 caulinis inferioribus lineari-oblongis obtusis superioribus linearibus acuminatis sursum de- 

 crescentibus, spica oblonga pedunculata (a foliis remota) tetragona densa bracteata imbricata, 

 bracteis ternis duabus lateralibus subulatis tertia late ovata acuminata concava ciliata calycem 

 5-dentatum estriatum ! sequante, corolla? (parvue) tubo subrecto, limbo subaequaliter 5-lobo 

 lobis oblongis undulatis, capsulis inclusis. 



Hab. Canton; Mr. Millett. 



This agrees in many respects with B. cruciata, Ham. (Benth. Scroph. Ind. p. 11,) but it appears from Mr. 

 Bentham's specific character of the latter, to be quite distinct. The whole plant, as is usual in tiie genus, 

 becomes black by drying. 



SIPHONOSTEGIA. {Benth.)— Pbismatanthus. Hook, et Am. MS. 



Calyx tubulosus, subcoloratus, decemstriatus, versus faucem paullum angustatus; limbo 

 subaequaliter quinquepartito, laciniis oblongo-linearibus, duabus superioribus rectis, tribus 

 inferioribus deflexis. Corolla ringens, tubo angusto calycem sequante : labium superius 

 rectum, indivisum, concavum; inferius trilobum, subdeflexum. Stamina quatuor, didy- 

 nama, ascendentia, sub labio superiore posita. Antherae incumbentes, loculis discretis 

 parallelis basi acutis muticis. Stylus rectiusculus simplex. Stigma capitatum, subbilobuni. 

 M Capsula oblonga recta, valvulis integris." Benth. — Herba erecta, ramosa, cano-pubescens. 

 Folia subopposita, circumscriptione triangularia, basi in petiohim attenuata, 3-parlita, seg- 

 mentis lateralibus divaricatis, omnibus inciso-pinnatifidis. Rami Jlorigeri simplices. Folia 

 floralia minus dissecta quam caulina, inferiora alterna, superiora opposita. Flores axillares, 

 solitarii, breve pedicellati, bracteolis duabus sub calyce parvulis, linearibus. Calyx fere

Hab. Macao and the adjacent islands; Rev. G. H. Vachell, n. 184. 



This approaches very much in character to Bartsia, from which it is distinguished by the calyx, and to 

 Pedicularis, from which it is separated by the corolla and calyx. In habit it is not allied to any genus witii 

 which we are acquainted.
