19, 3 Merrill: Burman’s Flora Indica 373 
The data given by Burman and the distinctly good figure 
clearly indicate that his species is the same as Pergularia odora- 
tissima Sm. It is to be noted that the Javanese name malatti 
tonquin, cited by Burman from Kleinhof, is still used in Java 
for this species, being given by Koorders as malati tungking. 
The species is a native of southeastern Asia and, as the native 
name indicates, is an introduced one in Java; it is in general 
cultivation in the Indo-Malayan region for its very fragrant 
flowers. I do not consider Pergularia minor Andr. to be other 
than a synonym of P. cordata (Burm. f.) Merr. The generic 
name Pergularia of Linnaeus is the proper one for the African 
species long placed in Daemia. Prageluria N. E. Br. (1907) 
is a synonym of Telosma. 
TYLOPHORA R. Brown 
TYLOPHORA INDICA (Burm. f.) comb. nov. 
Cynanchum indicum Burm. f. Fl. Ind. (1768) 70. “Narin-talie. Ja- 
vanis. D. Outgaerden e Coromandel.” 
Asclepias asthmatica Linn. f. Suppl. (1781) 171. 
Tylophora asthmatica Wight & Arn. in Wight Contrib. (1834) 51. 
This is clearly the species commonly known as Tylophora 
asthmatica (Linn. f.) W. & A., as Hooker f. Fl. Brit. Ind. 4 
(1883) 45 cites “Cynanchum indicum Herb. Burm.” as a synonym 
of 7’. asthmatica W. & A. Burman’s specific name is the oldest 
valid one for the species and should be adopted. 
ASCLEPIADACEAE OF UNCERTAIN STATUS 
* PERIPLOCA DUBIA Burm. f. Fl. Ind. (1768) 70. “Habitat in Java & 
Malabara.” 
This has been reduced to Cryptolepis buchanani R. & S., but 
it is evident that two species are involved. The reference to 
Katu pal-valli Rheede Hort. Malabar. 9: 15, t. 11, belongs with. 
the Indian Cryptolepis buchanani R. & S. The Javan reference 
“Paepe-sajor. Javanis. D. Kleinhof” apparently typifies Bur- 
man’s species, but the description is altogether too short to 
warrant a reduction of it from the description alone. 
CONVOLVULACEAE 
PORANIA Burman f. 
PORANIA VOLUBILIS Burm. f. Fl. Ind. (1768) 51, t. 21, f. 1. “Habitat 
in Java.” 
A well-known species of wide distribution in southeastern 
Asia and Malaysia; the type of the genus.
