314 SPECIES BLANCOANAE 
Philippines. Accordingly the new name Parsonsia confusa 
Merr. was proposed for the Philippine form described by Blanco, 
his specific name being invalidated in the genus by Parsonsia 
spiralis Wall. It is not entirely certain that Parsonsia confusa 
Merr. is really distinct from Parsonsia cumingii A. DC., a very 
- similar, and at least a very closely allied species, also based on 
Philippine material.

ASCLEPIADACEAE 
FINLAYSONIA Wallich 
Tabernaemontana cirrhosa Blanco FI. Filip. (1837) 115 (sp. nov.); ed, 2 
(1845) 83; ed. 3, 1 (1877) 152=FINLAYSONIA OBOVATA Wall. 
This was reduced by Fernandez-Villar to Finlaysonia obovata 
Wall., which is certainly the correct disposition of it. I formerly 
considered this reduction to be an erroneous one, chiefly for the 
reason that Wallich’s species was then unknown from the 
Philippines, but I am now convinced that it is correct. Finlay- 
sonia obovata Wall. is now known from several localities in the 
Philippines, always growing in the mangrove swamps, and 
Blanco’s description of Tabernaemontana cirrhosa conforms 
closely to it. 
STREPTOCAULON Wight & Arnott 
Periploca calumpitensis Llanos Fragm. Pl. Filip. (1851) 62 (sp. nov.) ; 
Blanco Fl. Filip. ed. 3, 4‘ (1880) 47, t. 188=STREPTOCAULON 
BAUMII! Dene. 
This species is common and widely distributed in central and 
northern Luzon and in Mindoro, at low and medium altitudes. 
Fernandez-Villar was certainly correct in making this reduction, 
as Llanos’s description applies unmistakably to Decaisne’s 
species. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 168). 
ASCLEPIAS Linnaeus 
* Asclepias syriaca Blanco Fl. Filip. (1837) 204 (siriaca); ed. 2 (1845) 144; | 
ed. 3, 1 (1877) 261, ¢t. 71, non Linn. =ASCLEPIAS CURASSAVICA 
Linn. 
This species, originating in tropical America, was introduced _ 
into the Philippines at an early date and is now common and 
widely distributed in the settled areas at low altitudes through- 
out the Archipelago. It is our only representative of the genus. — 
Illustrative specimen from Batangas Province, Luzon, August, : 
1914 (Merrill: Species Blancoanae No. 83).
