NOTES ON PHILIPPINE BOTANY.

Peninsula. The plant from Siam seems to be not “Russeliana,” but 8 . australis 
which is widely diffused throughout the Malayan and Pacific regions, and to 
which the Philippine specimens mentioned above must be referred. ( J. E. D.) 
SENECIO Linn. 
Senecio luzoniensis Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 244. 
This is evidently an endemic species representing the series of forms usually 
placed under 8. sarracenicus or S. nemorensis, which extend from central and 
southeastern Europe through northern China to western China. The Luzon form 
is sufficiently distinguished from Chinese 8. nemorensis by the sharper angles at 
which the secondary nerves of the leaf are given off from the midrib and then- 
far shallower curvature. (J. R. D.) 
GYNURA Cass. 
Gynura rubiginosa (Elmer) J. R. Drummond comb. nov. 
Senecio rubiginosus Elmer Lead. Philip. Bot. 1 (1906) 154. 
Luzon, Province of Benguet, Mount Santo Tomas, Elmer 6246. 
I cannot see how this plant can be generieally separated from Gynura Vida- 
liana Elmer, which belongs to. a characteristic Indonesia group of closely allied 
forms. (J. E. D.) 
Gynura Vidaliana Elmer Leaf!. Philip. Bot. 1 (1906) 144. 
Luzon, Tidal 11/99, 1510, 3135 ; Loher 3697, 3701, 3702; Mieholitz s. n. ; Merrill 
4593, 4844. 
These apparently represent a single, rather variable species, but more material 
is needed to dispose of Merrill 3937 from Mount Arayat, which appears possibly 
to be distinct. However it is possible that this species, with G. purpurascens 
DC., G. aurantiaca DC., possibly also G. nepalensis DC., and G. Finlay soniana, 
constitute but forms of the officinal G. Pseudo-China DC. ( J. R. D.) 
Gynura sarmentosa DC. Prodr. 6 (1837) 298; F.-Vill. Nov. App. (1883)

Gynura affinis Turcz. in Bull. Soc. Nat. Mosc. 24 1 (1851) 201; F.-Vill. 1. c. 
120 . 
Gynura scabra Turcz. 1. c. 
Senecio mind orensis Elmer Leafl. Philip. Bot. 1 (1906) 155. 
This widely distributed species is well represented in the Ivew herbarium, and 
we are of the opinion that the two species described by Turczaninow, based on 
Cuming’s material, as well as Senecio mindorensis Elmer, are all referable to 
typical Gynura sarmentosa DC. We have not been able to identify the plant 
collected by Copeland, no. 1258, which was referred by Elmer, 1. c. 147 to 
DeCandolle’s species, and it is possibly not a Gynura.
