PLANTH FENDLERIANE. 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 F remont in his second expedition (in 
herb. Torr.), 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 Campylosperme, if there were a tribe to 
receive it: but as the wings belong to the primary juga, it cannot be placed in the Ele- 
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.

— Sunny declivities, at the foot of mountains, along Santa Fé 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 vitte. ;
