This species has been hitherto confused with N. origanifolhim, HBK., 

 and N. rupicola, Bonpl., which are both species with distinctly suffruti- 

 cose stems, while N parvifolium is an annual. From the former, 

 namely, N origanifolhim, the species here proposed is readily distin- 

 guished by the broader leaves and larger flowers ; and from the latter, 

 namely, N. rupicola, by the cinereous-hirsute character of the leaves, not 

 densely white-tomentose on the under surface, and by the larger flowers, 

 lance-linear not spatulate calyx-divisions. 



Cordia stellata. Shrub, much-branched ; branchlets, as well as the 

 foliage and inflorescence, densly covered with a canous-stellate tomen- 

 tum : leaves petiolate, ovate, 2.5 to 10 cm. long, 1.5 to 8 cm. broad, 

 obtuse, irregularly crenate-dentate, cuneate or subcordate at base, and 

 the lamina usually short-decurrent on the petiole, densely canous-stellate- 

 pubescent on both surfaces, paler and rather conspicuously reticule-nerved 

 beneath; petioles 4 to 12 mm. long, channelled above, densely stellate- 

 pubescent ; inflorescence terminating the stem and branches in peduncu- 

 late spherical heads, 1.5 to 2 cm. in diameter; peduncles 2 to 4 cm. 

 long : calyx obovoid, 5 to 6 mm. long, somewhat inflated, shortly and 

 obtusely 5-dentate : corolla white, more or less salver-shaped, or sub- 

 campanulate ; tube slightly exceeding the calyx ; limb about 1 cm. 

 in diameter, 5-lobed, strongly reticulate-veined. — Mexico. State of 

 Oaxaca : altitude 615 m., 27 August, 1894, L. C Smith, no. 147 

 (hb. Gr.) ; Cuicatlan, altitude 600 m., 16 September, 1899, V. Gonzalez 

 no. 983 (hb. Gr.) ; about 9.5 kilometers above Dominguillo, altitude 

 640 m., October, 1894, E. W. Nelson, no. 1646 (hb. Gr., and hb. U. S. 

 Nat. Mus.). 



In general aspect Cordia stellata resembles C. Pringlei, Bobinson, 

 with which species it has been hitherto confused. The entire plant,
