. . . . obscurely glandular toothed;" while those of our 

 specimens are oblong lanceolate, acute to cuneate at the 

 base, the margin regularly serrate, the teeth armed with 

 an incurved bristle. Leaves 1^-5 cm. long, and J-IJ cm. 

 wide. 



This plant, is so far provisionally placed under Sehastiania, 

 the peculiar bi-locular ovary and two thick, twisted styles, 

 as well as the imperfect columella and estrophiolate seed, 

 will probably cause its removal from this genus when it 

 is better known. — Purisima, February 12th, in excellent 

 floral condition, but lacking fruit. 



PeDILANTHUS (§ EUPEDILANTHUS) MACEOCAKPUS Eentll. 



(Bot. Sulph. Voy., p. 49.) Magdalena Island, January 12th, 

 with old fruit. — El Llano de Santana, May 10th, in flower. 



Euphorbia (§ Anisophyllum.) 



Euphorbia pycanthema Engelra. (Bot. Mex. Bound. Surv. 

 2, p. 188.) Forma serrata, the lower leaves sharply serrate 

 upon one or both margins. — Pozo de Los Dolores, April 5th. 

 Too young for good fruit. 



Euphorbia hypericifolia Linn. (Hort. Cliff. ,198.) The 

 specimens are of the true West Indian form, from which 

 the species was made. — Purisima, February 14th. 



Euphorbia serpens Kunth. (in H. B. nov. gen. et sp. ii, 

 p. 41). Our specimens are of a form hairy at the nodes and 

 upon the younger branchlets. — Magdalena Island, January 

 23d. 



Euphorbia Magdalene Benth. (Bot. Sulph. Voy., p. 50). 

 Our specimens agree precisely with Bentham's description, 

 which, however, is incomplete as to flowers and fruit. Dr. 

 E. Palmer's specimen (No. 26 of his collection at Muleje, 

 Lower California) lacked fruit. We therefore add the fol- 

 lowing to Boissier's description of the specimen in hei-b. 

 Bentham (D. C. Prod., pars, xv, p. 37), and that of Watson 

 from Dr. Palmer's specimen (Proc. Am. Acad., xxiv, p.
