 Leaves 5'5 to 8"5 in. long, narrowly elliptic or sub- 

 obovate-elliptic, usually glabrous ; reticulations distinct, 

 especially below, as are the 5 or 6 pairs of main-nerves; 

 flowers pubernlous ; fruit obliquely elliptic ... 42. L. Maingayi. 



Leaves 3'5 to 6 in. long, oblong-elliptic or lanceolate, 

 everywhere glabrous ; reticulations and 7 to 10 pairs of 

 main-nerves faint; fruit depressed-trigonous or snb-

1. Lasunthus scabridus, King & Gamble, n. sp. Young branches 

 -about as thick as a goose-quill, glabrous, black when dry. Leaves coria- 

 ceous, oblong or oblong-elliptic, shortly acuminate, the base narrowed 

 and usually slightly unequal ; both surfaces pale-brown when dry, rugu- 

 losely reticulate, scaberulous from numerous short stiff hairs with large 

 bulbous bases, the midrib prominent and hirsute, the main-nerves and 

 veins depressed, under surface with non-bulbous hairs longer and softer 

 than those of the upper ; tbe midrib and 10 to 13 pairs of curved spread- 

 ing main-nerves hirsute like the midrib; length 4'5 to 8 in. ; breadth 

 1*35 to 2-35 in.; petiole '5 to '7 in.; hirsute; stipules broadly triangular- 

 acute or obtuse, thickly coriaceous, glabrous, "4 or "5 in. long, and near 

 ly as broad, persistent. Glomeruli somewhat shorter than the peti- 

 oles, sessile, dense, many-flowered, partly covered by the stipules when 

 young, bearing very numerous linear obtuse bracts, black, glabrous and 

 shining on their posterior surface, but on the edges and in part cover- 

 ed with coarse bristly hairs. Flowers few, sessile, much shorter than 

 and concealed amongst the bracts. Calyx narrowly campanulate with 

 a glabrous tube, and 5 lanceolate pubescent lobes. Fruit glabrous, ex- 

 cept the persistent calyx-lobes, about -2 in. long ; pyrenes 5, rugulose.

2. Lasianthus Griffithii, Wight in Calc. Journ. Nat. Hist. VT, 

 505. Young branches as thick as a swan's-quill, terete below but com- 

 pressed in the very young parts, sparsely and deciduously pubescent, 

 ultimately sub-glabrous, dark-colouied when dry. Leaves large, thickly
