petiole J-À in. Peduncles j-i in.; pedicels 1-1} in. Sepals shorter than the 
corolla-tube. Corolla 2 in. diam., white. Coronal-processes (mutilated) as long as the 
corolla-tube, apparently ovate, with the inner angle shortly spurred.—The only

Icones is a copy of Roxburgh's drawing, which represents a much larger leaved plant 
than the specimen.

crassifolia, Jacg. Eclog. t. 2; Traill. in Trans. Hort. Soc. vii. 22; from India; with 
leaves described as excessively thick, obsoletely spotted, petals truncate or obtuse, i$ 
unknown. Wight (Contrib. 38) refers it to the Chinese H. carnosa, Br., which name 
it would supersede. 
H. Fintaysonu, Wight Contrib. 38; Wall. Cat. 8166; Dene l.c.; stem stout, 
leaves 5-7 by 2 in. ovate-lanceolate obtusely acuminate densely thick penni-nerved, 
nerves prominent on both surfaces arched, intramarginal very distinct, petiole short 
stout.—Singapore, Wallich; Siam,? Herb. Finlayson. 
H. GYMNANTHERA, Wight. Contrib. 37; Wallich’s sheet of this consists of a leafless 
twig of a Hoya with buds, and a good specimen of Parsonsia spiralis. 
H. nicoparica, Br. in Wight Contrib. 36 (note under H. pendula, W. & A.); Dene. 
l. c.—Nothing is known of this. 
H. orrosrra, Don Gard. Dict. iv. 128 (Sperlingia opposita, Vahl; Wight Contrib. 
67), is H. Rumphii, Blume, a Moluccan plant. 
H. WarLicHIANA, Dene. l.c. 635; said to be mixed with Wallich's n. 8165 (H. 
latifolia), appears from Decaisne's description to be H. coronaria, Bl.

Naturhist. Selsk. Kiobenh. vi. 113), said to be a native of India, is unknown to me. 
. H.sr.? Amongst the drawings in Herb. Kew is one of a Hoya from Penang, 
with ovate-lanceolate acuminate 3-ple nerved leaves 6 in. long suffused with purple, 
red and white flowers } in. diam. having long flexuous hairs on the corolla, the 
corolla-lobes are obtuse and the coronal-processes red.

spreading and ascending; margins reflexed. Column very small; anthers con- 
niving over the stigma, tips inappendiculate ; pollen-masses one in each cell,
