arms of column obliquely truncate or 2-lobed. Capsule J in. long, turgidly ellip- 

 soid. — Lindley in describing the Chinese plant assumed it to be the Sendrobium 

 biforiBOT of "Wall. Cat. 2002, which consists of two very distinct Penang plants, a 

 Dendrobium (D. bifarium, Lindl., see v. V. p. 732) and an Appendicula in fruit only, 

 very like indeed the Chinese plant, but differing in the numerous lateral racemes. 

 Specimens from Perak in flower exactly accord in foliage with Wallich's Penang in 

 having many racemes, but differ in having a more 3-lobed lip, a broader margin to 

 the base of the lip, and a 2-lobed callus. Assuming that the Perak and Wallich's 

 Penang plant are the same, they may be either a different species from bifaria, or a 

 variety. For the present it is safer to assume the latter and to call it : — 



Vak. ? Wallichiana ; racemes numerous lateral, lip with a broad rounded base 

 surrounding the caloeolar membrane, callus of disk 2-lobed in front. Dendrobium 

 bifarium, Lindl. in Wall. Cat. 2002, in part. — Penang, Wallioh. Perak, 

 Scortecyiini.
