Perezia hebeclada, Gray (PI. Wright. I. 127). This rare spe- 

 cies has been rediscovered by Mr. Pringle, and his excellent specimens 

 show the following additional characters. Leaves coriaceous, crowded, 

 strongly reticulate, oblong, sagittate-cordate, abruptly pointed, 4 inches 

 or more in length, nearly half as wide ; the upper gradually diinin- 

 ishing in size, acuminate. — Pedrigal, Valley of Mexico, Federal Dis- 

 trict, December, 1892 (n. 4360). 



Perezia yernonioides, Gray (Proc. Am. Acad., XXII. 433), 

 founded upon Palmer's no. 745 from Jalisco, proves to be a form of 

 Vernonia serratuloides, HBK. 



Lobelia picta. Glabrous, 6-8 inches in height: stems slender, 

 decumbent, rooting from the lower joints, simple or with one or two 

 branches from near the base, leafy, minutely angulate through the de- 

 current margins of the leaves : leaves linear, sessile, narrowed to an 

 obtusish point, inconspicuously appressed-serrulate, 1 -veined, thickish, 

 1 inch in length, | line in width ; a few of the lowest leaves of a very 

 different form, broadly spatulate, obtuse, 3-4 lines long, narrowed 

 to a very slender petiole 6-8 lines in length : inflorescence spicate- 

 racemose^ raised on a naked peduncle an inch or more in length : bracts 

 linear, 1-2 lines long, the lower equalling, the upper exceeding the 

 pedicels : flowers nodding, i inch in length : calyx tube symmetri- 

 cal, becoming in fruit almost hemispherical, exceeded by the linear 

 acute serrulate teeth : corolla tube not equalling the calyx teeth, lobes 

 lanceolate or ovate-lanceolate, acute, 3 lines in length, light blue or 

 white, conspicuously pencilled with dark blue : filaments short, pubes- 

 cent : anthers hispidulous, the two lower slightly smaller, tufted at 

 the apex, the other three with minute setas. — Cold springy meadows, 

 Sierra de las Cruces, October, 1892 (n. 4305). A very attractive 

 species with small but beautifully variegated flowers ; to be distin- 

 guished from L. OrizahfE, Mart. & Gal., and L. paucijlora, HBK., 

 by its very short corolla tube, by the hispidulous anthers, etc. ; from 

 L. Irosuensis, Plan. & Oerst., by the symmetrical calyx not acute at 

 the base. 



Arctostaphylos rupestris. a shrub 4-10 feet high with 

 brown shreddy bark : leaves 4-5 inches long, coriaceous, oblong-ellip- 

 tic, acute at both ends, finely serrate with cartilaginous teeth, when 

 young erect, pubescent above, densely ferruginous-tomentose on the 

 under surface, with age reflexed, glabrate above, and becoming less 

 tomentose and tawny beneath, not however glabrate : racemes of the 

 panicle rather loosely flowered, scarcely at all secund, covered with a 

 fine gra'yish pubescence ; bracts crimson, lanceolate, 3 lines long,
