Cathcartii and V. Sanderiana, and in habit neither resem- 

 bles either the original .! ths of Bluine (-1. moschi- 

 fera, Blume, Rumpli. iv. 55, t. 196 and 199 D. l!> nant) 

 Fh Reichb. f.) or P. Lowei, Lindl. (Tlenanthera L< 

 Reichb. f. Tab. : >745), which latter Reichenbach asso- 

 ciates with A. mo* . Bl., referring both to a section of 

 Renanthera. Upon the whole I should be disposed to 

 leave the Arachnanthes where Reichenbach has kept them, 

 under Renanthera,aiLd to bring V, ■ md Sanderiana 

 together under Emm ralda either as a section of Voa da or a 

 distinct genus. Reichenbach himself appears at one time 

 to have regarded P. Sanderiana as an Esmeralda, for he 

 cites Esmeralda 8anderiana, Reichb. f., under his descrip- 

 tion of it in Gard. Chron. N. S. xvii. -588, as a synonym. 



P. Sanderiana is a native of the Island of Mindanao, one 

 of the Philippines, whence it was imported by Mr. F. 

 Sander. I am indebted to W. C. Lee, Esq., of Downside, 

 Leatherhead, for the beautiful specimen lure figured, which 

 flowered in his famous collection in October last. The 

 species is a remarkably free flowerer; single plants are 

 described as producing five spikes at a time, and these 

 spikes as bearing forty-seven flowers and buds, thirty-four 

 being open simultaneously. — J. D. H.
