BNGELMANN — NOTES ON AGAVE. 331 



and curved downwards. The leaf of the wild plant, now before 

 me, is S inches long and 4 wide, terminal spine very stout, lo-ii 

 lines long, decurrent about the same distance ; arrangement of 

 marginal teeth quite peculiar, the uppermost ones the largest, 

 ij-3i lines long from a broader base, straight, almost bladk and 

 very rigid, 6-8 lines apart ; teeth below the upper third smaller 

 and closer set, and below the middle only 3-3 lines apart, less 

 than I or only h line long and strongly curved downwards. 

 Scape 13 feet high, branches of the panicle loosely ramified, 

 branchlets 3-6 inches long, pedicels i-3 lines long ; flowers in 

 small clusters, 3-6 or 8 together, 3} inches long, perigon half as 

 long, divided to the middle ; stamens inserted about f from the 

 base of tube, exsert about I inch above lobes ; anthers lo-ioi 

 lines long. Capsule 18-33 lines long, 7-8 wide, similar to that 

 of last species but not stipitate ; seeds 3| lines in diameter, cells 

 of the surface, under the microscope, flat, punctulate. 



I have a flower and a capsule of Agaves differing from anv 

 above described, and thus perhaps indicating two other species ; 

 but as the material is too incomplete to characterize them, I only 

 indicate them here for further investigation. 



Agave sp. " Common on mountain-sides in the Wild Rose 

 Pass on the Limpio," West Texas, Chas. Wright, No. 1906 ; 

 flowers only, collected June 11, 1851, referred by Torrey in Bot. 

 Bound. 313 to A. Americana. Flower not quite 3 inches long, 

 perigon equal to ovary, divided to the middle ; stamens inserted 

 about t up the funnel-shaped tube, reaching 14 lines above the 

 lobes; anthers 10 lines long, — Could it belong to the last de- 

 scribed species, which was found 300 miles further south? 



Agave sp. Dragoon Mountains, Southeastern Arizona, Capt. 

 Chas. Bendire, U. S. A. A capsule and seeds only, with the 

 verbal information that the leaves are about 3 feet long and 4 

 inches wide, and the scape nearly 30 feet high. The capsule is 

 ovate-prismatic, 3 inches long, 10 lines wide, strongly cuspidate, 

 at base obtuse; seeds 3J lines in longest diameter, apparently 

 minutely pitted. — It is not probable that this could be a form of 

 A. Americana^ as that species has, I believe, always a stipitate 

 capsule and larger seeds with flat, punctulate areae.
