Burman’s binomial typifies the species. It is more commonly 
known as Strophanthus dichotomus DC., and extends from 
Burma and Indo-China to Malaysia. Neriuwm scandens Lour. FI. 
Cochinch. (1790) 116 = Strophanthus scandens R. & S. Syst. 
4 (1819) 412 does not appear to be specifically distinct. 
VALLARIS Burman f. 
VALLARIS GLABRA (Linn.) O. Kuntze Rev. Gen. Pl. (1891) 417. 
Pergularia glabra Linn. Mant. 1 (1767) 53. 
Vallaris pergulanus Burm. f. Fl. Ind. (1768) 51. “Habitat in Java.” 
Emericia pergularia Roem. & Schultes Syst. 4 (1819) 401. 
Burman’s specific name should be retained for this well-known 
Species. Flos pergulanus Rumph. Herb. Amb. 5: 51, t. 29, f. 2, 
isa synonym. It is probable that both Burman’s and Linnaeus’s 
descriptions were based on material of similar origin. 
APOCYNACEAE OF DOUBTFUL STATUS 
* APOCYNUM VINCAEFOLIUM Burm. f. FI. Ind. (1768) 71. 
The references are to “Asclepias javanica angustifolia Garzin. : 
herb.” and to an illustration of an American plant in Plukenet 
Alm. 35, t. 260, f. 14. It is clear that the two are neither con- 
specific nor congeneric. The short description is based on the 
Javan plant, but there are no data by which its identity can 
be safely determined; it is clearly no Apocynum. : 
* ECHITES NUMMULARIA Burm. f. Fl. Ind. (1768) 69, t. 28, f.1. “Hab- 
itat in India.” 
I do not recognize the species figured; it is, however, distinct- 
ly characteristic. The citations to pre-Linnean literature added 
by Burman probably all represent species different from the 
one figured and described by him. It probably represents some 
apocynaceous plant. 
* JASMINUM OBLONGUM Burm. f. FI. Ind. (1768) 6, t. 8, f. 2. “Habitat 
in Java.” 
This was described and figured from Javan material ‘it 
manifestly no Jasminum, but probably represents some apocyna-~* 
ceous plant.
