A trio of very distinct but extremely useful small-flowered 
Bpecies are 0. cucullatum, 0. ornithorhynchum, and 0. cheirc- 
phorum. Of these much the largest flowers are borne by the first- 
named, the sepals and petals being purplish, the lip rosy purple 
with deeper spots, some recent varieties being considerably richer 
in colour and with larger flowers than the older forms, while one 
has a distinct yellowish tinge. O. ornithorhynchum has very 
small fragrant rose or purplish flowers, but they are borne in such 
dense panicles that they amply compensate for this defect. A 
white-flownred variety is also in cultivation, and forms a beautiful 
companion for the ordinary type. O. cheirophorum is very 
similar to the last named in the size and form of the flowers and 
in the form of the panicle, but the colour is clear yellow, and 
therefore quite distinct from the preceding. It is, however, not 
so well known as those, and is well worth more attention, as the 
flowers are very fragrant and bright in colour. It is a native of 
New Grenada, where it was found by Warscc-wicz at an elevation 
of 8000 feet on the volcano of Cbiriqui, where it was “ flowering 
a warm house. The lip constitutes the great attraction of the 
flower, that being of great size, frequently inches in diameter, 
rich yellow in hue, and slightly lobed at the upper part. The 
flowers are borne in large-branched spikes or panicles, and a plant 
in good condition is one of the most striking Orchids during 
winter. It is a variety of 0. varicosum, but much superior to the 
ordinary type, and was introduced from Brazil about twelve years 
ago. Two other somewhat similar yellow-flowered Orchids are 
0. ampliatum majus and 0. bifolium majus, but these bloom in 
spring and early summer. Very handsome specimens of the 
former are occasionally seen at exhibitions, one of the finest being 
that shown by Mr. Childs of Gai brand Hall Gardens, Ewell.

or thinning the flower truss. I differ slightly from him in their 
management, as I transfer them from thumb pots into large GO’s, and 
winter them in them, and when they are started and the truss is 
formed I place them into 48’s, and when the truss is sufficiently 
expanded thin it to at least two-thirds. —J. Smith.

0. Rogersi. —This deserves a place amongst the be-t of the 
whole genus, and it is now a great favourite with all Orchid- 
growers, as it is very showy and very free when grown in pots in
