Gabriel, Rio Negro (Spruce 2110). 

 A plant bearing mucli the appearance of Anacampta angulata, especially in its deeply 

 fossate petioles. The branches are trigonous, dilated at the axils, which are 2J-3^ in. 

 apart; the leaves are very oblong, subcuneate and insequilateral at their base, con- 

 stricted at the apex into a narrow acumen 1 in. in length ; they are chartaceous, bright 

 green above, sulcate at the 24 pairs of divergent immersed nerves, which terminate in 

 the reflected margins, paler and yellowish opake below, midrib and nerves prominent, 

 with transversely reticulated veins, 15 in. long, 3-3^ in. broad, on stout channelled 

 petioles 3 lines long, deeply fossate at the base and conjoined across the nodes by a 

 transverse ridge ; panicle lateral, fixed 4 lines above each node, on a peduncle barely 



1 in. long, bearing 8 or 10 flowers on branchlets 1-2 lines apart, each supporting 



2 flowers and 2 bracteoles at its apex, on pedicels 3 lines long ; calyx tubular at its base, 

 9 lines long, divided, above into 5 obtuse lobes 3 lines long, the tubular portion being 

 fleshy, and furnished inside with numerous lanceolate scales in several series; the tube 

 of the corolla in bud is as long as the calyx, the segments somewhat shorter, very gib- 

 bously ovate, sinistrorsely convolute in aestivation ; stamens and disk as in the generic 

 character. 



A drawing of this species, and the analysis of its flower, are shown in Plate VIII. b.

In Gruiana ad Acarouari (Sagot 394) : non vidi. 

 A species near the preceding. It is a tall shrub, with subscandent branchlets, very 

 compressed at the nodes; leaves ovate, sometimes acuminate, suddenly constricted at 

 the base upon the petiole, subchartaceous, patent, pale green on both sides, with about 

 12 pairs of divergent nerves, 6|-8 in. long, 3j-4^ in. broad, on thick, short, channelled 

 petioles 1^2 lines long, fossate at the base, their margins conjoined across the node by 

 a transverse ridge; panicle axillary or terminal, bearing several reddish-yeUow odo- 

 riferous flowers on a peduncle 9-12 lines long; calyx: 1^ lines long, tubular at its 

 base, and divided halfway down into 5 oblong obtuse lobes, bearing within, at the base, 

 several lanceolate scales ; tube of corolla cylindrical, slender, twice the length of the 

 calyx ; stamens inserted in the middle of the tube ; disk cylindrical, adnate, deeply pluri-
