ALABASTRA. PHILIPPINENSIA, HI. 343 
_ With 4 sheets from Formosa for comparison, including two of the type collec- 
tion, Henry 1112, very constantly agreeing Mith one another, and the above 
cited Philippine specimens, differing regularly from them in various characters, 
I feel convinced that two distinct species are concerned. The. best character 
IS that of the fruiting calyx, but evefti by the leaves there is no dimcuUy in 
separating the two series. The flowers of the Philippine species are also larger, 
and those on the Formo^an plants are apparently mature. Rhamnu^ pulogensi.^ 
Men-., the other Philippine species of the genus, is very different. 
MALVACEAE. 
GOSSYPIUM Linn. 
Gossypium panicuiatum Blanco Fl. Filip. (1837) 539; ed. 2 (1845) 378. 
Blanco's description may be translated thus. Stem round. Leaves alternate, 
soft, villose, slightly heart-shaped, with 3 sharp lobes, the older leaves with 2 
other smaller lobes or also with 3 additional t^eth on each side, with 7 nerves, 
and a small gland on the lower surface of the costa. Petioles long, with 2 
awl-shaped stipules at the base. Flowers lateral and inclined to one side, in a 
kind of simple few-flowered panicle. Pedicel shorter than the flower. Calyx 
double, the outer of 3 heart-shaped parts, each with a gland at the base and 
10 or 11 long sharp teeth. Interior calyx smaller with 5 sharp lobes. Corolla 
campanulate, red or white, of 5 parts, larger than tlie outer calyx. Stamens 
many on a column. Stigmas 3 or 4. Capsule oval, sharp, 4-celIed. Seeds 
enveloped and strongly fastened together by the cotton. Height a little more 
or less than a vara {836 mm). Known and used in Ilocos, equal in quality to 
that of Batangas; nevertheless, the latter appears to be the stronger, with more 
lustre and body, and yet to attain the whiter color. From this cotton the 
lloeano women make cloth of exquisite fineness and appearance. It is distin- 
guished from that of Feraambuco {G. hrasilieiise Macfad.) by the inflorescence 
and other points .... Flowers in January. Local name (Ilocano) : capas. 
In order to ascertain the identity of Ilocos cotton, Mr. W. K. Weaver, of 
V'igan, Ilocos Sur, has obtained four plants from that place for our collections. 
The first question is whether they represent Blanco's species, and there ye 
difficulties. The bracteoles have 8 to 10 teeth, usually 9, the flowers are ilot 
in panicles, the capsules are 3-celled. Tlie last does not entirely contradict 
Blanco, as he says that the stigmas are 3 or 4. In other respects, the agreement 
is quite sufficient, the only other discrepancy being with the leaf-glands, which 
vary on the specimens. All things considered, it is highly probable that these 
can be identified as 0. panicuiatum Blanco. 
Following more modern systems of classification, the alliance proves to be 
with G. nanking Meyen. Tliere is a comjdete fuzz, the floss is white, the bracteoles 
are united at the base but only moderately, 2 to 3.5 mm out of a total length of 
3 cm; the leaves are definitely or slightly cordate, their lobes are 3 or on older 
leaves 5, not constricted at their bases, dividing the lamina for half its length, 
or more often less. Two of the plants were noted as white-flowered, a third as 
red-flowered, while the upper flowers of the fourth were white and the lower red. 
But they do not agree well with any of the varieties of Q. nanking enumerate! 
by Watt," diflFering from all of them in the bracteoles, probably approaching 
nearest to var. rubiminda. Blanco's species was apparently overlooked by Watt. 
If the bracteoles be considered insufficiently united for the section of the genus,
