There is only one species described down here, the anther has this peculiar 

 shape (G. pandiiratum Ridl.), but in K. cochinchinensis Gagn. 1908, 64, 

 tab 3, 21-29, which evidently belongs to Gastrochilns, the anther is almost 

 identical, but here the labelluni is obcuneate not saccate, like that of G. 

 anomaliim K. Sch , and the inflorescence not dense. Probably here belongs 

 also G. vittatum (N. E. Brown) Val. of which 1 could not examine a flower. 



2b. Anthercells parallel, oblong, adnate to the sides of a fleshy hip- 

 pocrepiform, more or less prolongate connective, opening by terminal pores. 



Here belong G. Ciirtisii, Baker, G. grandifolium Val., Cyovanum K. Sch., 

 G. Lörzingii Val., G. apiciilatum Val., and probably G. hirtum, Ridley, 

 G. bractescens Ridley and G. striatum Val. Though the structure of the anther is 

 rather different in these two groups, still G.y'öyfl/zum with terminal pores and 

 G. panduratum with iongitudical splits are very nearly related and form 

 together a natural group, in which the connective is projecting. To this 

 combined group belong several species described by Ridley. It is distinguished 

 from Eugastrochiliis principally by the presence of the crest of the anther 

 while the way of dehiscence of the cells is unknown in most species. 



I propose to call this group: Paragastrochilus. 



If the structure of the inflorescence is compared in the diverse species 

 examined, two rather different types must be distinguished. 



The first one is found in the first type of the genus and excellently 

 described by Wallich. 



It is a "terminal spike", sessile (on the top of the leafstem) oblong, 

 attenuate, acute, the base hidden in the upper sheaths, bearing flowers 

 at the face side only, at the backside plane and imbricate by the erect, 

 alternate, appressed, subdistant, one inch long, green, lanceolate bracts. 

 Rachis thick fleshy, rather plane, in the middle of the backside denudate." 

 (Wallich 1. c.) 



This definition accords exactly with the inflorescence of G. /7ancf«ra/«m 

 There too the rachis is thick, fleshy, rather plane and denudate at the 

 backside, but while this is elongate (125 mm. long) in G. pulcherrimiim, 

 the rachis is about 25 mm long here. Moreover the spike is long peduncled 

 (see RoscoE 1828 tab. 26), the peduncle is nude and consists of two inter- 

 nodes, the lower short, the uppermost rather long but varying according 

 to the age of the bulb, it can reach 120 mm. The whole peduncle 

 with the base of the inflorescence is enclosed by the imbricating very 

 long sheaths of the 3 to 5 radical leaves and outside of these by 

 several large scales or bladeless sheaths diminishing in size to the exterior. 

 They are often brownish-red-coloured. Near the top of the peduncle is 

 inserted the last normal leaf, and alternating and imbricating with it the 

 outermost green bract of the inflorescence which sometimes has a small 

 blade. Between these two sheaths the inflorescence is enclosed. This con-
