﻿PLANTS FENDLERIANiE. 57 



often 2-3-cleft divisions. The marginal flowers are pistillate only, and fertile; the 

 central are staminate. My specimen exhibits scarcely full-grown fruit, with one of the 

 mericarps 4-winged, the other quite uniformly 3-winged (but Nuttall's specimen shows 

 some 10- winged fruits), and the wings are broad and membranaceous, often unequal. 

 Frequently the mericarps appear to be more or less dislocated, and one is often imperfect. 

 Although the commissure is nearly plane, the albumen shows a manifest tendency to be- 

 come involute ; and in a specimen gathered by Fremont in his second expedition (in 

 herb. Ton.), with perfectly mature fruit, the section of the albumen is strictly semilunar, 

 as is also the case in a smaller degree in C. campestris and even in C. glomeratus. The 

 genus might, therefore, as well be referred to the Campylospermse, if there were a tribe to 

 receive it : but as the wings belong to the primary juga, it cannot be placed in the Else- 

 oselinese. — In Fremont's specimen the carpophore is seen to be free and 2-parted, just 

 as in C. campestris ; and the fleshy root is fully six inches long and much thickened 

 downwards. 



y 276. Thaspium ? montanum. (sp. nov.) : glaberrimum ; caule erecto gracili e radice 

 fusiformi crassa ; foliis biternatisectis, foliolis cuneiformibus trifidis, lobis oblongis lanceo- 

 latisve nunc linearibus integris vel majoribus incisis ; petiolis longe spathaceo-dilatatis ; 

 involucro nullo ; involucello e foliolis circ. 9 setaceis insequalibus pedicellos ajquantibus. 



— Sunny declivities, at the foot of mountains, along Santa Fe Creek ; April and July. 



— There are two forms in the collection ; one, probably the vernal state, is only a span 

 high, with the leaves cut into linear or lanceolate divisions ; the other, probably gathered 

 in July, is a foot or two in height and with coarser foliage. There is apparently no 

 other distinction. The base of the stem is clothed with brown vestiges of radical 

 sheaths. The flowers are bright yellow. One specimen exhibits half-grown fruit, which 

 agrees very well with Thaspium, except that the dorsal wings are rudimentary : the in- 

 tervals show single or double vittae.

 the collections made in Northern Mexico.
