A species with much the habit of P. heteropJiylla. It is a shrub 5-6 feet high, much 

 branched, its branches paUidly fuscous, slender, terete, compressed at the nodes, divari- 

 cately dichotomous ; leaves heterophyllous, spreading, the larger one elliptic, acute, and 

 almost obsoletely petiolated at the base, 5§ in. long, 2^ in. broad, the opposite one ovate 

 or roundish, sessile and subcordate at the base, 2^ in. long, 1| in. broad, glabrous, con- 

 col orous ; peduncle very slender, erect in the dichotomy of the branchlets, 1-1^ in. long, 

 bearing near its apex 4 approximated flowers, on pedicels 3 lines long, the lower ones 

 caducous; sepals lanceolate, 1 line long; tube of corolla very slender, 7 lines long, 

 slightly swoUen near the base, subpUose within, segments 3 lines long, 1 line broad ; 

 stamens inserted near the base of the tube, anthers slender, sagittate, subcoherent ; 

 ovaries 2, slightly tuberculated ; no apparent disk ; follicles 2, divaricated, one often 

 abortive, obovate, or obtusely elliptic, subcompressed, verrucously muricated, orange- 

 coloured. If in. long, IJ in. broad.

A species often confounded with the foUowing. Its branchlets are slender at the ex- 

 tremity, dichotomous, terete, and slightly 4-angular, swoUen at the axils ; lower down, 

 where the leaves have faUen off, they are marked by annular ridges at the nodes. The 

 opposite leaves are unequal in size at each axil, are thinly chartaceous, oval, obtuse, 

 or shortly acute at the base and subinsequilateral, suddenly attenuated at the summit 

 into a sublanceolate acumen; they have about 10 pairs of patently divaricated slender 

 nerves; at each node they are respectively 4|-3 in. long, 21-1^ in. broad, on channeUed 

 petioles 2-3 lines long, their margins conjoined across the node by an elevated ridge ; the
