20 Descriptions of Plants belonging to the Genus Hoya. 



above dark green, without apparent veins, except on the 

 young leaves where they may be occasionally observed on 

 the upper surface of a dark colour ; the whole of the leaves 

 are irregularly blotched or mottled above with spots of a 

 whitish-green colour. The petioles vary from one inch to 

 one inch and a half in length, at first they are of a dark 

 purple colour, but as they become older they assume the 

 same hue as the branches. The umbels are semi-globose. 

 The flowers are extremely beautiful and fragrant, flesh-co- 

 loured, frequently mottled with purple at the back, downy 

 within ; the segments are rather obtuse, with the sides and 

 ends folded back. The crown is purple in its centre. 



Of the three figures above referred to, viz. those of Sims, 

 Smith, and Jacquin, though all have much merit, that in 

 the Exotic Botany affords the best representation of the 

 plant, this figure was copied in 1810, into the German 

 Gardener's Magazine, No. 9, tab. 2. It appears from Steudel's 

 Nomenclator Botanicus, that this plant has been named 

 Schollia carnosa by Schrank, but I have not been able to 

 ascertain in what publication, so that the synonym is noted 

 without a reference. 



Loureiro's Stapelia Chinensis was referred to this species 

 by Mr. Robert Brown, in his Essay in the Wernerian Trans- 

 actions above quoted, on the authority of a specimen from 

 Loureiro's Herbarium, now in the Banksian Collection. 

 This specimen consists of a branch with leaves, and a few 

 separate flowers, it is ticketed Stapelia Cochinchinensis, and is 

 the only specimen referable to Hoya, received from Loureiro. 

 Loureiro has two Stapelias in his Flora Cochinchinensis,*
