Mr. John Donnell Smith submitted to me a bundle of Sola- 
naceous plants from his recent Gautemalan collections. Among 
them I find the following species which seem worthy of char- 
acterization, althouglr in the present confused state of our 
knowledge concerning this perplexing group absolute certain- 
ty seems unattainable. Without any desire of. possibly mul- 
tiplying synonymy these species are put on record as follows: 
Solanum Donnell-Smithii n. sp. — Said to be a vine, more 
or less rough with stellate hairs: prickles stout and subulate | 
or recurved, yellowish, especially stout on the stem, usually 
more slender on the midrib and principal veins, copious or 
scanty: leaves rather large and membranaceous, oblong or 
ovate, sinuate-toothed or lobed, or even entire; 7 to I5 cm. 
long, with equally 4. to 6-rayed hairs below, and central 
division much elongated in the otherwise shorter-rayed hairs 
above: the simple loose few-flowered racemes or cymes soon 
lateral: calyx deeply 5-cleft, with stout often bulbous-dilated 
prickles and mostly long-acuminate lobes: corolla 9.5: cm. or 
more in diameter, whitish or light blue(?), deeply parted into 
lance-linear lobes, which are thickly stellate-pubescent with- 
out: anthers linear-lanceolate: the smooth globose berries be- 
coming 1.5 to 2 cm. or more in diameter, turning red(?).— 
Escuintla, Depart. Escuintla, alt. 1100 ft., March 1890 (4x 
5. 2268); Concepcion, Depart. Escuintla, alt. 1200 ft., April 
1890 (7. D. S. 2261); San Juan Mixtan, Depart. Escuintla, 
alt. 500 ft., April 1890 (5. D. S. 9962). 
Brachistus Eseuintlensis n. sp. — Glabrous throughout or 
minutely puberulent: leaves large and thin, ovate (often 
broadly so), acute or acuminate, usually oblique at base and 
, more or less tapering into a petiole, entire or with a slightly 
wavy margin, very unequal in size, the largest becoming 920 
to 23 cm. long and 12 to 13 cm. broad: flowers on pedicels of 
various lengths in umbellate axillary clusters along the main 
stem or on leafy branches: the short and broadly campanulate 
calyx with an entire margin (rarely a few almost indistin- 
guishable teeth): corolla about 12 mm. long with 5 erect 
lobes 4 or 5 mm. long: berry globose, 8 to 9 mm. in diam- 
eter.— Escuintla, Depart. Escuintla, alt. 1100 ít, March 
1590 C* .D..S. 9901). Eu
