March, igoo. Plants Utowanje Millspaugh. 63 



somewhat denticulate; leaves small, broadly ovate to orbicular, 

 entire, oblique cordate, retuse, mucronulate, somewhat sarcous. In- 

 florescence single in the upper axils of the branchlets; involucre 

 minute a mere expansion of the apex of the short thick pedicel; 

 lobes triangular, the apices prolonged beyond the glandular append- 

 ages, entire except the two flanking the rudimentary fifth gland, 

 which are 2-dentate on each side; glands minute, transversely oval, 

 plicate, raised on a short pedicel; appendages white, scant, three- 

 crenate; fifth gland represented by an aristate prolongation of the 

 involucral tissue as long as the true lobes. Capsule smooth shal- 

 lowly three-sulcate; carpids round angled; seeds pink, triangular 

 1 x .8 mm., the dorsal angle the most prominent, dorsal facets strongly 

 -convex, ventral concave, all smooth and devoid of markings. 



Stems 20-30 cm. long, branches 3-5 cm., internodes 1.5 cm., 

 nodal leaves 3x2.5-3 mm., involucres .5-. 75 mm. General habit that 

 of Pilea muscosa, related to E. serpens radicans and E. crassinodis 

 from which it differs in its thicker retuse leaves, involucral charac- 

 ters and larger seeds. Type from roadsides at Guanica, Porto Rico 

 (743), in Herb. Field Col. Mus. No. 60743. 



Euphorbia Andromedae sp. now Plate Ixv. 



Annual, prostrate, glabrous, with an almost inextricable mass of 

 short stems and 'branches proceeding from the crown of the root- 

 stalk, internodes short; stipules deltoid the free margin cut into 

 from 3-5 teeth; leaves oval to nearly orbicular, the base cordate and 

 unequal, the apex rounded, blunt serrate especially about the apex, 

 petioles about one-quarter the length of the leaf. Inflorescence 

 single in the axils of the upper leaves; involucres campanulate, pedi- 

 cel about one-third the length of the tube; lobes dentiform entire 

 except the two flanking the sulcus each of which have a lateral 

 tooth on the approximate margins; glands minute transverse-oval, 

 appendages oval entire, the two next the sulcus larger; fifth gland 

 represented by a tooth-like prolongation of the involucral tissue at 

 the base of the shallow sulcus. Capsule smooth, deeply tri-sulcate; 

 carpids sharply keeled; seeds reddish-brown .8x.6 mm., bluntly tri- 

 angular, all the facets convex and slightly roughened by minute 

 anastomosing ridges, ventral furrow deep. 



Near E. serpens H. B. K. The species differs from E. crassi- 

 nodis Urb. in its leaves, the length of the false gland, the entire 

 appendages, and particularly in the seeds. Stems and branches 

 4-8 cm. long; larger leaves 2.5-3 rnm. Found growing in the bot- 

 tom of shallow and deep pockets in the coral sea wall at Cape Cor- 

 ientes, Cuba, within the reach of the spray of the waves at high 

 tide (1466). Type in Herb. Field Col. Mus. No. 61466. 



Euphorbia articulata Aubl. PI. Guin. 1:480. 



E. linearis Retz. (E. articulata Anderss. Vet. Akad. Handl. 

 Stockh. 1853 (i855):236 from the Galapagos Islands is another spe- 

 cies: E. Anderssonii nom. nov.) Upper leaves ovate terminating 

 the branchlets, the others ovate-lanceolate to lanceolate-linear, all 

 apiculate and oblique at the base, the ovate small .8-1 x. 6 cm., 

 the ovate-lanceolate 1.6X.7 cm., the linear 4X.6 cm. Santurce,
