equal length and a staminate flower; fertile lemma subindurate, 5-nerved, the 
apex attenuate and spreading. 
Type in the U.S. National Herbarium, no. 1,152,018, collected in the crater 
of the voleano Cerro de la Olla near Chalchuapa, Salvador, in 1922, by Dr. 
Salvador Calder6én (no. 1049). 
This species is related to Pennisetum karwinskyi Schrad., from the high- 
lands of Mexico, from which it differs chiefly in its larger panicles, in its more 
numerous bristles, the inner plumose, and in the much longer innermost 
bristles. A second collection of this species, Jiménez 522, from Nuestro Amo, 
on the Pacific slope of Costa Rica, was referred to P. karwinskyi as an excep- 
tional specimen, in a recent revision of the genus.2. In this specimen the inner- 
most bristles are as much as 5 em. long, but the inner bristles are much less 
plumose than in the Salvador specimen. Like that, the plant is without the 
base. 
. Lindmania flaccida Standl., sp. nov. 
Plants terrestrial; leaves basal, few, very thin and soft, 25-30 em. long or 
larger, 3.5-4.5 em. wide, entire, slightly narrowed near the base, rather 
abruptly narrowed to a short subulate tip, glabrous above and slightly brown- 
spotted, beneath very sparsely stellate-lepidote; inflorescence about 50 cm. 
high, once-branched, the branches long and slender, about 10 cm. long, 
solitary or fasciculate, sparsely arachnoid-villous or glabrate, the bracts of 
the scape entire, thin, about equaling the nodes; flowers scarcely secund, 
nodding, the pedicels slender, about 3 mm. long, glabrous, the bractlets lance- 
ovate, scarious, much exceeding the pedicels and often equaling the sepals; 
sepals ovate, acute, about 3 mm. long, scarious, persistent; petals linear- 
lanceolate, eligulate, 7-8 mm. long, green, acute, conspicuously nerved; 
stamens shorter than the petals, the anthers linear-oblong, yellow, undulate, 
not contorted; ovary almost wholly superior, glabrous, the style long and 
slender, equaling or surpassing the stamens, the branches slender-clavate; 
seeds numerous, minute, dark brown, with a pale appendage at each end. 
Type in the U.S. National Herbarium, no. 1,135,666, collected on a moist 
shaded bank along a stream in the mountains near Ahuachapin, Salvador, 
January, 1922, by Paul C. Standley (no. 19786). 
The genus Lindmania has not been reported previously from Central 
America, the known species being natives of South America. The present 
plant may perhaps represent an undescribed genus, but it seems to agree 
moderately well in most of its characters with the plants heretofore referred 
to Lindmania. 
Tillandsia vicentina Standl., sp. nov. 
Plants solitary, epiphytic; leaves numerous, about 25-30 cm. long, equaling 
the inflorescence, thin, 3-5 mm. wide at the middle, the bases 1.5-2 em. 
wide, brownish, the blades green on the upper surface and covered with closely 
appressed scales, beneath silvery, covered with coarse loose whitish scales; 
scapes 15-25 cm. high, stout, covered with numerous overlapping bracts, 
these coarsely lepidote, their tips filiform-attenuate, their bases slightly 
inflated; spikes 5-11, simple, digitate or shortly pinnate, sessile, 4—7 cm. long,
