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. 

 3392. Types in herb. Gray and herb. U. S. Nat. Museum. 



Polygonum Meisnerianum, 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. Meisneri- 

 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 Ceutrali-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 

 soriceous-tomentose beneath, 4 to 6 or more cm. long, about half as 

 broad ; pubescent petioles about 1 cm. long : heads oval, obtuse, leaf- 

 less, 1.4 to 2.2 cm. long, 1.4 cm. in diameter, borne in 2-4-chotomous 

 spreading round-topped panicles ; ultimate tomentose pedicels 1 to 1.5 

 cm. 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 canftn above Totolapam by C. & E. 

 Seler, 3 January, 1896, no. 1637. Near T. pubijiora, Moq. and (ex 

 char.) T. pycnantha, Moq. Differing from the former in its rounded 

 many-headed panicles and from both in its larger strongly villous flowers. 

 Type in herb. Gray. 



Mimosa Deam.ii. 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 to 

 2.7 cm. long : pinnae a single pair ; their rhachises about 5 cm. long, 

 each bearing 5 to 6 pairs of leaflets, strigose ; leaflets elliptical, rounded 

 at each end, coriaceous, glabrous above, sparingly strigose (chiefly on 

 the excentric midnerve) beneath, 2.3 to 3.6 cm. long, half as broad, 3-4-
