ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 285 
TILIACEAE. 
. FOUR NEW SPECIES OF TRIUMFETTA. 
The genus Triumfetta has long been in need of revision, and some 
years ago I hoped to present a preliminary treatment of the Mex- 
ican species, but I have not been able to finish it. While trying to 
arrange the Mexican material in the National Herbarium I discovered 
the following new species: 
Triumfetta falcifera Rose, sp. nov. 
Low, bushy shrubs, 90 to 150 cm. high; branches densely pilose; leaves lanceolate, 
Jong-acuminate, rounded at base, 7 to 10 cm. long, with scattered simple and stellate 
hairs above, densely and softly stellate beneath; flowers in small axillary clusters 
or in narrow more or less elongated panicles; sepals densely pubescent, about 6 mm, 
long, the appendages 4 mm. long, often 2-parted, sometimes 3-toothed; petals yellow; 
stamens indefinite; fruit orbicular, covered with stout short prickles, nearly glabrous, 
4-celled. 
Collected by Dr. FE. Palmer near Acapulco in 1894-95 (nos. 63 & 266). 
Type U.S. National Herbarium no. 266324. 
Triumfetta dehiscens Rose, sp. nov. 
Stems shrubby; young branches with dense reddish stellate pubescence; upper 
leaves short-petioled, lanceolate, acuminate, very irregularly serrate, the lower teeth 
glandular, the young ones very pale beneath, densely soft-stellate, greener and less 
stellate above; fruit orbicular, covered with short glabrous prickles, 5-celled, dehis- 
cing when mature. 
Collected by J. N. Rose near Colomas, July 16, 1897 (no. 1698). 
Type U.S. National Herbarium no. 300559. 
Very different from most species of the genus, which have indehiscent fruit. 
Triumfetta discolor Rose, sp. nov. 
Plants growing in clumps, 60 to 90 em. high; branches pubescent with fine hairs 
interspersed with coarse stellate or simple pilose ones; leaves with petioles about the 
length of the blade, the blade nearly orbicular in outline and obtuse, rarely ovate and 
acutish, 2 to7 cm. in diameter, greenish above with rough scattered stellate hairs, white 
beneath with a dense stellate tomentum; inflorescence terminal in a mostly naked 
narrow panicle; sepals 4 or 5, brownish, somewhat. stellate, the appendage slender 
(2 to3mm. long); petals bright yellow, about the length of the sepals, hairy at base; 
stamens about 20; fruit not seen. 
Collected by J. N. Rose between Pedro Paulo and San Blascito, Territorio de 
Tepic, August 4, 1897 (no. 1979 type), and on the east slope of the west range and the 
west slope of the east range of the Sierra Madre in the State of Durango, August 13 
and 15 (nos. 2255 and 3305). 
Type U.S. National Herbarium no. 300870. 
A very beautiful species which does not approach any other described from Mexico. 
T. socorrensis has somewhat smaller but thicker leaves. 
Triumfetta goldmanii Rose, sp. nov. 
Branches at first covered with small stellate hairs but soon becoming glabrate; 
leaves lanceolate, rounded at base, acuminate, green but with scattered simple, 
appressed hairs above, paler and somewhat more pubescent (hairs also simple) 
beneath, crenately toothed, 5 to 7 em. long; petioles short (in specimens seen), 1 
em. long; flowers usually in umbels of 2 or 3; peduncles 1 to 3 in the upper axils, 3 
to 4mm. long; pedicels 4 to 10 mm, long; calyx 15 to 16 mm. long, covered with 
small stellate hairs without and bearing a small erect appendage just below the tip; 
petals yellow; anthers reddish; ovary and fruit sessile; fruit glabrous but covered 
with stout bristles, somewhat rugose, globose, 5 mm. in diameter. 
Collected by E. A. Goldman on the Sierra de Choix, 50 miles northeast of the 
town of Choix, State of Sinaloa, October 17, 1898 (no. 264). 
Type U. 8. National Herbarium no. 335763.
