relied on by Mr. Brown to keep separate the Aadepiadew 

 from the Apocynece to be, that the pollen in the former is ap- 

 plied to the stigma by an indirect and intermediate process, 

 while in the latter it reaches its destination directly and of 

 itself; circumstances associated to a proportionate influence 

 upon the general habit of the two orders. 



The present genus is remarkable for 5 glandular spoon- 

 like processes placed at the angles of the stigma, in which 

 the pollen is deposited previous to its arrival .at its ultimate 

 destination; a character that brings the genus within the 

 confines of the order where it now stands. 



The drawing was made from a specimen sent us by the 

 kindness of Sir Abraham Hume, by whom the plant is cul- 

 tivated in the hothouse at Wormleybury, where it flowered 

 last summer, we believe, for the first time in Europe. In 

 the Botanic Garden at Calcutta, it is said to be in blossom 

 through most of the year, but rarely to seed. The follow- 

 ing is Dr. Roxburgh's description of the plant. 



" Stem erect and woody: bark smooth, greenish aslw 

 colour: branches twining up and over trees of very consider- 

 able size, every part abundantly milky when wounded. 

 Leaves opposite, short-petioled, oblong, entire, obtuse, 

 pointed, polished on both sides, underneath minutely netted, 

 about 3 inches long by lj broad. Flowers terminal, from 

 one to many, forming a dichotomous raceme with one in 

 the fork, very large, pale pink. Bractes conically lanceo- 

 late, opposite, caducous. Calyx five-leaved : leaflets ovate- 

 lanceolate, with ample thin curled margins. Corolla cam- 

 panulate, half five-cleft. Scales 5 attached to the tube of 

 the corolla, immediately above the stamens, each divided 

 into long filiform coloured segments. Filaments short, in- 

 serted in the contracted base of the corolla: anthers cordate, 

 Incurved in the form of a dome over the stigma. Germens 

 2, 1-ceUed, each containing many ovula, attached to a 

 large projecting fleshy receptacle on the inside: styles 2 at 

 the base, coalescing near the top : stigma single, large, glo- 

 bular, bifid at the apex, with 5 glands round its sides which 

 are firmly attached to the inside of the 5 anthers, near their 

 base* between these are 5 dark-coloured spear-shaped scales, 

 which become detached by age." 



The name was suggested to Mr. Brown by the circum- 

 stance of the enclosure of the five-scaled crown within the 

 tube of the corolla, and its not being exposed to view as in 

 other bordering genera.
