178 CXLVIII. ORCHIDE^:. (J. D. Hooker.) [Supplement, $c. 



18/2. COLLABIITM:. 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. EEIA, insert 



19/1. CLADERIA. Terrestrial, subscandent. Leaves plicate. Inflorescence ter- 

 minal. Lip sessile at the base of the long sigmoid column. Pollinia 2 ? 



21. PACHTSTOMA, add to description. Flowers small ; and insert after it 



21/1. IPSEA. 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. ETJLOPHIA. See remarks under Subtribes EULOPHIE.E, at p. 177 of this 

 volume. The character of "petals like the dorsal sepal," is subject to many 

 exceptions. 



41. CYPEROECHIS, though removed in " Gen. Plant. " from proximity to Cym- 

 lidium, should stand next to it. The two genera are hardly separable. After it 

 insert 



41/1. CREMASTEA. Sepals and petals and lip very narrow and conniving in a 

 tube. Leaf solitary on a tuberous rhizome. Scape leafless, sheathed ; flowers race- 

 mose, secund. 



Subtribe 3. CYRTOPODIE-E and 48; Plocofflottis. For remarks on these see 

 Subtribe Eulophiea, at p. 177 of this volume. 



Subtribe 4. SARCANTHE.E. The classification of the genera of this subtribe 

 presents great difficulties. In so far as the Indian genera are concerned I have not 

 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. 



49. LTJISIA. The Crislaria 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 Vanda. The lip of one species of Sect. Cristaria 

 is spurred or saccate as in Vanda, of another it is flat as in Luisia, without spur or 

 sac. 



50. COTTONIA. Replace the character by, Sepals and narrower petals spreading. 

 Lip sessile, not jointed at the base of the column, flat. Stipes of pollinia long, 

 narrow. Raceme very long-peduncled, and follow it with 



50/1. DIPLOPBOEA. Sepals and broader petals spreading. Lip with the sides 

 adnate to the sides of the column, cyrnbiform, with a compressed bicaudate tip. 

 Stipes of pollinia short, narrow. Raceme very shortly peduncled. 



P. 672. 53. PHALJENOPSIS. Add to character of .lip, disk with a forked callus 

 or plate, and 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. 



55. RHYNCHOSTYLIS is placed by Bentham in a division of Sarcanthea with a 

 foot to the column and a mentum, but appears to me to have these characters very 

 obscurely if at all. The lip and spur are exactly those of Saccolabium. 



56. SAECHOCHILTJS 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. BRIDES. 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 Vandce, and those of Section II. ** 

 resemble Saccolabia. The stipes of the pollinia is sometimes short and broad, 



60. VANDA. See above under 58 ^Brides, and 49 Luisia for remarks. The Sect. 

 Anota (V. densiflora) has so short a foot to the column that it might well be placed 

 in Saccolabium. The stipes of the pollinia varies greatly in length and breadth,
