Hygrophila salicifolia Nees.

Ruellia uliginosa Blanco FI. Filip. (1837) 494; ed. 2 (1845) 346; ed. 3, 2 
(1878) 277, non Linn. f.=BLECHUM BROWNEI Juss. 
This species of American origin is now widely distributed in 
_ the settled areas of the Philippines at low altitudes. It is also 
common in Guam and has extended to Formosa. It was un- 
doubtedly introduced into Guam and into the Philippines 
througin the medium of the Acapulco-Manila galleons.

HEMIGRAPHIS Nees 
Ruellia repens Blanco Fi, Filip. (1837) 493; ed. 2 (1845) 345; ed. 3, 2 
(1878) 276, non Linn. =HEMIGRAPHIS STRIGOSA (Nees) F.-Vill. 
(H. repens F.-Vill.). 
Fernandez-Villar considered that Blanco’s Ruellia repens 
represented a valid species of Hemigraphis, which he called H. 
repens (Blanco) F.-Vill. I can see no reason for considering 
the form Blanco described to be other than the widely distrib- 
uted Hemigraphis strigosa (Nees) F.-Vill., which was origin- 
ally described from Philippine specimens, and from which 
Hemigraphis lanceolata Clarke is probably not specifically dis- 
tinct. Blanco’s specimens were from Cebu. 
LEPIDAGATHIS Willdenow 
Ruellia secunda Blanco FI. Filip. (1837) 495 (sp. nov.); ed. 2 (1845) 346; 
ed. 8, 2 (1878) 278=LEPIDAGATHIS SEGUNDA (Blanco) Nees. 
Lepidagathis secunda Nees was based on Ruellia secunda 
_ Blanco, the description amplified by reference to Cuming 581 
from Calauan, Laguna Province, Luzon. Blanco’s specimens 
were from Pasig, Mandaloyon, and Santiago Point. It is the 
only species of the genus known to occur in the immediate 
vicinity of Manila and is to-day fairly abundant on some parts 
of the Mandaloyon estate and in Pasig. Lepidagathis luzona 
_ Nees is apparently identical with L. secunda Nees. 
Illustrative specimen from Angat, Bulacan Province, Luzon,
