264 PORTULACACEiE. Purtulaca. 



orauge and partly red : stamens 7 to 27 : style-lobes 3 to 6 : capsule turbinate, winged with 

 a circular rim left by circumscissiou of the calyx above the aduate portion ; seeds rough- 

 tuberculate, cinereous. — Granitic region of W. Texas,^ Lindheimer, &c., to New Mexico and 

 Arizona,- Wright, Greene, liuthrock. "Said not to be eaten by swine," Reve7-chon. (The 

 Cuban plant, coll. Wright, referred to this on account of the capsule, has bearded axils, and 

 is distinct, being probably P. oleracea, var. minor, Griseb.) 



* * Leaves terete or nearly so, subulate-lanceolate to linear, hairy in their axils, otherwise 

 glabrous : calyx-lobes not carinate. 



P. stelliformis, Mocino & Sesse. Perennial by creeping tuberous-thickened and some- 

 times moniliform rootstocks : stems erect or ascending, a span to a foot high : leaves quite 

 terete, slender, mostly inch long, those involucrating the flowers in a radiating cluster much 

 surpassing them : axillary clusters of hairs short and soft : petals copper- or buff-colored, 

 obcordate or emargiuate, ((uarter inch or more long : seeds blackish, grauulate-tuberculate, 

 with metallic lustre. — Moc. & Sesse' ace. to DC. Prodr. iii. 353, under P.Jhliom, and repre- 

 sented in Caiques des Dess. t. 389. " P. foliosa, Lindl. Mexicana," A. DC. Caiques des

 {vai. erecta) ; Wats. Proc. Am. Acad. xxi. 417, with doubt, the tuberous roots indicated. 

 P. suffrutescens, Engelm. Bot. Gaz. vi. 236, but is not suffrutescent. — Plains of W. Texas to 

 Arizona, Wright, &c. (Mex., Lower Calif.) 



P. halimoid.es, L. Mostly perennial, fleshy-rooted, erect or diffuse, corymbosely branched : 

 leaves short, moderately flattened, half inch or less long, uppermost well involucrating the 

 flower-clusters ; hair copious : petals yellow : capsule-lid depressed, much shorter than the 

 basal portion ; seeds granulose, reddish, at least when young. — Spec. ed. 2, i. 639 (Sloane, 

 Jam. t. 129, f. 3); DC. Prodr. iii. 354; Griseb. Fl. W. Ind. 57. — Keys of Florida, Blodgett, 

 Garber, Curtiss. (W. Ind.) 



P. pilosa, L. Annual, sometimes indurating in age,** ascending or spreading : leaves nearly 

 terete, linear-subulate, half or quarter inch long, either much or little surpassing the copious 

 axillary hair : petals from carmine to crimson or purple, a line or two long, retuse : capsule- 

 lid hemispherical ; seeds blackish and with metallic lustre, muriculate-granulose. — Spec. i. 

 445 (Comm. Hort. t. 5 ; Pluk. Aim. t. 247, f. 7, &c.) ; Bot. Reg. t. 792 ; Griseb. 1. c. — Sandy 

 open ground, Florida and Texas to Arizona,* and a few places in California, where probably 

 introduced. (All Trop. Am., &c.) 



P. parvula, Gray. Annual, or becoming fleshy-rooted, depressed and diffuse: leaves 

 nearly terete, oblong-linear, obtuse, 2 to 5 lines long, with copiously hairy axils : petals 

 yellow and copper-colored, barely a line long : lid high-hemispherical, fully as long as basal 

 part of capsule ; seeds pale red, minutely granulate. — Proc. Am. Acad. xxii. 274. P. pilosa.

 &c. — Plains of W. Texas and New Mexico, Fendler, Wright. (Mex.,^ Schaffner, 772, 

 Pringle, 543, &c.) 



P. GRANDiFLORA, Hook., of Extra-tropical S. America, related to P. pilosa, is the showy 

 Portulaca of ornamental cultivation. It tends to become spontaneous in the S. Atlantic States. 



2. TALIN6PSIS, Gray. (Likeness to Talmum, which is not close.) — 

 PI. Wright, i. 14, t. 3 ; Benth. & Hook. Gen. i. 157, where " sepala 3 " is a 

 misprint. — Single species. 



1 P. coronata, Small (Bull. Torr. Club, xxiii. 126), from Stone Mt., Georfjia, if distinct, is a very 

 closely related species. Although Dr. Small has kindly furnished excellent alcoholic material of the 

 Georgia plant, it has been impossible as yet to find satisfactory distinctions between it and the Texan 

 species. Perhaps these may appear when better material of the latter can be obtained. 



2 Also Lower Calif., Brnndegee. 



3 Specimens with distinctly perennial roots have been collected at Eustis, Fla., Nash, which, while 

 resembling P. halimoidesin habit, have the capsule of P. pilosa.
