of 8-15 spk, which become spreading; spkt

"Culm 9-18 i hi, flattened below, 

 branching, Ify: lvs puberulent, especially 

 the inflated, conduplicate sheaths which 

 are ciliate on margins, and with a ligule 

 of rather lg w hairs; sheaths mostly as 

 lg as the internodes; blade lanceolate- 

 linear, 4-6 i lg. Spk consisting of 2 to 4, 

 com 3, large, roundish, closely approxi- 

 mate, p spikelets, 1-1% i in diam, in- 

 cluding the spines, these are flattened 

 toward the base, the upper part slender, 

 the long'st 6-8 lines long, diminishing to 

 the broad base, where a few are much 

 smaller, but there are no proper bristles. 

 The base of the spines and the body of 

 the spikelets are closely pubescent. Each 

 spikelet contains 5 or 6 flowers. First 

 collected by Dr. E. Palmer at Guaymas, 

 Mex., in 1887, in company with a y- col- 

 ored variety. The present specimens are 

 a young and small form, with the spkt 

 half as large as the type, but otherwise 

 the same. Possibly it may be a distinct 

 var. — Com thruout the southern part of 

 the peninsula." — Vasey in Br 2:211. 

 YUCCA VALIDA Br 2:208 t II. 



"Arborescent, 15-20 ft hi, trunks 8*4 

 to 2 ft or more in diam, growing in 

 cSumps and branching from near base or 

 higher: lvs thin, smooth, flexible,* 6-9 i 

 lg, Y2 to % i wide at center, tapering to 

 a stout involute spine above, and nar'ed 

 to less than half its width above the 

 brown, dilated base, margin separating 

 into slender, whitish, recurved threads; 

 panicle pyramidal, about a ft lg, some- 

 what pubescent: perianth cream -W,' 2-2% 

 i broad on pedicels nearly as lg as the'seg, 

 which are broadly lanceolate & nearly 

 equal in width: sta pappillose, less than % 

 as lg as seg, about equaling the sty, unci- 

 nate after maturity: anth sagittate; ova 

 oblg, abruptly nar'ed to the nearly sessile 

 stigma; ovules thick. This Yucca is cer- 

 tainly distinct from Y. baccata, and does 

 not seem referable to any of its Mexican 

 varieties. It does not begin to bloom un- 

 til about the middle of May, when Y. 

 baccata to the north of it, has already 

 nearly mature fr. It was observed from 

 San Jorge to San Borgia, and near Patro- 

 cinia formed forests miles in extent; the 

 trees in general appearance strikingly like 

 Y. brevifolia, though the trunks were 

 much less covered with old reflexed lvs."

AGAVE SOBRIA Br 2:207. 



"Euagave. Acaulescent: lvs about 20, 

 glau, lanceolate, about 2 ft lg, nar'ed from 

 panicle; branches 6-12, ascending, 6 in 

 lg or less, rather few-fld; fls light y; tri- 

 angular lobes 10-15 mm lg, a little exceed- 



ing tube: sta adnate to base of lobes, & 

 about twice their length: sty tubular, 3- 

 lobed, a little exceeding sta: cap some- 

 what clavate- trigonous, constricted near 

 middle, 30-50 mm lg, 8-12 wide: sds 3-4 

 mm in diam, smooth. Very abundant 

 upon Magdalena & S Margarita Islands, 

 but not seen upon the mainland. The fls 

 were filled to overflowing with nectar, 

 which was 6ft seen running down the 

 st.'^— Br 2:206.
