320 SPECIES BLANCOANAE 
glandulosa Blanco to P. minor Andr., a manifest error. The 
form described by Blanco is clearly identical with the ones 
otherwise described by him as Pergularia procumbens and as 
Cynanchum hirtum. 
As to the propriety of adopting the generic name Telosma 
there can be no doubt. Coville proposed the name in 1905 for 
Pergularia of authors, not of Linnaeus [Contr. U. S. Nat. Herb. 
9 (1905) 384], typifying the genus Jelosma by Pergularia odora- 
tissima Lour. Two years later N. E. Brown, not knowing of 
the publication of Coville’s generic name, for the same reason 
proposed the new generic name Prageluria [Kew Bull. (1907) 
325]. Pergularia of Linnaeus is the genus later described by 
R. Brown as Daemia (Doemia).

ASCLEPIADACEAE OF UNCERTAIN STATUS 
Cylixylon heterophyllum Llanos Frag. Pl. Filip. (1851) 59 (heterophillum) 
(gen. et sp. nov.); F.-Vill. & Naves in Blanco Fl. Filip. ed. 3, 47 
(1880) 42—Asclepiadaceae indet. 
Fernandez-Villar reduced this to Gymnanthera pedunculata 
(Miq.) F.-Vill., a species that is definitely known in the 
Philippines only from Mindanao, and one to which Llanos’s 
description does not well apply. Llanos’s specimens were from 
Balatong and Pulilan, Bulacan Province, Luzon, and I have not 
been able to refer the form described to any known genus and 
species of the family; the species is not represented among the 
specimens sent by Llanos to the de Candolle herbarium. 
CONVOLVULACEAE 
EVOLVULUS Linnaeus 
Evolvulus linifolius Linn.; Blanco Fl. Filip. (1837) 221, ed. 2 (1845) 156, 
ed. 3, 1 (1877) 279-= EVOLVULUS ALSINOIDES Linn. 
This species is widely distributed in the Philippines but is of 
local occurrence. It grows in open grassy places at low and — 
medium altitudes, usually in poor soil that becomes thoroughly 
dry in the dry season. 
Illustrative specimen from Manila, Luzon, October, 1914 (Mer- 
rill: Species Blancoanae No. 137). 
PORANA Burman 
PORANA VOLUBILIS Burm, f.; Blanco FI. Filip. (1887) 88; ed. 2 (1845) 
64; ed. 3, 1 (1877) 119. 
Burman’s species was apparently correctly interpreted by
