MALVACEAE 253 
is found in and about towns throughout the settled areas in the 
Archipelago. The form described by Blanco as S. semicrenata, 
whether or not quite the same as Link’s species I cannot deter- 
mine, is exactly the form described by de Candolle as Sida philip- 
pica. I take it to be very typical Sida rhombifolia Linn. 
Illustrative specimen from Manila, Luzon, September, 1913 
(Merrill: Species Blancoanae No. 450). 
Sida lanceolata Retz.; Blanco Fl. Filip. (1837) 548=Sida frutescens Cav.; 
Blanco op. cit. ed. 2 (1845) 384; ed. 3, 2 (1879) 341, t. 366=SIDA 
ACUTA Burm. f. 
Blanco correctly interpreted both Sida lanceolata Retz. in the 
first edition and Sida frutescens Cav. in the second edition of 
his Flora de Filipinas, but Burman’s name is much the older, 
dating from 1768; Sida carpinifolia Linn. f. (1781) is a synonym. 
It is very common in waste places in and about towns through- 
out the Philippines at low and medium altitudes and is certainly 
not a native of the Archipelago but an introduced weed. There 
is no indication that Blanco intended his Sida lanceolata as 
Retzius’s species, but this is presumably the case as he likewise 
does not indicate it as a new species. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No, 457). 
MALACHRA Linnaeus 
Napaea latifolia Blanco Fl. Filip. ed. 2 (1845) 387 (sp. nov.); ed. 3, 2 
(1879) 846, t. 295—=MALACHRA CAPITATA Linn. 
A common and widely distributed weed in the Philippines, 
occurring in the settled areas at low altitudes. Introduced from 
Mexico at an early date.

Napaea scabra Blanco FI. Filip. (1837) 553; ed. 2 (1845) 386; ed. 3, 2

loba Turcz., type from the Philippines, Malachra fasciata Jacq., var. 
lineariloba Girke). 
Common and widely distributed in the Philippines at low alti- 
tudes in the settled areas, introduced from Mexico at an early 
date.
