62 xcv. ASCLEPIADE.E. (J. D. Hooker.) \_Hoya. 



petiole \-\ in. Peduncles i-f in.; pedicels l-l in. Sepals shorter than the 

 corolla-tube. Corolla f in. diam., white. Coronal-processes (mutilated) as long as the 

 corolla-tube, apparently ovate, with the inner angle shortly spurred. The only 

 specimen I have seen is an unnamed one in Wight's Herbarium ; the plate in his 

 Icones is a copy of ^Roxburgh's drawing, which represents a much larger leaved plant 

 than the specimen. 



39. K. IVIaing-ayi, Hook.f. ; quite glabrous, leaves 7-8 in. elliptic-lan- 

 ceolate or oblanceolate finely acuminate very thick nerves reticulate distinct 

 very ojtdique, peduncle very short thick, pedicels longer, sepals small obtuse, 

 coronal-processes longer than the villous corolla-tube. 



MALACCA, Maingay (Kew Distrib. 1136). 



Stem stout. Leaves 2^3^ in. diam. at or above the middle, reticulate on both 

 surfaces, base narrow; petiole - in., very thick. Peduncle -1 in., thickened and 

 scarred ; pedicels 1 in. Corolla -f in. diam., pale pink, lobes short, obtuse. Coronal- 

 processes ovate, acute, narrow end outwards, above concave x with a mesial ridge, inner 

 angle apiculate shorter than the anther-tip. 



DOUBTFUL AND EXCLUDED SPECIES. 



H. CRASSIFOLIA, Haw. Succ. PI. Suppl. 8 ; Dene, in DC. Prodr. viii. 640. Scholera 

 crassifolia, Jacq. Eclog. t. 2 ; Traill. in Trans. Hort. Soc. vii. 22 ; from India ; with 

 leaves described as excessively thick, obsoletely spotted, petals truncate or obtuse, is 

 unknown, Wight (Contrib. 38) refers it to the Chinese H. carnosa, Br., which name 

 it would supersede. 



H. FINLAYSONII, Wight Contrib. 38 ; Wall. Cat. 8166 ; Dene I. 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. Finlay son. 



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. NICOBARICA, Br. in Wight Contrib. 36 (note under H.pendula, W. & A.); Dene. 

 1. c. Nothing is known of this. 



H. OPPOSITA, Don Grard. Diet. iv. 128 (Sperlingia opposita, Vahl; Wight Contrib. 

 67), is H. Rumphii, Blume, a Moluccan plant. 



H. WALLICHIANA, Dene. I.e. 635; said to be mixed with Wallich's n. 8165 (H. 

 latifolia), appears from Decaisne's description to be H. coronaria, Bl. 



H. VERTICILLATA, G. Don Gard. Did. iv. (Sperlingia verticillata, Vahl. Skrivt. 

 Naturhist. Selsk. Kiobenh. vi. 113), said to be a native of India, is unknown to me. 



H. SP. ? 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. 



45. PHYSOSTELMA, Wight. 



A twining glabrous shrub. Leaves opposite, coriaceous, shining. Flowers

 Coronal-processes 5, very large, ovoid-oblong, obtuse, aclnate to the anthers, 

 spreading and ascending ; margins reflexed. Column very small ; anthers con- 

 niving over the stigma, tips inappendiculate ; pollen-masses one in each cell, 

 ovoid-oblong, erect. Stigma flat. Follicles long, cylindric, smooth. Seeds
