This species has the habit and general form of the flowers of Bendrohium foliosum, 

 Brongn. Voy. Coq., Bot. 203, t. 43 (Pseuderia fol'wsa, Schlechter), of which I have seen 

 no type, but it diff"ers in the papillose lip and in the shape of the anther, which is figured 

 and described as acuminate. The anther iu this species is small, and laterally flattened 

 with a narrow rounded crest running down the back, the anther-cells are erect, elliptic, 

 parallel, and contain two pairs of closely appressed narrow elliptic pollinia. 



The plant referred by me to Eria foUosa in Forbes's collection from Sogere in New 



Guinea, in Journ. Bot. xxiv. (1886) p. 326, is neither this plant nor the Fendrohimn 



Joliosum of Brongniart. The column and anther resemble those of D. nigricans, but 



the lip is obovate with a very blunt papillose point, while the pedicels are much 



shorter, the flowers smaller, and the leaves broader. 



Bendrobitmi spinescens, Lindl. in Journ. Linn. Soc. iii. (1859) p. 14, which is given by 

 Kriinzlin as a synonym of D. foliosum, Brongn., is based on an extremely rough sketch 

 by Eeinwardt without details. Lindley saw no specimen of it, and the locality is 

 doubtful. It differs entirely from the figure of F. foliosum, Brongn., in the flowers 

 being apjiarently sessile, instead of long-pedicellate, and very much larger, with patent 

 oblong obtuse petals and sepals. The foliage and the form of the raceme resemble those 

 of F. foliosum. I do not think it is possible now to guess what plant Reinwardt 

 intended to figure, but it could not have been F. foliosum. 



Kriinzlin, in 'Pflanzenreich,' iv. 50, ii. B, 21, classes F. foliosum, Brongn., and F. simile, 

 Schlechter, in the section Eugrastidimn of Fendrobium, from which he excludes all of 

 Blume's species of Grastidium except G. rugosum. But Grastidium, if confined to tlie 

 typical species and its allies, is to me a sufiiciently distinct section, which I retain. It is 

 characterised by its leafy stem with a short two-flowered raceme protruding through 

 the leaf-sheath, and subtended by two pairs of bracts, one usually short and semi- 

 orbicular, the other longer. Schlechter has made the genus Pseuderia for D. foliosum.
