Notes on Orchids. 



Orchid Seedlings. 



Seedling cypripediums that were repotted in spring will again require attention 

 in the same direction, for much heat and moisture has caused the small amount of 

 compost in the tiny pots to perish, so that fresh compost is very important ; allow 

 plenty of fresh green sphagnum, broken crocks, and charcoal. The seedlings 

 require every care and attention, especially frequent pottings when in a growing 

 state. The same may be said of cattleya seedlings. Dendrobium seedlings must 

 not be interfered with unless the first small bulb is made, then they can be repotted 

 into larger pots. All seedlings ought to be kept growing at a good pace, other- 

 wise the rate of progression is exceptionally slow. A watchful eye must be kept 

 for pests. Cattleya seedlings, growing on surface soil in the pots where they were 

 sown, are now forming small leaves, and will require close watching as regards 

 watering ; keep them in a moderately moist state. These must be well shaded, 

 otherwise the sun will destroy them and dry up the moisture they require.—

Dendrobium Pierardi. 



This is a most interesting and beautiful dendrobium, its great interest being in 

 its being probably the first species of a now well-known genus of orchids to be 

 introduced to cultivation in Europe. It flowered at Liverpool in 1821/and was 

 probably in cultivation at Kew even earlier than that. The species has a wide 

 distribution, and is common throughout North- East India and southwards to 

 British Burmah. It is a plant that is found at home in the mangrove swamps.

cognised by the hybridist, and the only garden SJ^ bCCn re " 

 tion were varieties that evidently originated as cha m Cultiva - 

 sports. Nor is this surprising, for prior to the vear i88? C fL Seedlln ^ s <* 

 varieties in cultivation differed so little in thef priSa UhT°* and 

 as to afford but little scope for the creation ofdiffi^ 15 ^ 

 introduction of the small-leaved mock orange the hybridist ■! e 

 command a quite new type, and Mons. Lemoine, who has awl* 

 to enrich our garden flora, was not slow to take advance of thl much 

 tunity thus afforded for the display of his ripe judgmenf and rareS' 

 He almost immediately commenced the hybridisation of the Mexir .- 



coronarius, and thp r» 



sult was the beautiful hybrid P. Lemomei, in which the characteristic/^ 



we have the dm 

 habit, the star-like flowers, and the floral profusion of P 



phyllus, with a more robust habit and larger leaves, and flowers indi 

 eating the influence of the stronger growing P. coronarius Ttts 

 fine hybrid quickly obtained recognition from those who appreciate hard 

 shrubs with beautiful flowers, and it has been largely planted in British 

 gardens. More recently an erect growing form has been introduced 

 under the name of P. Lemomei erectus, and this is so free in bloominf 

 as to justify the anticipation that it will become immensely popular both 

 for the shrubbery border, and the conservatory, its neat habit rendering 

 it of much value for pot culture. This was well shown by Messrs. Ban 

 and Sons at the first of the two meetings held by the Royal Horticultural 

 Society in July last. 



Having obtained such an excellent result from the first cross M. 

 Lemoine proceeded to intercross P. Lemoinei with various forms of 1\ 

 coronarius, and achieved a degree of success not less gratifying, l v 

 the fertilisation of the former with the pollen of the latter, M. Lemoine 

 obtained, among others, Gerbe de Neige and Boule d'Argent, whicl 

 have single and double flowers respectively, these in each case being 

 pure white, and pleasantly fragrant. Each of these varieties more closely 

 approach in general character the pollen parents than did P, Lemoinei, 

 but the influence of its pollen is seen in the smaller leafage and in the 

 more elegant poising of the flowers on the slender growths. Both were 

 figured in the Gardeners 7 Magazine of August 24, 1895, with an 



accompanying note by Mr. George Nicholson, in which some interesting 

 particulars of their origin are given. Since their introduction to our gar- 

 dens another surprisingly beautiful hybrid has been presented to public 

 notice under the designation of P. coronarius Mont Blanc, and of this 

 we give a characteristic full page illustration herewith. This was raised 

 from P. coronarius fertilised with the pollen of P. Lemoinei or one of its 

 descendants ; and there can be no doubt as to its being one of the most 

 valuable of the several garden forms that have originated with Mom 

 Lemoine. Mont Blanc is wondrously free in blooming, and the flowers 

 are remarkable for their purity, in this respect closely resembling the 

 snow that forms the perpetual covering of the mighty mountain to which 

 it has been dedicated by the raiser. 



Our illustration has been prepared from a specimen kindly supplied 

 by Messrs. James Veitch and Sons, of Chelsea, by whom the variety was 

 admirably exhibited at the second of the two meetings held by the 

 Royal Horticultural Society in June last, when it attracted mud 

 attention. 



• Insect Enemies.— Greater enemies to man than either kids 



mammals are the swarms of insects that, from time to time, commit suchoww 

 upon human food. Perhaps the most historic of these marauders is the '<*™| 

 creature that still does its full share of damage. In South Africa / h ^. lar ?l2£Z 

 locust pass over portions of the country in a broad torrent. Nothing 

 observes a writer in the Standard, their march, for they will till up caw* ^ 

 streams, and even the deep trenches that are sometimes dug in their w . 

 thunderstorm, however, seems to deprive them of their vitality, ine 

 ceases to progress ; and those behind come up to it, and are too ^ 

 over their companions, so that at last a continuous bank of the deaa ^ 

 four feet in height, is formed across the country. America, ^fjw^ay 

 fortune in such cases, has suffered very severely from insect P£*£J"3 pftt 

 and the Colorado beetle being amongst them. The Hessian a Y™™p Ctttm m
