leaves towards the extremity are 2^ in. in length, and 1 in. in breadth. The raceme, simply 

 spicated, rises in the dichotomy of the branches ; the peduncle is ^-f in^ long, very 

 closely marked by the cicatrices of the abortive flowers, seldom leaving more than 

 2 flowers at the apex, on slender pedicels 6-8 lines long ; the ovate sepals are 1 line long ; 

 the tube of the corolla is 5 lines long, narrowly cylindrical above, ventricose below the 

 middle; the segments are insequilateral and oblong, 3 lines long, 2 lines broad, of a 

 reddish colour, simply convoluted sinistrorsely in sBstivation. The stamens are seated in 

 the swollen part of the tube; the filaments arise out of 6 pilose lines, a little above 

 the base of the tube; the anthers* twice the length of the filaments, are 2.1obed 

 at their base, acuminated by a lanceolated membrane. No disk. Ovaries 2, pointed 

 oblong.

A species well distinguished from the former by its more slender branchlets, not 

 thickened at the nodes, by its smaller, more lanceolate, very membranaceous leaves, 

 almost sessile; branchlets striolated, dichotomous; leaves narrowly oblong, gradually 

 cuneate and insequilateral at the base, with a long narrow acute acumen, very slender 

 arcuately ascending nerves, very unequal at each node, 85-2^ in. long, 1-f in. broad, on 

 petioles scarcely more than \ line long, or sessile. The peduncle, as in the preceding, 

 is seated in the dichotomy, |— 1 in. long, densely crowded with cicatrices, rarely more 

 than 3- or 4-flowered at the summit, on pedicels 6-8 lines long ; sepals 1 line long ; tube 

 of corolla equally cylindrical, a little swollen above its base, very slender, 5 lines long, 

 segments unequally linear, 2 lines long, \ line broad, of a pale yellow or whitish colour, 

 convoluted sinistrorsely in aestivation ; stamens as in the preceding species, enclosed in 

 the swollen inferior portion of the tube ; no disk ; 2 conical oblong ovaries.

A species near P. diversifolia : branchlets very slender, with annular nodes 1-1^ in. 

 apart ; lower leaves in subinequal pairs, 3 and B^ in. long, 1-ly in. broad, on petioles 

 5-6 lines long ; the upper pairs of leaves half that size ; axillary panicles on slender 

 peduncles 9 lines long, bearing about 4 alternate flowers on pedicels 3 lines long ; sepals 

 1| line long j tube df corolla 6 lines long, segments 2^ lines long.
