edge, the said intramarginal nerve connected by many cross-nerves with 

 the hardened marginal nerve; reticulations netted ; petiole -15 to -25 in. 

 long, flattened. Umbels racemose, about 8- to 10-flowered, on a short 

 tubercular rachis at the end of a thickened pink peduncle reaching 1 in. 

 in length ; pedicels slender, 1 to 1-5 in. long, puberulous ; buds -25 in. 

 long, 5-angled, the incurved valvate corolla-lobes forming a central con- 

 cavity; flowers "white" (Maingay), nearly black when dry. Calyx 

 puberulous, pale pink ; tube very short ; lobes ovate-oblong, obtuse, 

 •05 in. long ; scales minute. Corolla -6 in. broad when open, glabrous 

 without, sparingly pilose within ; lobes obcordate, apiculate, inflexed 

 (when dry). Corona of 5 processes ; the lower and large lobes suberect, 

 laterally compressed, bladder-like (the interior of the cavity delicately 

 hairy), ovate, slightly apiculate ; the upper short, flattened, slightly 

 recurved, appressed to and covering the anther. Staminal- column 

 attached to the base of the corolla-tube ; anthers short, much inflexed 

 so as to lie nearly horizontal ; cells parallel above, divergent and empty 

 below ; appendages scarious, acute ; pollen-masses oblong-falcate, 

 pellucid on the outer margin, nearly horizontal, attached by thickened 

 caudicles to the rather large elongate pollen-carriers which are obtuse 

 above and 2-winged below. Style-ajMX 5-angled, flattened, with a short 

 central umbo having 5 divergent rays to the angles. Fruit not known.

7. HoYA coRONARiA, Blume Bijd. 1063 (1825), and Eumph. IV. 31, 

 t. 182, fig. 2 and t. 184 (fruit). A stout twining shrub, the upper 

 branches giving out roots on to the bark of trees and probably therefore 

 more or less epiphytic ; branches thick, velvety pubescent, the innova- 

 tions especially so. Leaves thickly coriaceous ; elliptic elliptic-ovate 

 or ovate-oblong, shortly acuminate at apex, rounded at base ; upper 

 surface when dry shining, wrinkled, puberulous especially on the mid- 

 rib ; lower surface pale brown, velvety-pubescent ; margins strongly 

 recurved ; 3 to 4 in. long, 1 to 2 in. broad ; midrib stout, impressed 

 above, raised beneath ; main nerves very obscure, about 5 to 7 pairs, 

 nearly horizontal ; reticulations not visible; petiole thick, velvety, -25. 

 to "75 in. long. Umbels racemose, rather few-flowered, on thick rachises 

 with large rounded tubercles '5 to 1*5 in. long, at the ends of thick 

 lateral velvety peduncles -5 to -75 in. long ; pedicels velvety, curved, 

 thick, -5 to 1 in. long ; buds depressed at top, the lobes decurved in a 

 hook ; flowers large, fleshy, about 1-5 in. in diam,, greenish-white 

 changing to ivory-white, then apparently to pink which darkens and 

 becomes speckled with purple (Ridley) ; the corona white. Calyx thick, 

 velvety without; lobes orbicular, -15 to -25 in. long; scales subulate. 

 Corolla very thick, glabrous within, villous without ; lobes triangular-
