THE ORCHID WORLD. 



Importation of Orchids to America. 

 — The Horticultural Board, Washington, has 

 ruled that Orchids are included in the 

 definition of nursery stock, and cannot, there- 

 fore, be imported without a certificate of 

 freedom from disease. The importation of 

 plants by post has been prohibited by the 

 United States Government.

Orchids at Hounslow. — Miltonia 

 spectabilis grows exceedingly well with me. 

 It gets plenty of light, moisture, and air ; m 

 fact, Cattleya requirements suit it. Each 

 bulb makes two breaks every year. With 

 reference to growing too many kinds of 

 plants in the one house. I have about 

 400, including Odontoglossums, Laslias, 

 Cattleyas and their hybrids, Cypripediums, 

 cool and warm, Dendrobiums, Cymbidiums, 

 Phalaenopses, Calanthes and Vandas, and 

 every one is doing well. It seems to be 

 entirely a question of finding suitable 

 positions for the plants. Odontoglossum 

 crispum I do not put myself out to cultivate, 

 but notwithstanding the fact that a warm 

 sunny day will run the house temperature up 

 to 95 degrees, they thrive, making good 

 bulbs, stiff leaves, and plenty of bloom. The 

 house is frequently without any attention 

 during the greater part of the day, and I often 

 think that the dry atmosphere, comparatively, 

 is more natural. — Henry R. Stcrrcti, " Elgin"

THE MAKING OF A CRISPUM. 



I have written and said at various times 

 a great deal hereon, but I think I have not 

 previously written upon the form known as 

 crispum roseum. For a long time past the 

 rose colour was somewhat more unexplainable 

 than the blotching, but I had no doubt that 

 it was also the ultimate result of hybnclity. 



I have now in bloom a seedling raised upon 

 a fine round white form crossed by crispum 

 Crawshayanum (which is a heavily blotched 

 open form ; its blotches cover two-thirds of 

 its area). Neither of the parents have any 

 rose in the ground of the petals, but this 



[November, 1913. 



seedling is distinctly rose shaded all through 

 the area where are the big blotches of the 

 pollen parent, and on the backs of the petals 

 is tracery in the veins of the form of the 

 blotch. 



The sepals have a small " Bonnyanum " 

 spot with a good deal of rose on the backs. 

 The lip is white like those of both parents, 

 but has the usual blotch. In form it is fine 

 and oblong, whereas that of the pollen parent 

 is very long and spear shaped. The column 

 head and wings are very deep burnt sienna- 

 crimson. 



There seems no doubt that the rose in a 

 crispum is the result of the degradation of 

 the blotches, but how the deep brown of 

 luteopurpureum and Lindleyanum became 

 rosed is matter for further investigation. 

 Sunlight appears to do it, but the chemist 

 can help us hereon.

ODONTOGLOSSUM WILSONIl. 



crispum Harrj-anum crispain triumphans 



I I I I 



I - I 



crispo-Harryanum harvengtense 



Wilsonii. 



A plant bearing this name and parentage 

 was raised at Walton Grange and shown at 

 the Manchester Orchid Society, January 19th, 

 191 1. I have lately bloomed one of the same 

 parentage, and a more remarkable case of a 

 hybrid being " half and half " of each parent 

 I have rarely seen. 



The sepals and petals are those of 

 harvengtense, deep yellow, blotched, as usual, 

 with dark brown, the only deviation being 

 some purplish-brown shading at the bases of 

 the petals. The lip is that of crispo-Harry- 

 anum, but more pointed, light cream-yellow, 

 spotted at the sides, having a small purplish- 

 brown blotch in the centre. The crest 

 and channel are those of harvengtense, 

 slightly modified, the column almost that of 

 Harryanum.
