GREENMAN, — NEW ANGIOSPERMS FROM MEXICO. 73 
altitude 2130 to 2285 m., 23-31 August, 1898, Z. W. Nelson, no. 4844 
(hb. U. S. Nat. Mus., and hb. Gr.). 
Anthericum Nelsonii is apparently most nearly related to A, nanum, 
Baker, from which it differs in the glabrous character of the scape and 
by the twice longer capsule. 
Echeandia flexuosa. loots fascicled, tuberous, crowned by a 
collar 6 em. in length, the persistent fibres of the bases of the older 
leaves: scape 7 to 9 dm. high, flexuous, glabrous, leafy at the base, 
bearing one or two reduced leaves on the main axis, few-branched above 
into arcuate-ascending more or less flexuous and somewhat compressed 
or subangulate branches: leaves linear-attenuate, 1.5 to 8 dm. long, 
2to5 mm. broad, ciliolate to slightly roughened along the margins, 
thickish and firm in texture, closely parallel-nerved, without transverse 
anastomosing veinlets, glabrous above, scabrellous on the nerves of the 
outer or under surface: flowers 3 to 5 in the axils of short chartaceous 
bracts; pedicels jointed near or below the middle, 16 mm, or less long 
in fruiting specimens; perianth white or greenish-white, 10 to 12 mm. 
long; segments 3-nerved, the inner slightly broader than the outer: 
stamens about equalling the perianth ; anthers coherent around the style ; 
filaments plicated: capsule oblong, obtusely triangular, 7 to 10 mm. in 
length, valves somewhat rugose or transversely ridged: seeds black, about 
1.5 mm. long and broad in the dried state. — Mexico. State of Jalisco: 
Rio Blanco, July, 1886, Dr. Edward Palmer, no. 185 (hb. Gr-). State 
of Oaxaca: Mountains of Jayacatlan, altitude 1540 m., 10 September, 
1894, L. CO. Smith, no. 188 (hb. Gr.). 
Very similar to this species is a specimen collected by Mr. C. G. 
Pringle on calcareous hills, Las Sedas, State of Oaxaca, altitude 1830 m., 
no. 5755 (hb. Gr.), but the anthers in Mr. Pringle’s specimens are 
quite distinct, hence according to the present interpretation of the 
genera Echeandia and Anthericum it must be referred to the latter 
genus, 
Echeandia macrocarpa. Scape 6 to 7 dm. high, leafy at the 
base, 2-3-bracteate above, glabrous: leaves lorate, 2 to 3 dm. long, 
1.2 to 2 em. broad, acute, entire or inconspicuously roughened along the 
margins, dark green and glabrous on both surfaces: inflorescence a 
glabrous panicle, about 3 dm. in length: pedicels jointed about one-third 
their length from the base, 2 em. or less long: flowers 3 to 5 in the axils 
of chartaceous bracts: perianth white (?), 8 to 12 mm. long ; segments 
8-nerved ; the outer 2 mm., the inner 3 mm. broad: stamens about equal- 
ling the perianth ; anthers united or coherent into a tube around the style:
