large clumps on the "sand wash " along the river. Although nearly 

 related to D. Parryi T. & G. and especially to D. divaricata Benth. 

 it seems to be specifically distinct. From D. divaricata it is easily 

 distinguished by its acuminate calyx teeth, its more numerous 

 glands, lai'ger leaves, and more robust erect habit. It is No. 129, 

 Proc. Cal. Acad., ser. 2, vol. iii, 126. Anthony's No. 352. 



Vernonia littoralis. Frutescent; stems brown, striate, slightly 

 pubescent, more so above; leaves ovate-acuminate, abrupt or cuneate 

 at base, denticulate with excurrent veinlets, slightly pubescent, 4-8 

 cm. long, 3-5 cm. wide on petioles 1-2 cm. long; inflorescence axil- 

 lary and terminal, the axillary corymbs as long as the leaves and 

 bearing a few small leaves ; heads 7 mm. high on pedicels of the 

 same length or shorter, 7-flowered; involucre broadly turbinate; 

 scales imbricated, the lower minute, the succeeding ones ovate- 

 acuminate, the upper linear, obtuse, all ciliate-pubescent, chartaceous, 

 with an evident mid-nerve; tube of the corolla slender, ampliate 

 above; pappus double, the outer copious, of very narrow palese 

 nearly the length of the 2^-mra.-long akene, the inner 4-5 times 

 longer; akenes broadly turbinate, smooth, obtusely 4-angled (with 

 several more or less indistinct intermediate ones. 



Collected on Socorro Island by A. W. Anthony not in sufficient 

 quantity for distribution. 



Eupatoriiim Purpusi. Herbaceous, 4-5 dm. high, glabrous 

 except a slight pubescence on the upper part of the stems; leaves 

 opposite, 3-uerved at base, membranaceous, ovate, sometimes cordate, 

 sometimes truncate at base, glabrous, crenate-serrate, acun)inate, the 

 largest 4-6 cm. wide, 9-12 cm. long, including the 3-6 cm. long 

 petiole; inflorescence corymbose, heads on pedicels 5-10 mm. long, 

 about 75-flowered, 8 mm. high and broad; bracts narrowly lan- 

 ceolate; scales of the involucre of equal length, linear-acuminate, 

 2—3 ribbed, equaling the corollas and pappus; corollas tubular, 

 ampliate above, purple or whitish, the lobes slightly pubescent; 

 akenes linear, 2 mm. long, sharply angled, smooth and glabrous, 

 contracted above and tipped with a thickened ring; bristles of the 

 pappus few and very slender, extremely deciduous. 



Collected by Dr. C. A, Purpus, at San Pablo, Baja California, 

 in 1898, and by the writer at the same place in 1889.
