too much stress is laid by him on deviations from typical Lopezia, and 

 that the deviations are only specific and not generic. 



Linum gracilentum N, Sp. Very weak and slender annual, ascending 

 to erect from a decumbent base mostly. Branched below. Stems rounded, 

 but wiA a few vertical lines or striae. Intemodes 2-3 times as long as 

 the leaves. Leaves about 1 cm. long, thin and flat, acute, oval-ovate, in 

 fours, 1 -nerved. Whole plant smooth except the upper stems and pedicels, 

 which are hairy, margins of upper leaves, bracts and sepals cilate with 

 very short and gland-tipped hairs, but no evidence of glandular substance 

 exuded. Stems terminating in small and copiously flowered corymbs a 



and wide, with 



about 3 mm 



and 



^ong, and as long as the acummate-triangulai 

 calyx lobes, which are incurved over the depressed-globose capsules. Lobei 

 hyalme but with three green nerves. Flowers lemon-yellow, and about 4 

 «im. long. Stamens elongated. This plant belongs to the Grrggii group, 

 but seems to be undescribed. No. 22882, Tepic, Nayarit, February IS, 

 1927, growing in open slopes. 



Depdromecon Piercei N. Sp. Shrubby-based perennial, mostly 

 biennial, with ascending stems 2 feet high and tufted and little branched, 

 ending i^ few flowers on erect peduncles. Flower buds spherical and 

 about half an inch wide and like the rest of the plant glaucous. Sepals 

 2-3, round, imbricated, tardily deciduous, reflexed in anthesis and very 

 concave. Petals like those of Eschscholtzia Califomica but of uniform 

 lemon-yellow color throughout, about 1.5 inch wide. Stamens about 50, 

 and half as many as in Romneya and twice as many as in Eschscholtzia. 

 Ovary ending in a contraction or very short style which is terminated by 

 a peltate stigma which is concave above and inclined to be rectangular or 

 2-Iobed, and white, much as in Dendromecon rigidum but not so conspic- 

 uously 2-Iobed. Leaves those of Eschscholtzia Califomica but lobes very 

 narrowly linear. Fruit a 10-striate linear capsule like Dendromecon. 

 1 his plant Mr. Pierce informs mc was got originally in a package of 

 seeds sent him as Eschschdtzia Mexicana. It has been growing in his 

 garden for over five years and resceds itself regularly, and breeds true. 

 It therefore cannot be a hybrid. The leaves are wholly unlike Dendro- 

 mecon, and the habit is that of an Eschscholitzia, but the stigma and 

 sepals are very different The sepals of EsehsdMltzia are calyptrate, Aat 

 IS united at tip and pulling off as the flower opens. The stigmas are 

 Imear-subulate and m the larger flowers a cm. long, and erect. The 

 stigma of Dendromecon is flat and 2-ldbed and rather sUpitate. The 

 stigma of RtHtiQeya is that of Argemone and Papaver that is radiate, ses- ' 

 sile and of 10 parts flat oo the tip of the capsafe. 



Toumefortia Tepicana N. Sp. Shrub 6-10 feet high, with slender 

 branches «id copious leaves. Stems spreading-strigose. Leaves about 1 

 dm. long by 4 cm. wide, elliptical, shortly acuminate, rounded to trun- 

 cate at base, entire, ashy with appressed white hairs which are brownish 

 and more prominent on the nfirwss. Petiflles, steat aa^ i cm. long Inflor-
