and branches sparingly covered with very short straight conical spines 
(0.5 mm, in length): otherwise corresponding closely to the typical West 
Indian plant. — Collected by E. W. Nelson between Tumbala and El 
Salto, Chiapas, Mexico, altitude 466 to 1,400 m., 29 October, 1895, no.

Potyeonum MeEIsNer1aNnumM, Cham. & Schlecht., var. jalapense. 
Stems, ochreae, leaf-margins, and bracts covered with numerous stalked 
glands; prickles (developed in the typical form) obsolete: leaves inclin- 
ing to hastate lobing at the base. — This is probably the P. Meisnert- 
anum of Cham. & Schlecht. in Linnaea, v. 90, but much more glandular 
than the typical form, characterized in Linnaea, iii. 40. — Collected by 
C. G, Pringle in wet places near Jalapa, Mexico, altitude 1,225 m., 5 
April, 1899, no. 8111. This species appears to have been overlooked by 
Mr. Hemsley, as it is not recorded in the Biologia Centrali- Americana. 
Telanthera mollis. Branches lignescent, terete becoming sub- 
quadrangular near the slightly tumid nodes, covered when young with a 
soft short spreading or even reflexed pubescence, at length quite 
glabrate: leaves lance-oblong, entire, acute at each end, finely appressed- 
pubescent and (in the dried state) rugulose above, much paler and 
sericeous-tomentose beneath, 4 to 6 or more em. long, about half as 
spreading round-topped panicles; ultimate tomentose pedicels 1 to 1.4 
em. long; bracts ovate, acute: sepals oblong, acute and pungent, sub- 
equal, 7 mm. long, dorsally covered with long dense silky hair: stamineal 
tube a little shorter than the ovary, the sterile segments 2.3 mm. long; 
fimbriated above, about equalling the filaments and somewhat surpassed 
by the anthers: style nearly as long as the ovary; stigma globose, — 
unlobed. — Collected in Oaxaca in a cafion above Totolapam by C. & E- 
Seler, 3 January, 1896, no: 1637. Near 7. pubiflora, Mog. and (eX — 
char.) 7. pycnantha, Moq. Differing from the former in its rounded — 
many-headed panicles and from both in its larger strongly villous flowers. |

Mimosa Deamii. Arborescent, 3 m. high: branches terete, unarmed, — 
fuscous, tomentulose and roughened by the enlarged persistent bases of 
strigose hairs; stipules short, thickish, subulate, strigose: petioles 1.5 t0 
2.7 em. long: pinnae a single pair; their rhachises about 5 cm. long, 4 
each bearing 5 to 6 pairs of leaflets, strigose; leaflets elliptical, rounded : 
at each end, coriaceous, glabrous above, sparingly strigose (chiefly 0? 
_ the excentric midnerve) beneath, 2.3 to 3.6 em. long, half as broad, 3-4 |
