NORTH AMERICAN EUPHORBIACE.E. 227 



Euphorbia polycarpa Benth. var yestita, Watson (Bot. 

 Calif., ii, p. 73). Beautiful specimens with comparatively 

 large rose appendages, deep maroon glands, and very char- 

 acteristic seeds. — El Rancho Viejo, April 20th. 



Euphorbia pediculifera Engelm var. minor, var. nov. 

 Procumbent, stems filiform; branchlets pubescent, espe- 

 cially near the involucreSj which are densely covered with 

 long white hairs. Leaves, ovate-obtuse very small, 1-3 

 mm. long by ll-^h i^ni. broad. Glands browaiish-green; 

 appendages white, transversely ovate, crenate; capsules and 

 seeds characteristic of the species. — Santa Margarita Island. 



Euphorbia conjuncta, sp. nov. Stems prostrate, spread- 

 ing, branches terete, dichotomous sparsely appressed hairy, 

 leaves oblong-sj)atulate, sparingly short hairy on the sur- 

 face, short petioled, unequal at the base, entire stipules 

 triangular hairy. Inflorescence solitary in the axils (before 

 the fruiting season they are so densely crowded with the 

 youDg leaves as to appear glomerate), involucres turbinate, 

 hairy, sessile or nearly so, lobes triangular, glands deep 

 maroon, transversely ovate; appendages from rose to white, 

 and of all forms (even on the same branch) from trans- 

 versely ovate entire, crenulate, or deeply blunt lobed, to 

 lanceolate, or in many cases entirely wanting; styles deeply 

 bifid, the lobes circinate. Capsule densely pubescent, 

 carpels carinulate, seeds ash color, oblong, obscurely tetran- 

 gular. with 3 strong transverse ridges that include the 

 angles. 



This peculiarly appendiculate species seems to form a 

 connection between U. pediculifera and U. glyptosperma. 

 Purisima, February 12th, only one developed fruit. 



Euphorbia involuta, sp. nov. Entire plant tomentose, 

 stems erect, irregularly branching, very fragile. Leaves 

 linear-spatulate obtuse, narrowing to the petiole, margin 

 entire^ strongly involute; petioles about one-third the length 

 of the blade, stipules deltoid. Inflorescence in compact
