1. IxoRA Brunonis, Wall. Cat. 6136. A shrub ; young branches 

 tbicker than a crow-quill, covered with short cinereous -brown tomentum. 

 Leaves thinly membranous, sessile, oblanceolate, sometimes sub-pan duri- 

 form, shortly caudate-acuminate, tapering much to the rounded or 

 minutely cordate base ; upper surface with the interspaces shining and 

 glabrous, the depressed midrib and 10 to 12 pairs of rather faint curved 

 ascending main-nerves minutely tomentose ; lower surface with minute 

 spreading pubescence especially on the prominent midrib, main-nerves 

 and reticulations, length 5 to 10 in. ; breadth 1*5 to 2*25 in.; stipules 

 with broad ovate bases with stout midribs, and long thin linear apical 

 tails, length (including the tails) '5 in. Cymes about 1*5 in. long, 

 12- to 20-flowered, on short tomentose peduncles, 4 to 6 collected in 

 corymbs on the apices of the branches, their bracteoles filiform and 

 hairy. Flowers sessile ; calyx '15 to '2 in. long, narrowly campanulate, 

 the 4 teeth narrowly lanceolate, acuminate, as long as the tube. Corolla 

 1 to 1*5 in. long, externally with long cinereous spreading deciduous 

 hairs, ultimately nearly glabrous ; the tube very narrowly cylindric, 

 glabrous and ridged inside, the throat hairy : limb '5 in. across, its 

 lobes 4, oblonge-elliptic, acute, spreading or reflexed, quite glabrous on 

 the upper surface, sparsely hairy on the lower. Anthers elongate, nar- 

 row, acuminate, deflexed, longer than their filaments. Stigma slender,
