 MTS., alt. 2000 ft., J. D. H. $ T. T. MARTABAN, Wallich. 



Branches robust. Leaves very variable, 6-7 by 2-2 in. in the oblanceolate forms, 

 8-10 by 4-6 in. in the broader forms, pale green or dark when dry, base acute or 

 rounded ; nerves strong, close-set, subhorizontal or ascending, not arched ; petiole 

 - in. ; stipule's f in., ovate, lax, entire or 2-3-clefb. Cymes 2-3 in. diam. ; peduncle 

 stout, 4 in. or less; branches whorled or opposite, together forming a flat-topped 

 corymb ; bracts an,d bracteoles minute, caducous ; flowers minute, subsessile. Calyx 

 hemispheric; limb truncate, obscurely toothed. Corolla-tube very short, throat 

 villous. Fruit ^ in. diam. ; pyrenes semi-circular in section, quite smooth. Seed 

 ventrally flat with a forked median groove. 



47. P. silhetensis, Hook. f. ; cymes and leaves beneath pubescent or 

 glabrate, leaves large stoutly petioled oblong or elliptic acuminate coriaceous, 

 nerves 15-20 pair strong, cymes terminal and axillary long-peduncled corymbi- 

 form ebracteolate, fruit large pedicelled ovoid globose or ellipsoid smooth. P.

UPPER ASSAM, Griffith; SILHBT, CACHAR, and the KHASIA MTS., ascending to 

 4000 ft., De Silva, &c. 



Branches very stout. Leaves 6-14 by 3-5 in., pale when dry, coriaceous ; nerves 

 strong, arched ; petiole ^-l^in. ; stipules 1 in., broadly ovate, often cleft. Cymes 

 .2-4 in. diam., pubescent or puberulous ; peduncle 3 in. and less, very stout ; branches 

 usually whorled, very stout, forming a corymb, spreading or deflexed in fruit ; bracts 

 and bracteoles minute, caducous; flowers small, pedicelled. Calyx obconic; limb 

 .almost truncate. Corolla-tube very short, throat with an exserted brush of erect hairs. 

 Fruit %- in., base rounded, smooth ; pyrenes semicircular in section, quite smooth. 

 Seed ventrally flat. My own Khasian specimens have large ovoid fruits with no 

 trace of a ventral groove in the seed and corymbiform cymes. Cachar ones from 

 Keenan have a more irregular cyme, with smaller broader fruits and a deep T-shaped 

 ventral groove, which, however, sometimes quite disappears. This species very closely 

 resembles P. fulva, differing in the ebracteolate flowers and in the fruit. 



48. P. montana, Blume Bijd. 960; glabrous, leaves on long slender 

 petioles elliptic oblong or lanceolate acuminate very membranous, nerves 8-10 

 pair distant slender, cymes terminal and axillary sessile or peduncled,.subcorym-

A small subherbaceous species ; branches slender, soft. Leaves 3-7 by 1-3 in., 

 usually pale green when dry ; nerves slender, arched ; petiole -1^ in. ; stipules \ in., 

 triangular, entire. Cymes usually peduncled with whorled branches 2-3 in. diam. ; 

 flowers dense or lax, pedicelled. Calyx-limb spreading, teeth triangular. Corolla- 

 tube long for the genus, -fc in., glabrous, throat with a brush of hairs. Fruit i- 

 in., pedicelled, red, rugose, ridged at the commissure. Seed thin, plano-convex, flat 

 ventrally, without a groove. Habit entirely of a Chasalia, but the corolla-tube is 

 very short and the seed not concave ventrally.
