PLATE 117.-—Bulbophyllum hirtum, Lindl. A plant; of natural size. Fig. 1 the petals, 2 flower,

7. Cirrhopetalum, Lindl. 
Epiphytal; usually with a creeping rhizome, but sometimes coespitose ; pseudo-bulbs 
l-rarely-2 leaved. eaves usually solitary from each pseudo-bulb, coriaceous and per- 
sistent; rarely in pairs, membranous and deciduous. Scape rising from the base of a 
pseudo-bulb. Flowers usually in whorled umbels, sometimes capitate, rarely racemose, 
cften dorsally compressed. Dorsal sepa! concave, short, rarely half as long as the lateral 
pair, and usually much shorter; lateral sepals usually much elongate and acuminate, 
‘oblique, often cohering by their inner edges, the bases adnate to the sides of the 
column or of its foot, Petals shorter than the dorsal sepal. Lip small, tumid, usually 
entire, always shorter than the dorsal sepal, jointed to the end of the foot of the 
column and more or less mobile. Column short ; its apex with two (rarely four) tooth- 
like appendages; the foot more or less produced. Anther bilocular ; pollinia 4, cohering 
in а single mass and sometimes attached by their lower ends to а mass of viscid 
tissue; the inner two usually small and lamelliform. 
A genus of about forty species, chiefly Indo-Malayan; very closely allied to Bulbophyllum, and not 
separated from that genus by any really good character, but artificially distinguished by the shortness 
of the dorsal and the great length of the lateral sepals, and by the flowers being usually in whorled 
umbels, rarely in racemes or heads. 
Pollinia without any viscus, 
* Lateral sepals cohering to their apices, or almost to their apices, to form 
a flattened blade. 
Leaves in pairs from coespitose pseudo-bulbs, caducous; flowers in 
drooping racemes. 
Dorsal sepal more than half as long as the lateral pair . 1. C. viridiflorum.

Scape not much longer than the pseudo-bulb . . 5. О. brevipes. 
The blade formed by the lateral sepals broader at the apex

Scape much longer than the pido alle, TR than or 
nearly as long as the leaf. 
Dorsal sepal and petals not ciliate; the petals awned 
` at the apex and with erose margins; the apex of 
the lip emarginate .
