cordate or subcordate, 3 to <) inches broad, punctate above and with a 

 soft deciduous tomentum beneath, the lobes lanceolate, rounded at the 

 apex and inconspicuously niucronate, or in young leaves sometimes 

 acutii?h, the two outer lobes of the larger leaves each appendaged at 

 base with a large blunt auricle ; petioles an inch long or more, rough- 

 ened especially near the base by numerous small tuberculate glands : 

 peduncles 2 inches long, l-flowered, puberulent ; bractlets minute or 

 obsolete ; pedicels half an inch long: sepals ovate, with rounded apex, 

 4 lines long, canescent with very short ai)pressed silvery hairs ; co- 

 rolla nearly 3 inches long, twice the length of the stamens, purple. — 

 Calcareous ledges near Monterey ; June, 1889 (n. 2840). Allied to 

 Ji digitata, L., but differing in its l-flowered peduncles and glandular 

 petioles, as well as in the shape and pubescence of the leaves. The 

 flowers are also larger and the throat relatively narrower. 



Bassovia Mexicana. A shrub, 5 to 15 feet high; branches un- 

 equally dichotomous, slightly striate-angled and minutely verrucose : 

 leaves membranaceous, geminate, ovate, acuminate, the larger 1^ to 2 

 inches long, | to 1 inch broad, the smaller half as large, all abrupt at 

 base or slightly decurrent on one side upon the slender petiole, green 

 on both sides, slightly scabrous above, sparsely pubescent on the veins 

 beneath : inflorescence umbelliform, sessile, axillary ; pedicels 2 to 6, 

 l-flowered, 4 to 5 lines long, striate, slightly thickened upward : calyx 

 spreading, shallow cup-shaped, strictly truncate, persistent; corolla 3 

 to 3^ lines in length, divided to the middle or even more deeply ; tube 

 short, slender; limb campanulate, of 4 or 5 lanceolate acuminate seg- 

 ments, puberulent upon the outside; stamens exserted, the filaments 

 at maturity exceeding the anthers ; throat of the corolla and base of 

 the filaments bearded : fruit the size of a pea, red (turning black?), 

 many-seeded ; seeds a little over half a line in diameter, compressed, 

 roughened with pits. — Tamasopo Cafion, San Luis Potosi ; June, 

 1890 (n. 3071). Resembles some species of the genus Brachistus 

 in its truncate calyx, but has the deeply cleft valvate corolla of Bas- 

 sovia, and shows close affinity to B. macroplnjlla, Benth. & Hook. 

 (Witheringia macropl/ylla, auct.), from which it differs principally in 

 its ligneous stem, much smaller leaves, fewer-flowered fascicles, and 

 more persistent calyx. The distinctions between Bassovia and Bra- 

 chisfus are not at all satisfactory, and considering the intermediate char- 

 acter of this new species it seems best to refer it to the older genus. 



AVithania(?) melanocystis. a shrub, 5 to 8 feet high, minutely 

 pubescent on the leaves and younger parts; branches gray, striate : 

 leaves single or geminate, lanceolate to ovate-lanceolate, acute, entire
