320 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
2em. broad; staminal tube very short; carpels 7 mm. long, obtuse with thin reticu- 
lated walls. 
Collected by H. von Turckheim at Coban, Department of Alto Verapaz, Guatemala, 
altitude 1,300 meters, November, 1902 (J. D. Smith’s no. 8382). 
Nearest, PR. divergens, but with less densely stellate branches, leaves with entire 
margins, shorter staminal tube, less densely pubescent ovaries, much smaller carpels, 
and pilose pedicels. 
Robinsonella pilosa Rose, sp. nov. 
Differs from the above in having the base of the blades not lobed, the older 
leaves glabrate, the pedicels more pilose, and the buds very densely pilose. 
Collected by Gustavo Neiderleim in the Comayagua between the villages of Flores 
and Comayagua, Honduras, February 22, 1898. 
BOMBACEAE. 
TWO NEW SPECIES OF CEIBA AND A NEW NAME. 
Ceiba pallida Rose, sp. nov. 
A large tree; young branches either glabrous and glaucous or more or less densely 
pubescent; leaves long-petioled; leaflets 5 to 7, oblanceolate, cuneate into a short 
petiolule, long-acuminate, slightly pubescent (hairs simple) on both sides, very pale 
beneath, sharply and closely serrate, the teeth usually spreading; flowers very large; 
calyx large and broad, 2 to2.5 em. long, nearly as broad at mouth, the lobes appar- 
ently deciduous giving a somewhat 5-lobed calyx tube, glabrous and glaucous without, 
densely reddish-pubescent within; petals 12 to 14 em. long, 2 em. broad, densely 
covered without with long brownish silky hairs; stamen tube 2 mm. long, densely 
brownish-lanate; free part of filaments alternating with small brownish seales, 7 to 8 
em. long, glabrous, much shorter than the petals; style glabrous. 
Collected by J. N. Rose and Walter Hough near Cuernavaca, May 27 to 30, 1899 
(no. 4357, type) and by C. G. Pringle from the same tree, May 31, 1899 (no. 8212), 
With these I have tentatively placed Rose and Hough’s plant (no. 4564) from Tomel- 
lin Canyon, Oaxaca, although it is without flowers or fruit. This species is nearest 
the Yucatan plant (. cesculifolia, but with different serrations to the leaves, ete. — It 
differs from the northern species C. tomentosa and C. aeummata in the simple hairs 
of its pubescence. 
Ceiba parvifolia Rose, sp. nov. 
A tree 6 meters high with a broad spreading top; old branches reddish and 
smooth; young branches somewhat reddish-pubescent; leaflets 5, small, 3 to 5 em. 
long, obovate, narrowly cuneate at base into a slender petiole, rounded at apex 
except for an abrupt apiculation, more or less stellate on both sides but soon becom- 
ing glabrate, sightly paler beneath. 
Collected by the writer on the dry hills near the little town of Matamoras, Puebla, 
June 26, 1899 (no, 4701). Unfortunately no flowers were obtained, but a photograph 
was taken which shows well the habit. 
Perhaps with this species is to be associated my no. 4670 from Tomellin Canyon, 
The leaflets, however, are more pubescent and only a little or not at all apiculate. 
Palmer's no. 603 from Acapulco is also somewhat simular, but the leaflets are glab- 
rous. Rose and Painter's no. 6564 from Yautepee probably belongs here, but the 
leaflets are perfectly glabrous. 
Ceiba acuminata (8. Wats.) Rose. 
FEriodendron acuminata 8S. Wats. Proe. Am. Acad. 21: 418. 1886. 
Type locality, ‘‘ Hacienda San Miquel,’’ Chihuahua; collected by Dr. FE. Palmer. 
This species is only known from the type collection and has never been collected 
in flower, It must be near C. fomenfosa and with the material in hand it is difficult 
to separate them, The flowers may show some good specific differences.
