DENDROBIUM AUREUJI (HETEEOCARPUM) 



We have in this orchid a native of India, Nepaul, 

 Ceylon, and Java, a very distinct and beautiful species, 

 flowering in late aiTtumn and onwards till March. The 

 flowers appear after the leaves have dropped, and in 

 short racemes of two and three flowers. These are yel- 

 low streaked with crimson lines, and they endure for 

 several weeks in good condition, and are endowed with 

 the fragrance of the violet. The plant succeeds under 

 the same conditions of warmth as D. nobile ; and in a 

 mixture of polypodium roots one part and sphagnum one 

 part, with abundance of clean crocks. A moderate 

 amount of moisture must be ailorded in the season of 

 growth, and scarcely any in the resting season, other- 

 wise its flowering will be irregular. Although flowering 

 whilst in the leafless state, it is a plant worthy of any- 

 one's cultivation, if for its delicious fragrance alone. 

 The flowers difller in their ground tint, and size. 



HONESTY (lUNAEIA BIENNIS) 



In the early days of spring bedding, when Cliveden 

 under Fleming was at the height of its beauty, and Bel- 

 voir, with W. Ingram as gardener, was renowned for a 

 free-natural style of bedding-out with hardy subjects, 

 setting examples — both of them, to the halting garden- 

 ers of Great Britain in the new mode of replacing the 

 bare beds in the flower garden of that time — in the late 

 50's and early 60's, Lunaria biennis was recommended, 

 and frequently planted. Since that day, other varieties 

 have been raised and distributed. I may mention L. 

 biennis alba, L. b. purpurea, L. b. rediviva, and the 

 creeping variety L. b. corcyrensis, which has flowers of 

 almost a blue tint. It might be classed as a species see- 

 ing that the plant is so different to L. biennis of gardens. 

 The flowering season lasts from March to May ; and the 

 plant is a native of the hilly districts of Corfu, and 

 proljably other islands of the Ionian archipelago, but 

 Eowliere else in the world. Under the trees on the bare 

 soil and stony places, where nothing else will grow or 

 l)loom, the plant covers the ground with its innumerable 

 blue flowers. 



INTERNATIONAL EXHIBITION OF BULBS AT HAARLEM 



The first Jubilee Floral Exhibition of the Dutch Bulb 

 Growers Society was opened on March 23 by H. E. H. 

 tJie Prince of the Netherlands. This formed part of a 

 permanent exhibition of bulbs planted in the open 

 ground for the purpose of which an extensive area, south 

 of the town was fenced ofE; and beside this there were 

 four special shows arranged for in temporary buildings. 

 The first of these exhibitions under cover was opened 

 on March 23, and remained open to the public until the 



.^(Ist. This, disjilay con.'^isted for tlic major |)ari of 

 hyacinths, tulips, azaleas, lilacs, and rhododendrons asso- 

 ciated with Primula obeonica, cinerarias and callas. 

 The ground round about the Colonial Museum at one 

 time a royal palace, and in the front of the chief tem- 

 porary erection was planted with crocuses, relieved as 

 regarded its uniform flatness by sunken grass panels 

 and topiary objects in Buxus towards the margins. This 

 scheme of gardening will be kept bright with fresh plants 

 till May 29, when the exhibition closes. An avenue of 

 trees a quarter of a mile long, extends until a pretty 

 pavillion holding a collection of modern flower paintings 

 many of them being the works of the famous Haarlem 

 artist, A. L. Kosher, is reached. Beds of hyacinths and 

 tulips almost cover the ground under the trees; but at 

 the time of writing the only color afforded came from 

 scillas, crocuses and chionodoxas. 



Messrs. C. B. van Nes & Son showed among rhododen- 

 drons a lovely blush variety — Princess Juliana, having 

 a waved edge; it is a cross between a variety of R. 

 hybridum and E. Grifflthianum. M. Koster & Son 

 showed a novelt)', a hybrid Azalea with fragrant flowers 

 (A. occidentalis x A. sinensis). The flowers expand of 

 a lemon yellow tint, and become white with age. Hybrid 

 freesias came from C. G. van Tubergen ; Le Reve, in deep 

 mauve; Dainty, pink with a white stripe; Luminosa, 

 clear rose ; and Eobinetti, pink, were the better ones. Iris 

 lazica, not unlike stylosa, but hardy was flowering for 

 the first time. It is a Caucasian species. Some good or 

 new tulips (single) were General de Wet, an orange 

 sport from Prince of Austria; Eose d'Holland white 

 with an edge of pink; President Taft, white or rosy 

 edge, and two Darwin tulips, one with rosy pink petals 

 and blush edge, and the other a deep pink edge. Mr. 

 Vander Hoef is a pale double yellow tulip; Electra is 

 bright crimson; and Courowne Royal is a bright yellow 

 flower. 



MISCELLANEOUS 



According to Herr L. Dittmann, in a communication 

 in Die Gartenwelt, Eichardia (Calla) Elliottiana may be 

 raised readily from seed but it will be the third year 

 after sowing before any of the tubers will attain flower- 

 ing size and strength. 



H. Burnett .showed his new carnation E. F. Felton. 

 at the March 23 meeting of the Royal Horticultural 

 Society. It is a large, wide petalled flower, rich pink in 

 color but so full that the blooms need an India rubber 

 band to confine them. 



Mrs. Eugene O'SuUivan will discourse on "French 

 Gardening" at the congress to be held for women on 

 July 5 at the Japanese-British Exhibition.
