Trelease—The Agaveae of Guatemala. 137 
AGAVE SEEMANNIANA Jacobi. 
Agave Seemanni Bull, List. 22:3. 1867; also 34:26, 45:18, 49:23. 
No doubt too incompletely characterized to fix this spelling of the 
name, which nevertheless is still well established in gardens—e. g. 
Finckh, Gard. 51: 407. f. (1897). 
A. Seemanniana, Jacobi, Ablandl. Schles. Geselisch. 1869: 154. 
Acaulescent, not cespitose. Leaves glaucous, some- 
what green-banded, openly spreading, oblanceolate-ob- 
long or obovate, acute or subacuminate, minutely rough- 
ened toward the apex, 835 cm.; spine purplish brown, 
somewhat glossy above, minutely granular below, slen- 
derly conical or acicular, more or less flexuous, involutely 
grooved from above the middle with acute edges, decur- 
rent for its own length or less, scarcely intruded into the 
green tissue, 2-4 20-30 mm.: teeth brown or turning 
gray, 10-20 mm. apart, 2-3 mm. long, rather straight 
but the lower pointing downwards, the slenderly trian- 
gular cusps abruptly dilated onto the tops of fleshy 
prominences between which the somewhat concave mar- 
gin sometimes bears slender dark denticles. Inflores- 
cence said by the collector to be 2 m. high. From the 
illustration of a specimen flowering in Sydney, N.S. W., 
the inflorescence is 5 m. high, the oblong panicle with 
densely bunched flowers occupying three-fourths of its 
length, and the short scape with broad bracts. 
Specimens examined: Guatemaua. Fiseal (Deam, 
6154, June, 1909). Without data, living plants (Mis- 
souri Botanical Garden, 1887; Kew, no. 271/97, 1905). 
A specimen with the spine-base heavier than usual, but 
referred here, occurs without data in the herbarium of 
the Missouri Botanical Garden (Norton, 2, Feb., 1912), 
and may be ealled var. perscabra. 
That A. Seemanniana may have been introduced into 
cultivation in the form of plants as well as seeds is sug- 
gested by Ellemeet’s!® reporting soon after its introduc- 
15 Belgique Horticole. 1871: 118.
