me to be more nearly related to Cyrtopodiea? than to Cymbidiea?, 

 to which, in some respects, it might be transferred. 



Cyrtopodium, Br., now consists of about twenty species, dispersed 

 over tropical America, Africa, and Asia. It was originally 

 founded on the C. Andersonii, Br., which, with a few closely allied 

 American species, has the raceme branched and the lateral sepals 

 only very shortly aduate to the basal projection of the column, 

 and was extended to embrace several Old- World species with simple 

 racemes and the lateral sepals adnate to the end of the basal 

 projection. Lindley afterwards proposed separating the latter 

 generically, under the name of Cyrtopera. But the geographical 

 distinction can no longer be maintained, for the American C. 

 Woodfordi has the chai^acters of Cyrtopera. Moreover, the Asiatic 

 C.flava, Lindl., and the Mascarene C. plantaginea, Liudl., have 

 the lateral sepals almost free from the basal projection, as in the 

 typical Cyrtopodium, whilst the raceme is simple, as in Cyrtopera. 

 The whole, therefore, are now reunited into one fairly natural 

 genus under the original name. C.foliosa, Liudl., however, from 

 South Africa, is not a congener, but appears to be a EulopJtia, 

 near E. cochhata, Lindl. 



Govenia, Lindl., including Eucnemis, Lindl., consists of about 

 ten American species, exceptional in the sub tribe by the inflo- 

 rescence terminating leafy stems. Pteroglossaspis, Beichb. f., a 

 single Abyssinian species, is the only exclusively Old-World genus 

 of the subtribe with fleshy pseudobulbs. 



Zygopetalum is an American genus of about forty species. I 

 cannot concur with Blume in uniting it with Eulophia, but I 

 woidd add to it several small genera proposed by Lindley or 

 Beichenbach, most of which have, indeed, been already joiued 

 with it by Beichenbach. Amongst these I would recognize the 

 following six as sections: — 1. Zygopetalum proper; 2. Zygo~ 

 sepalam, Beichb. f. ; 3. Huntleya, Batem., including GaJeottia, 

 A. Bich. ; 4. Bollea, Beichb. f. ; 5. War&zeiviczella, Beichb. f., 

 including Pescatorea, Beichb. f. ; and 0. Promencea, Lindl., ex- 

 cluding the racemose species and including Kefersteinia, Beichb. 

 f., and Chaabardia, Beichb. f. 



Grobya, Lindl., two Brazilian species, calls for no comment. 

 Cheiradenia, Lindl., one Guiana species, is not sufficiently known 

 to be certain of its affinities, and our specimens do not afford 

 materials for a proper examination. 



Aganisia, Lindl. (Koellensteinia, Beichb. f.), has about six
