MALVACEAE. 
MISCELLANEOUS SPECIES. 
Gaya violacea Rose, sp. nov. 
A slender erect shrub up to 2 meters high, the branches clothed with short soft 
pubescence together with long spreading hairs; petioles 4 to 6 cm. long; blade ovate, 
acuminate, coarsely crenate, cordate at base, the sinus either narrow or closed, 
becoming glabrate above, finely stellate-pubescent beneath; peduncles slender, a 
little shorter than the petioles, pilose as wellas stellate-pubescent; calyx lobes ovate, 
acute; petals violet; carpels 9, each one-seeded. 
Collected by C. G. Pringle under dry cliffs on the Sierra Madre above Monterey, 
1906 (no, 10221). 
Type in U. 8. National Herbarium no. 462260. 
This species is not very near any of the known Mexican species of Gaya, differing 
from them all in its violet or purplish flowers. 
Malvastrum“ bicuspidatum (S. Wats.) Rose. 
Malvastrum tricuspidatum bicuspidatum S. Wats. Proc, Am. Acad. 21: 417, 1886. 
In 1885 Dr. 8. Watson briefly described his variety bicuspidatum of Malvastriin 
tricuspidatum, which Mr. FE. G. Baker later referred to Malvastrum seabrum, to which 
it is much more closely related. In the National Herbarium we have considerable 
material labeled M. scabruim besides the Wilkes specimen from Peru, which appears 
to be true M. scabrum. A careful study of the Mexican species convinces me that the 
supposed variety deserves specific rank. It differs from JM. seabrum in its smaller 
leaves, these never cordate but cuneate at base, the flowers always solitary, the 
peduncles shorter, the sepals more acuminate, the carpels also slightly different. 
The following specimens have recently been collected: 
Morelos: Near Cuernavaca, Rose & Painter, September, 1905 (no. 10246). 
Guanajuato: Leon, Rose & Lozano, September, 1906. 
Wissadula microcalyx Rose, sp. nov. 
Stems herbaceous, | to 2 meters high, much branched, clothed with yellow glan- 
dular spreading hairs; leaves broadly ovate, sometimes 3-lobed, the lower ones 15 
em. long, acuminate, crenately toothed, cordate at base, stellate-pubescent beneath, 
inflorescence paniculate; calyx small, the lobes broadly ovate; corolla deep yellow, 
3 cm. in diameter; carpels obtuse, 3-seeded. 
Collected by J. N. Rose on the mountains west of Tehuacin, September 12, 1906 
(no, 11418). 
Type U.S. National Herbarium no, 454200. 
LOASACEAE. 
TWO NEW SPECIES OF EUCNIDE. 
Eucnida nelsonii Rose, sp. nov. 
Pubescence on stems soft and spreading; leaves all petiolate, nearly orbicular, 5 to 
60 mm. long, with rough pubescence on both surfaces, irregularly lobed and toothed; 
pedicels 2 mm. or less long; calyx lobes linear-oblong, | em. long; petals erect, 2.5 
mm. long; stamens numerous, longer than the petals. 
«Malvaeopsis C. Presl has priority over Malvastrum and accordingly has been sub- 
stituted for it by some writers. It is not at all clear to my mind that these two names 
belong to the same genus and I therefore propose provisionally to retain Malvastrum, 
The Vienna Congress has also retained this name, but for a different reason.
