1. Mussaenda MUTABiLrs, Hook. fil. Ic. Plant 1718. A climber, 15 to 

 40 feet long; young branches thinner than a goose-quill, terete, glabrous. 

 Leaves membranous, on rather long petioles, broadly elliptic to elliptic- 

 rotund from near the base ; apiculate or shortly triangular acuminate at 

 the apex, both surfaces glabrous ; maiu-nerves 7 to 9 pairs, curving 

 upwards, thin but prominent on the lower surface when dry ; the reticu- 

 lations open and transverse ; length 5 to 7 in. ; breadth 3 to 45 in. ; 

 petiole '75 to 1*25 in. Stipules forming an irregularly toothed pubescent 

 ring of teeth of an inch or less in depth. Cymes terminal, much shorter 

 than the leaves even in fruit, 2-branched, the stipules shorter than those 

 of the stem. Flowers 1*5 to 2 in. long, from 8 to 12 ; bracteoles few, 

 like the calyx-lobes but smaller. Calyx-lobes equal, lanceolate some- 

 times linear-lanceolate, acuminate, sparsely strigose externally, tomentose 

 within, less than half as long as the corolla-tube, deciduous in the fruit. 

 Corolla orange red, the limb about 2 in. across when fresh, the lobes 

 elliptic-oblong, acute, with short coarse hairs on both surfaces ; the tube 

 cylindric, '1 in. wide, very slightly expanded towards the apex, adpressed- 

 pilose externally, pubescent internally. Fruit cylindric sub-clavate, 

 glabrous, faintly ridged, the apex blunt, narrowed at the base to the 

 short pedicels; length *5 to *7 in.; diameter about *3 in. Mussaenda

2. Mussaenda Wrayi, King n. sp. A climber or occasionally a 

 spreading shrub ; young stems thinner than a goose-quill, covered like 

 the leaves inflorescence and flowers with stiff more or less rusty hairs. 

 Leaves membranous, elliptic or obovate-elliptic, much narrowed to the 

 base, the apex shortly acuminate ; main-nerves 9 to 14 pairs, curving 

 upwards, thin but prominent on the lower surface ; length *4 to *8 in. ; 

 breadth 1'75 to 4 in. ; petiole *35 to *75 in. ; stipules free, lanceolate- acu- 

 minate, about *25 in. long. Cymes solitary, terminal, condensed in flower, 

 spreading in fruit, shorter than the leaves, the bracts lanceolate. Calyx 

 densely pilose, infundibuliform, *5 to '7 in. long ; the mouth with 5 deep 

 lanceolate usually equal teeth, occasionally one of the teeth petaloid,
