156 Planta Lindheimeriane. 
margins of the latter aculeolate-ciliate, or in Lindheimer’s 
specimens nearly smooth and naked. It is probably only an 
annual, as likewise the next. Mixed with this, in the distri- 
bution, and probably forming the whole in many sets, are 
fruiting specimens with the upper leaves sparser and the tips 
of the branches naked, like a short peduncle. These belong 
to the following species, if indeed it be different, and to the 
New Braunfels locality there cited. 
339. L. uupsonioipes, Planchon J. c. p. 186. New 
Braunfels, growing in dense patches, on dry soil, with a rocky 
substratum, in naked places in the prairies; May; in fruit; 
(distributed under No. 338). In clayey soil, Agua Dulce on 
the Matagorda Bay; February, in flower.— The leaves are 
less approximated and less squamous than in the preceding ; 
the uppermost sparse on the branches, so that the flower, and 
especially the fruit, is raised on a manifest peduncle, some- 
times of more than half an inch in length. The capsules and 
the flowers are larger; the yellow petals nearly five lines in 
length. But it too closely resembles L. multicaule, of which 
it is perhaps only a variety.

the flowers, and the laxer leaves, this species is hard to dis- 
tinguish from L. rigidum. Both, I believe, are annuals ; but, 
as they flower through a great part of the year, the root hard- 
ens, and the base often shows the vestiges of earlier stems, 
which have perished ; thus giving it somewhat the appearance 
of a perennial. The styles are united either for two-thirds 
of their length, or almost to the apex. One of Lindheimer’s 
specimens in my set (gathered in 1846) not indistinctly 
shows small stipular glands; while that of the Coll. 1847-8 
does not. ‘These glands are equally visible in some of the
