GREENMAN. — MEXICAN PHANEROGAMS. 569 



ate at the base, entire, glabrous and smooth upon either surface, or 

 slightly roughened on the prominent midrib and nerves beneath, rather 

 strongly reticulately veined, the lower surface somewhat glaucous : in- 

 florescence racemose ; racemes axillary, including the peduncle 6 cm. or 

 less in length ; rhachis, pedicels, and the minute bracts closely ferrugine- 

 ous-stellate : flowers subsecund : calyx cupulate, 5 to 6 mm. high, about 

 equalling the pedicels, shallowly sinuate, 5-dentate, argenteous-lepidote : 

 corolla about 1.5 cm. long ; externally and along the margins of the 

 upper surfaces of the lobes argenteous-pubescent or somewhat scaly : 

 filaments and ovary above stellate-pubescent: fruit not seen. — Collected 

 by C. G. Pringle in mountain canons above Cuernavaca, State of Morelos, 

 altitude 2,000 m., 15 May, 1898, no. 6848. 



The species is named in honor of Sr. Dr. Jose Ramirez, Director of 

 El Institute Medico Nacional, City of Mexico. 



Menodora helianthemoides, Humb. & Boupl., var. parviflora. 

 Stems several, procumbent, more or less branched, 5 to 20 cm. long: 

 foliage and inflorescence of the species : calyx 6 to 7 mm. long, usually 

 11-lobed: corolla about 1cm. long, equally 5-lobed ; lobes oblong- 

 elliptic, 6 to 7 mm. long, 3 to 4 mm. broad : mature capsule about 6 mm. 

 high, nearly 1 cm. broad. — Collected by C. G. Pringle on bare hills 

 above Pachuca, State of Hidalgo, altitude 2,600 m., 30 July, 1898, 

 no. 6918. 



A well marked variety, differing from the species chiefly by the smaller 

 flowers and less hirsute-pubescent branches. 



Sabbatia arenicola. Annual, glabrous throughout: stems 5 to 10 

 cm. high, dichotomously much-branched, more or less 4-angled : leaves 

 sessile, ovate-oblong to elliptic-oblong, 0.5 to 1.5 cm. long, about one 

 half as broad, obtuse, entire, thickish. inconspicuously 3-5-nerved : flowers 

 terminating the branches, pedunculate : peduncles 0.5 to 1.5 cm. in 

 length : calyx campanulate, pentagonal, later becoming turbinate and 

 strongly 5-ribbed along the angles ; lobes lance-oblong, 5 to 10 mm. 

 long, 2 to 4 mm. broad, obtuse, entire : corolla lilac or rose-purple, about 

 1 cm. or more in diameter, yellowish in the throat, persistent ; lobes 

 obovate-rotund : stamens adnate to the throat of the corolla ; filaments 

 one half as long as the corolla-lobes : mature capsule 5 to 6 mm. long ; 

 seeds strongly reticulated. — Collected by C. G. Pringle on damp sands 

 of seacoast near Tampico, State of Tamaulipas, 28 April, 1898, no. 

 6808. 



A species most nearly related to S. camjyestris^ Nutt., but readily 

 distinguished by the less attenuate calyx-lobes and the much smaller 

 corolla.
