160 Robinson and Greenman—Menican Plants. 
lobes ovate-oblong, obtusish, 4 to 5 lines long, 23 lines broad at 
base: corona black.—Collected by C. G. Pringle, on hills above 
Oaxaca, altitude 6,000 feet, 6 August, 1894 (No. 4753). 
Buppiera FLoccosA Kunth. Two forms of this species are 
shown by Mr. Pringle’s 6025 (=6139) and by his 4925 from 
Oaxaca. The former numbers represent the typical form with 
rounded, deflexed interpetiolar appendages, while in the latter 
number these stipular structures are obsolete. No other differ- 
ences have been noted. The unappendaged form has also been 
secured in Guatemala by Donnell-Smith and von Tuerckheim. 
IpomM@A BRACTEATA Cav. var. PUBESCENS. A woody vine 
loosely twining to 15 feet: branches and petioles pubescent: 
leaves irregularly few-toothed, appressed sericeous-pubescent upon 
both surfaces.—UCollected by C. G. Pringle, on barrancas near 
Guadalajara, altitude 4,500 feet, 3 May and 9 July, 1894 (No. 
4734). 
“hae SUFFULTA Don. (Convolvulus suffulta HBK. Nov. Gen. 
et Spec. iii, 102, t. 211). So far as we can learn this species has 
never been collected since it was first found upon the volcano 
Jorullo by Humboldt and Bonpland. It has now been rediscoy- 
ered in Oaxaca, having been secured bv C. G. Pringle (No. 4755); 
on Monte Alban, altitude 5,800 feet by L. C. Smith (No. 141); and 
Valley of Oaxaca, altitude 6,500 to 7,800 feet, by E. W. Nelson 
(No. 154i). The root, apparently not seen by Kunth, is thick 
and woody: the stems many, slender, prostrate-ascending. 
J ACQUEMONTIA SMITHIIL. Suffruticose at base: much branched: 
stems procumbent: branches puberulent, ascending, 2 to 3 feet 
high, not twining: leaves ovate, acutish, mucronate, cordate, 
entire, puberulent upon both sides, the larger 15 to 2 inches long, 
two-thirds as broad; petioles 1 to 9 lines long: peduncles slender, 
1 to 24 inches long, loosely 2—5-flowered : pedicels 3 to 4 lines 
long: outer sepals rhombic-ovate, acuminate, about 3 lines long; the 
inner narrowly ovate, acuminate: corolla 6 lines long: lobes of 
the stigma thick, subglobose.—Collected by L. C. Smith, at 
Cuicatlan, Oaxaca, altitude 1,800 feet, 22 October, 1894 (No. 246); 
by C. G. Pringle, on dry calcareous soil, San Antonio, altitude 
2,500 feet, 1 September, 1894 (No, 4848); and by E. W. Nelson, 
six miles above Dominguillo, Oaxaca, altitude 6,500 feet, 22 Octo- 
ber, 1894 (No. 1600). Foliage and flowers much as in Z. violacea 
Choisy, but stem not twining, inflorescence looser, and lobes of 
stigma strikingly different, being in the latter species slender and 
almost linear. . 
SoLANUM PrineLet. Herbaceous, unarmed, with a soft gray 
pubescence; hairs simple, those of the stem and petioles spread- 
ing, of the leaves appressed : leaves single below, geminate above, 
ovate, acuminate, abruptly contracted to an acute base, 2 to 5 
inches long, two-thirds as broad; petioles 4 to 12 lines long: 
flowers an inch in diameter, blue, axillary in pairs; pedicels an 
inch or more in length: calyx urceolate with 5 or 10 small obtuse 
dark-colored prominences below the thin shallowly and bluntly
