 and grassy fields near Spot Bay, Grand Cayman (1291, 1304); and an 

 ill-kept garden near San Miguel, Cozumel (1546). 



Euphorbia Brasiliensis Lam Encyc. 2:423. 



This species bears a very close habit resemblance to the preced-

Euphorbia Karwinskyi Boiss. Cent. Euph. 6. 



Dry, barren opens south of the lagoon at Progreso, Yucatan 

 (1696). In this species the involucre (according to the type speci- 

 men collected "Mexico and Huajaca, Karwinsky,") is hairy exterior- 

 ly, the involucral lobes are triangular-lanceolate, the glands minute, 

 the fifth being replaced by an obtriangular sulcus flanked by slightly 

 enlarged lobes, the appendages are minute crenated or wanting, and 

 the seeds pink or salmon-color, ovate-tetrangular .9 x .6 mm., the 

 ventral facets slightly 4-rugose transversely, the dorsal still more 

 slightly rugose, and the angle prominent. 



Euphorbia stipitata sp. nov. Plate lxvi. 



Annual, prostrate, stems and branches glabrous, internodes long, 

 stipules slender cylindro-aristate entire ; petioles short, leaves all 

 ovate-oblong, cordate and strongly oblique at the base; blunt at the 

 apex, pilose beneath, crenate-dentate except at the base. Inflores- 

 cence in terminal many-flowered short peduncled cymose clusters, 

 pedicels about the length of the peduncle and the involucre ; involu- 

 cres hairy, sub-campanulate or cylindro-campanulate, lobes triangu- 

 lar very hairy, glands 4, circular, raised on long stipes, appendages 

 small, rounded, white, attached to the stipe beneath and a little below 

 the gland, fifth gland represented by a broad, deep, round-based sul- 

 cus. Capsules pilose, carpids acute-angled, seeds pink-ashen 1.05 x 

 .65 mm., bluntly quadrangular, the dorsal facets plane, the ventral 

 slightly concave, all facets slightly marked by interlocking (not anas- 

 tomosing) ridges. 



Stems and branches glabrous except at their very tips 18-30 cm. 

 long, internodes 3.5-4 cm., nodal leaves 10-13 x 5~7 m m., involucres 

 1 mm. Related to E. maculata L. , from which it differs in its glab- 

 rous stems, immaculate supra-glabrous larger leaves, entire cylindro- 

 aristate stipules, and strong seed characters. Specimens from moist, 

 sandy pasture field near Guanica, Porto Rico (1782). Type in Field 

 Col. Mus. Herb. No. 61782.
