156 PROCEEDINGS OP THE AMERICAN ACADEMY 



anth yellow, the segments oblong, obtuse, 9 lines long by 3 broad, 

 faintly nerved except toward the base: free portion of filament nearly 

 2 lines long ; style cleft nearly to the base. — In the barranca near 

 Guadalajara; July, 1889 (n. 287G). Resembling S. Arizomcum, but 

 more glabrous, the broader leaves less acuminate, and the style more 

 deeply cleft; fruit unknown. 



Agave (Litt^a?) Hartmani. Acaulescent; leaves very numer- 

 ous in a dense rosette (becoming a foot in diameter), broadly linear 

 above the short dilated base, the blade 3 inches long by about |- inch 

 broad, very thick, convex on the back, marked on both sides by broad 

 intersecting gray lines (as in A. ^lif era), ending abruptly in a stout 

 brown spine 2 or 3 lines long, the margins at base acute and finelj' 

 serrulate, obtuse above and bearing on each side about half a dozen 

 very slender recurved ash-gray threads : flowers and fruit unknown. — 

 Collected by Mr. C. V. Hartraan, botanist of the Leraholtz expedition, 

 and in cultivation at the Cambridge Botanic Garden. 



Agave (Manfreda) brunnea. Acaulescent: leaves rather few, 

 fleshy, recurved, channelled above, 4 inches long or less by 6 to 10 lines 

 broad in the middle, the margin armed with scattered broad hooked 

 spines a line long: flowering stem 2 feet high, with lanceolate narrowly 

 attenuate bracts shorter than the nodes : flowers few (about 6), ses- 

 sile ; ovary 6 lines long; perianth 15 to 18 lines long, the narrow tube 

 nearly twice longer than the dark brown narrowly oblong spreading 

 lobes : stamens and style much exserted : capsule broadly ellipsoidal, 

 about 9 lines long. — On the battle-field of Buena Vista, Tamaulipas ; 

 July, 1888 (n. 2218). 



EciiEANDiA NODOSA. Roots coarsely fibrous ; the base of the plant 

 surrounded by the more or less fibrous remains of numerous dead 

 leaves : leaves broadly linear, 18 inches long by 12 to 1 ") lines broad, 

 attenuate to each end, very shortly ciliolate : stem 3 feet high, panicu- 

 lately branched, the branches spreading and very slender with numer- 

 ous nodes (mostly approximate, 3 to 6 lines apart, sometimes more 

 distant) ; pedicels very slender, 3 to 6 lines long, jointed a little below 

 the middle: perianth pale yellow, 5 lines long: capsule broadly ellip- 

 tical, 2 or 3 lines long. — In the barranca near Guadalajara; Nov., 

 1888 (n. 2151). This genus must include several species, though it is 

 difficult to identify the forms that have been described as distinct, and 

 which have of late all been embraced under 7i'. ternijlora. A form 

 more nearly resembling typical E. ternl flora is Mr. Pringle's n. 3183 

 of 1890. This has long and more or less tuberous-thickened "oots, 

 and linear-lanceolate leaves attenuate from near the base to (^ nar-
