petiole ; segments 15-19, broadly oblong, acutish, generally 1-2-toothed 

 upon the lower margin, 5-7 lines long, 2.V-4 lines broad; the upper 

 ones approximate ; the lower becoming smaller and more or less 

 scattered : inflorescence exceeded by the leaves, loose below, the lowest 

 jjedicels being 1^ inches long: calyx lobes oblong-lanceolate, acute, 

 slightly unequal, 2-3i lines long : corolla pure white, i inch in 

 diameter; lobes rounded, cleft half-way to the base ; appendages linear, 

 folds free at the tip and forming pairs alternating with the stamens : 

 filaments equalling the corolla, hirsute below : style 2-parted for two 

 thirds of its length and easily divided to the base ; ovary hirsute ; 

 ovules about 20. — Collected on cliffs in a pine forest of Strawberry 

 Valley, Chihuahua, by Mr. Hartman, 8 June, 1891 (no. 686). A 

 species of the § Eutoca. 



Ltcium retdsum. Stems glabrous, smooth, dark brown or grayish, 

 sometimes armed with short slender spines ; branchlets divaricate . 

 pulvini white, pubescent ; leaves obovate, cuneate, usually retuse, 

 pubescent upon both surfaces : pedicels filiform, glandular-pubescent, 

 3-5 lines long : calyx tubular, glandular-pubescent, ''Ih lines long ; teeth 

 triangular-lanceolate, erect, acute, a third as long as the tube : corolla 

 trumpet-shaped, about 4 lines in length; teeth short, retuse, a fourth 

 as long as the tube : style and stamens exserted ; the latter unequal ; 

 filaments bearded at the base : fruit not seen. — Collected at Opata, 

 Sonora, at 3,450 feet, by Mr. Hartman, 1 November, 1890 (no. 212). 



Maurandia (?) GENicuLATA. Densely glandular pubescent and 

 viscid : stems zigzag : leaves distichous, orbicular, cordate, coarsely 

 crenate, 1-2 inches broad, green upon both sides, 5-nerved ; petioles 

 spreading, 5-9 lines long : peduncles axillary, \-\ inch in length, 

 ascending in anthesis, somewhat thickened and recurved in fruit : calyx 

 narrowly campanulate, subequally 5-cleft to near the middle, 6 lines 

 long; segments narrowly ovate, obtusish, 1-nerved, somewhat plaited 

 at the sinuses: style simple, filiform, nearly or quite an inch in length ; 

 ovary superior, 2-celled ; ovules numerous, upon axial placentEe : fruit 

 capsular, about equalling the calyx ; seeds oblong, barely a line in 

 length, two thirds as thick, black, irregularly roughened with relatively 

 large tubercles but not at all winged : corolla and stamens not seen. — 

 Collected on cliffs at Nacory, Sonora, at 3,750 feet, by Mr. Hartman, 

 1 December, 1890 (no. 272). Closely resembling in foliage and 

 pubescence M. erecta, Hemsl., but with a very geniculate stem and 

 wingless seeds. Until the corolla and stamens are discovered the 

 generic position must remain somewhat doubtful.
