348 MR. HENRY RIDLEY ON ORCHIDEZ AND 
has an evident affinity with Thrizspermum, but has the short 
stem of a Sarcochilus, an entire lip, and apparently no foot to 
the column, to which the sides of the lip are adnate. I believe 
that in reality the column has a foot, but it is adnate to the 
sides of the lip, and, excepting by the arrangements of the 
nerves, is indistinguishable from it. Perhaps it would be best 
to leave it as a distinct genus, as Sir Joseph Hooker appears 
inclined to do. 
Fornicaria has a thickened terete rhachis with persistent 
quaquaversal ovate acute bracts. The lip is saccate, with a 
small epichil (usually), and the side lobes are often rolled up 
so as to give the lip a trumpet shape. 
The oldest name for any species of this genus is Blume’s 
Dendrocolla, which, however, included Thriaspermum as well. 
Reichenbach’s Grosourdya, Bot. Zeit., xxii. (1864) p. 297, was 
made to include several of this section, but the type of the 
genus, (7. elegans, seems to bea very different plant. Thwaites’s 
Cylindrochilus, Enum. Pl. Zeyl., p. 307, belongs to the same 
genus, but it will cause less change to adopt Blume’s old name. 
In these genera the rhachis of the inflorescence grows very 
slowly, the flowers opening at considerable intervals of time, so 
that as much as a week may elapse between the opening of two 
consecutive flowers, and the whole inflorescence may take 
months to develop all its flowers. The blossoms are very 
fugacious, so that it is impossible for one to be fertilized by 
another on the same raceme. 
Sarcochilus I would propose to retain for the section Tubera, 
Blume, and of the ‘Genera Plantarum’ for the most part, to 
include all the species with a long foot to the column, a porrect 
spur, with a small, often fleshy, epichil. 
AscocuiLus I would propose as the name for a small genus in 
which the column has a very long foot, on the end of which is borne 
the lip, far from the body of the column. The spur is pendulous, 
rather long, with large lateral lobes, and a well-developed, 
sometimes bilobed epichil. 
In these two genera the inflorescence usually, at least, 
develops rapidly, so that several flowers may be open at once, 
and frequently all are open on the same day. 
Stereochilus, Lind]l., Micropera, Lindl. (Camarotis, Lindl.), 
Chiloschista, Lind]., seem to me distinct. They do not occur in 
our region as far as is at present known.
