Lithospermum Nelsonii, n. sp. An havinbeoas perennial : stems 
erect from a ligneous base, 2.5 to 4.5 dm. high, sparingly branched 
above, pubescent with spreading hirsute hairs intermixed with a sub- 
appressed puberulence: lower stem-leaves oblanceolate, 3 to 7 cm. long, 
8 to 18 mm. broad, obtuse or submucronate-acute, narrowed below into a 
winged sub-petiolate base, hirsute-hispid on both surfaces, more or less 
3-nerved ; upper stem-leaves sessile, oblong-lanceolate : flowers on short 
pedicels, disposed in the axils of the uppermost leaves forming a leafy- 
bracteate scorpioid raceme: calyx deeply 5-parted ; divisions linear, about 
one half as long as the tube of the corolla, acute, hirsute-pubescent : 
corolla salverform, white or pale yellow; tube 13 to 14 mm. long, ex-

CaPRARIA MEXICANA, Moric. in DC. Prodr. x. 429. Specimens 
collected by Mr. E. W. Nelson at Soto Ja Mariana, State of Tamaulipas, 
no. 6643 (hb. Gr., and U. S. Nat. Mus.), agree in all details with 
the original description of the above species. Although C. mexicana 
has been considered by some authors to be identical with the widely 
distributed species C’. biflora, L., yet on account of its glabrous character 
throughout, the uniformly narrow-lanceolate acuminate leaves, the long 
anthers, and the more acute corolla-lobes, it seems to the writer well 
worthy of specific rank. In addition to Mr. Nelson’s no. 6643, the fol- 
lowing specimens may be referred to C. mexicana, Moric: en route from 
= Luis Potosi to Tampico, December, 1878, to February, 1879, Dr.
