqui- 

 folium Bealii, with its fragrant, yellow blossom, 

 was a conspicuous plant amongst the shrubs. 

 (Silver Banksian Medal.) 



Messrs. R. Wallace & Co., Colchester, showed 

 early-flowering hardy plants. In the centre of 

 the group was a fine batch of Fritillaria im- 

 peralis chitralensis, some of the umbels bearing 

 four of the rich, yellow blooms. Other plants 

 of interest were Crocus Tomasinianus, C. aureus, 

 C. Imperati, Tulipa Fosteriana, and T. Clusiana. 

 (Silver Banksian Medal.) 



Mr. Maurice Prichard, Christchurch, Hamp- 

 shire, exhibited a collection of Alpines, includ- 

 ing the charming Daphne Genkwa, having 

 flowers of a Wistaria-blue colour. There were 

 also excellent plants in flower of Pulmonaria 

 angustifolia aurea, Anemone blanda, Saxifraga 

 oppositifolia, S. apiculata, S. a. alba, and 

 Houstonia serpyllifolia, a tiny plant, with pale- 

 blue, star-shaped blossoms.

 Snowdrops, Scillas, Anemone blanda, and other 

 early-flowering plants. 



Messrs. G. & A. Clark, Ltd., The Nurseries, 

 Dover, arranged a rockery planted with early 

 flowers and shrubs, the latter including two 

 dwarf, glaucous Conifers, of very attractive ap- 

 pearance, both varieties of Juniperus pachy- 

 phlsea named elegantissima and conspicua re- 

 spectively. Ardisia crenulata was shown in 

 fruit. 



Messrs. John Peed & Son, West Norwood, 



staged Alpines in 



pots, the 



groups being
