Lagophtlla. COMPOSITiE. 403 



Plains near Wallawallah, Oregon, Nuttall! — A remarkable plant, 2-3 

 feet high. We have not seen the cauline leaves, which are apparently ca- 

 ducous ; those of the branches are clothed with long and very soft hairs, thick- 

 ly spreading from the margin, so as almost to resemble the foot of a hare ; 

 whence the name. 



140. ANISOCARPUS. Null, in trans. Amer. phil. soc. I. c. p. 388. 



Heads many-flowered ; the ray-flowers about 12, ligulate, pistillate, in a 

 single series ; those of the disk tubular, staminate and pistillate, but sterile 

 by the abortion of the ovary. Scales of the subglobose involucre as many 

 as the rays, carinate-complicate, and wholly enclosing their achenia. Re- 

 ceptacle somewhat convex, naked and smooth, except the margin, which is 

 furnished with a single series of more or less united chaff}' scales between the 

 ray and disk-flowers. Tube of the corolla pubescent. Rays exserted, cunei- 

 form, 3-cleft at the apex. Branches of the style in the disk-flowers sub- 

 ulate, very acute, minutely hispid. Achenia of the ray oblong, obcompress- 

 ed, flat, somewhat incurved, glabrous, without lateral angles or nerves, 

 crowned with a small sessile disk, destitute of pappus ; of the disk abor- 

 tive, with a pappus of 5-8. small fimbriate-lacerate membranaceous scales. — 

 A villous-hirsute perennial herb, with the aspect of iMadia, or Madaria; the 

 leaves linear, elongated, entire or denticulate, sessile, alternate, or the lower 

 opposite. Heads paniculate-corymbose or racemose ; the involucre, naked 

 jied uncles, and upper part of the stem very glandular. Flowers bright 

 yellow. 



A genus intermediate between Madaria (with which it accords in aspect, and from 

 which it chiefly differs in the pappus of the disk-flowers), and Hartmannia, DC. 

 (§ of Hemizonia), from which it is distinguished by the flat compressed achenia, 

 entirely enclosed in the involucral scales. 



A. madioides (Nutt. ! 1. c.) 



Banks of the Oregon, among rocks, in shady forests, at the outlet of the 

 Wahlamet ; rather rare, Nuttall! — Stem simple, 1-2 feet high, hirsute with 

 long and short hairs. Radical leaves linear-oblong, remotely serrulate, 3-4 

 inches in length; the cauline gradually reduced in size. Involucre 3-4 lines 

 in diameter : rays conspicuous, but rather short. — We have not seen the mature 

 fruit.

Heads many-flowered ; the ray-flowers 10-15, ligulate, pistillate, in a 

 single series; those of the disk tubular, staminate and pistillate, but sterile by 

 the abortion of the ovary. Scales of the subglobose involucre as many as the 

 rays, complicate and enclosing their achenia. Receptacle somewhat convex, 

 fimbrillate-hirsute, except the margin, which is furnished with 1 or 2 series of 

 chaffy scales between the ray and disk-flowers. Corolla pubescent or hairy 

 at the base ; the rays twice the length of the involucre. Achenia of the ray 

 as in Madia; those of the disk abortive; all destitute of pappus. — Annual 

 (Californian) hairy and glandular herbs, with the aspect of Madia ; the heads
