80 ERYTHEA. 



ternate, nearly distinct; inflorescence of short, divaricate, leafless 

 terminal branches; involucres sessile in the forks, distinct to the 

 base, tomentose; segments 2 mm. long, oblong, acute; flowers very 

 numerous, tomentose without and within, campanulate at base and 

 separating very readily from the longer, tomentose pedicel; segments 

 nearly alike, obovate, greenish-gray; stamens 9; fruit not seen. 



Paraiso, Baja California, May 1, 1889, in the middle of the 

 peninsula, nearly opposite Cedros Island ; E. Orcidtianum of Proc. 

 Cal. Acad., ser. 2, vol. ii, 201, not of S. Wats. Collected by T. S. 

 Brandegee, and type in his herbarium. 



Whole plant yellowish-green, and so much resembling E. Orcut- 

 tianum that it was hastily passed over, in Mr. Brandegee's list, as 

 that species. The specimen is only a branch, but presumably taken 

 at the base. 



Eriogonum gossypinum Curran, has been again collected by 

 Miss Alice Eastwood, by Mr. J. Burtt Davy and others, in the 

 same general region. The original specimen was too old to clearly 

 show its relationship. The later ones leave no doubt^ that it is a 

 close ally of E. angulosum. Its akenes are not lenticular as 

 described, but globular below and only angular near the summit, 

 intermediate between the more angular ones of E. angulosum 

 and the short-globose ones of Nemacaulis denuclata. The flowers of 

 E. gossypinum are nearly those of the latter species. Nemacaulis 

 as a genus is entirely untenable. There are several other species of 

 Eriogonum with involucre divided quite to the base, and it is too 

 closely related to E. gossypinum to be geuerically separable from it. 



Chorizanthe insignis Curran, collected in the Santa Lucia 

 Mountains by Mr. W. Vortriede and by Miss Alice Eastwood, 

 shows as many as 9 flowers in the involucre. The seeds are not 

 lenticular, as described; but one angle is usually more prominent 

 than the other two, which causes a slightly flattened eflfect. If 

 there are any truly lenticular seeds in Eriogouere, I have not seen 

 them. What is usually meant by the term is, that the lower part of 

 the seed is globular, or sufficiently turgid to obscure the angles. 

 The upper part is always, so far as I have observed, triangular, 

 but often only at the very apex, as in Nemacaulis; in Eriogo- 

 num vagans, hirtifiorum, etc.; in Oxytheca dendroidea, and many 

 others.
