178 certen, ORCHIDE®. (J.D. Hooker)  [Swpplement, $c. 
18/2. COLLABIUM. Scape tall, raceme long. Lip jointed on to the trumpet- 
shaped foot of the column. Pollinia 2, 2-cleft, united by a viscus. (See Vol. v. 
p. 784.) 
After 19. ERIA, insert— 
19/1. CLApERIA. Terrestrial, subscandent. Leaves plicate. Inflorescence ter- 
minal. Lip sessile at the base of the long sigmoid column. Pollinia 2? 
21. Pacnysroma, add to description. Flowers small; and insert after it— 
21/1. IPs. Scape leafless. Flowers large. Sepals spreading. Column elongate, 
foot 0. Pseudobulb 1-2-leaved. 
28. For JOSEPHA read JOSEPHIA. 
29. GLOMERA. Cancel this genus. (See Vol. v. p. 823.) . 
P. 671. EULOPHIA. See remarks under Subtribes EULOPHIEA, at p.177 of this 
volume. The character of ‘petals like the dorsal sepal,? is subject to many 
exceptions. 
41. Cyprrorcuis, though removed in “Gen. Plant.” from proximity to Cym- 
bidium, should stand next toit. The two genera are hardly separable. After it 
insert— 
41/1. CREMAsTRA. Sepals and petals and lip very narrow and conniving in 4 
tube. Leaf solitary on a tuberous rhizome. Scape leafless, sheathed ; flowers rac 
mose, secund. 
Subtribe 3. CyrropoprEm and 48. Plocoglottis. For remarks on these st 
Subtribe Eulophiec, at p. 177 of this volume. 
Subtribe 4, SAncANTHEX, The classification of the genera of this subtribe 
presents great difficulties. In so far as the Indian genera are concerned I have noi 
been able to improve upon Bentham's arrangement ; though I find numerous excep- 
tions to the characters given under the three subdivisions marked by stars. i 
49. LvisrA. The Cristaria section of Vanda unites that genus with this, 
The incurved sepals and petals of Sect. Cristaria are those of Luisia, but the foliage 
and habit are those of most Vande. The lip of one species of Sect. Cristata 
is spurred or saccate as in Vanda, of another it is flat as in Luisia, without spur 0T 
sac. 
50. CorroNIA. Replace the character by,—Sepals and narrower petals spreading. 
Lip sessile, not jointed at the base of the column, flat. Stipes of pollinia Jong: 
narrow, Raceme very long-peduncled, —and follow it with— 
50/1. Diptoprora. Sepals and broader petals spreading. Lip with the sides 
adnate to the sides of the column, cymbiform, with a compressed bicaudate tip. 
Stipes of pollinia short, narrow. Raceme very shortly peduncled, 
P. 672. 53. PHaLzNorsis. Add to character of lip, disk with a forked callus 
or plate, aud after foot short, add—or long or 0. 
54. Doritis. In this genus the foot of the column forms a conical mentum 
with the lateral sepals. 
95. RHYNCHOSTYLIS is placed by Bentham in a division of Sarcanthec with & 
foot to the column and a mentum, but appears to me to have these characters ver 
obscurely if at all. The lip and spur are exactly those of Saccolabium. 
56. SARCHOCHILUS is inconstant as regards the presence or absence of a foot to the 
column, and in having a mentum or spur or neither. It is a truly polymorphous 
genus, incapable of precise definition. 
58. ÆRIDES. I do not find the lip to be truly articulate with the foot of the 
column as described in “ Gen. Plant.” The species of the first section with terete 
leaves closely approach the terete leaved Vanda, and those of Section l4 
resemble Saccolabia. ‘The stipes of the pollinia is sometimes short and broad. 
60. Vanna. See above under 58 ZErides, and 49 Luisia for remarks. The Set 
Anota (V. densiflora) has so short a foot to the column that it might well be pla 
in Saccolabium., The stipes of the pollinia varies greatly in lejjgth and breadth.
