1. HiPPOCEATEA FERRUGINEA, King n. sp. A climber ; young shoots 

 slender, glabrous, the older cinereous. Leaves coriaceous, elliptic-oblong, 

 sub-acute or shortly cuspidate, entire, the base rounded or sub-cuneate ; 

 both surfaces glabrous, shining, the reticulations rather distinct; main 

 nerves about 5 pairs, curved, ascending ; length 3"25 to 5"5 in., breadth 

 2 to 2*5 in., petiole '3 to '4 in. Panicles axillary, nearly as long as 

 the leaves, with large divaricating ferrugineous-pubescent pyramidal 

 branches. Flowers '2 in. long, on pedicels rather shorter than them- 

 selves. Sepals 5, rotund, concave, densely rusty-tomentose outside, 

 glabrous inside. Petals 5, several times longer than the sepals, oblong- 

 obovate, with long slender claws, conduplicate, rusty-tomentose outside, 

 glabrous inside, falcately curved so that the tips connive. Disc large, 

 its lower edge thickened and wavy. Stamens 3, the filaments flattened, 

 broad, reflexed ; the anther's sub-globular, 1-celled, with transverse
