SELECTING ORCHID SEEDLINGS. 



If in former times seedling orchids 

 were few and far between, their 

 presence was a continued source of 

 pleasure to the owner as well as won- 

 derment to the visitor. But the diffi- 

 culties experienced in the past have 

 given place to results of so satisfac- 

 tory a nature that in the words of a 

 well known raiser success now smiles 

 upon us. 



The amount of success that comes 

 to an individual engaged in the inter- 

 esting work of seed-raising is judged 

 according to the number of seedlings 

 he requires. Thus an amateur may 

 justly be pleased with 100 seedlings 

 from some particular seed-pod, and if 

 from these he succeeds in growing on 

 and flowering fifty then satisfaction 

 is obtained. But a trade grower with 

 his exhibition needs and wide circle 

 of customers would more likely re- 

 quire T.OOO seedlings, of which 750 

 might well be expected to ultimately 

 reach the flowering stage. 



It is common knowledge that some 

 genera are morn easily raised than 

 others, and, further, that certain spe- 

 cies are particularly vigorous and 



liroduce seed which germinates rapid- 

 ly and in such immense quantities 

 tiiat only a small proportion of the 

 tiny seedlings are pricked off for fu- 

 ture requirements. Whether it be the 

 amateur who wants but fifty or the 

 trade grower who desires ten or twen- 

 ty times the number, each class of 

 raiser, in order to keep within the 

 limits of his stage accommodation, 

 generally finds it necessary to select 

 the number he requires and to discard 

 the remainder, which in some seed- 

 pans will amount to thousands and 

 even tens of thousands. 



The question of deciding which 

 seedlings to select and which to dis- 

 card is one of great importance, far 

 more so than it may on first thoughts 

 appear to amateurs. Consider the 

 Sophronitis hybrids, in which the in- 

 tention of the hybridist was to produce 

 large flowers of scarlet color, and 

 with what results, the seedlings vary 

 in size as much as the flowers do in 

 color. One fact, however, always 

 comes out prominently in the general 

 results— when the seedlings resem- 

 ble the habit of the Sophronitis parent 

 then do the flowers show the great- 

 est tendency to inherit the required 

 scarlet color; the seedlings which 

 grow the strongest and most closely 

 resemble the other parent are fairly 

 certain to yield the largest flowers, 

 but they do not carry forward the re- 

 quired color. Hence it is readily seen 

 that in selecting for future cultivation 

 the seedlings from a Sophronitis cross 

 it is necessary to pick out not the 

 strongest or largest in size, but those 

 which most closely resemble the habit 

 of the Sophronitis parent. 



There are several strong distinguish- 

 ing points which serve as guides to 

 the selection of certain characters. 

 Mention may be made of the long 

 bulbs of Laelia cinnabarina, L. harpo- 

 phylla, Cattleya intermedia and C. 

 Loddigesii; also of the shorter bulbs, 

 as seen in C. labiata and others of its 

 section. Then there is the difference 

 in the foliage, some species bearing 

 but a single leaf, while others carry 

 two and sometimes three. Three char- 

 acteristics are nearly all visible in the 

 early stages of the seedling's existence 

 and the seed-raiser is thus considerably 

 assisted in distinguishing and prick- 

 ing out the very seedlings which will 

 In the majority of cases produce the 

 anticipated qualities in their flowers. 



It is the custom among certain rais- 

 ers to prick-off the required number 

 of seedlings from any particular sow- 

 ing as soon as they are large enough 

 to be conveniently handled; the re- 

 mainder are then thrown away. This 

 method has much to commend itself 

 as regards selecting vigorous plants, 

 that is, seedlings which will rapidly 

 reach the flowering stage and also 

 l)rove suitable for amateurs, for it la 

 of little use raising fine hybrids It 

 their constitution is so poor that very 

 few amateurs can keep them alive 

 for more than two or three seasons. 

 Hence, in selecting the most vigorous 

 seedlings from the seed-pan, consid- 

 eration should always be given to the 

 parentage involved. In many in- 

 instances the (>ualities desired to be 

 perpetuated belong to a vigorous 

 parent, and in this case the cultiva- 

 tor acts wisely in selecting the strong- 

 est seedlings. — The Orchid M'orld.
