Leplosyne. COMPOSITE. .,-V, 



longer erect scales. Receptacle Hat ; its chaff thin and scarions, linear or lanceolate, 

 deciduous with the fruit. Hays mostly broad and truncate, obscurely 3 - 4-lobed 

 or crenate, many-nerved. Disk-corollas with a short-bearded or beardless ring at 

 the summit of the slender tube; the dilated limb 5 lobed. Style-branches of the 

 ray-flowers often short and included; of the disk-flowers tipped with a very short 

 cone or nearly truncate.' Akenes obcompressed, flat, oval or oblong; those of the 

 ray broader, glabrous or nearly so, more or less wing-margined; those of the disk 

 wingless, villous or ciliate, coherent at base with the subtending appressed chaff. 

 Pappus of the ray none, of the disk a pair of long bayonet-shaped chaffy awns, little 

 shorter than the corolla. — Glabrous annuals, all Californian ; with alternate leaves 

 once or twice pinnately parted into linear lobes, and showy heads of golden-yellow 

 flowers, terminating long naked peduncles. — Gray, Proc. Am. Acad. viii. G59.

This genus and the next take the place of Coreopsis in California. 



CoKEorsis Atkixsoni \\a, Dough, the only species known to occur west of the Rocky Moun- 

 tains. — a species which resembles the well-known C. linctoria of the Arkansas region, common 

 in all gardens, — belongs to Oregon, ami may be expected in the bordering part of California. 



1. P. calliopsideus, < l-ray. A foot or two high, leafy below : lobes of the leaves 

 linear : head large: scales i.if the outer involucre ovate, united at base: rays obovate 

 cuneiform : ray akenes with a thin winged margin ; those of the disk clothed with 

 very long villous hairs on the margins and inner face. — Agarista caUiopsidea, DC. 

 l'rodr. v. 5G9. Coreopsis caUiopsidea, Bolander, Cat. PL .San Francisco. 



Moist hillsides and plains, from the Bay of San Francisco southward. Variable in size: rays 

 from half an inch to an inch long, ami from 4 to 10 lines wide. Disk-corollas with a short- 

 bearded ring on the tithe. 



2. P. Breweri, Gray, 1. c. Much smaller than the preceding, with finer divis- 

 ions to the leaves : scales of the outer involucre linear : rays rather narrow : akenes 

 of the disk long-villous on the margins and the middle of the inner face, otherwise 

 glabrous : chaffy awns of the pappus stouter, only half the length of the akeue. 



Dry hills near 8an Buenaventura, March {Brewer) ; San Bernardino desert, Parry. Rays half 

 el two thirds of an inch long, 'd to 1 lines wide : disk-eorollas with a beardless ring. Bay akenes 

 nearly as in the next; those of the disk more like those of the preceding, except in their smaller size. 



3. P. Bigelovii, Gray, 1. c. A span high, leafy only at the base: the small 

 head on a 1 1 ■ 1 1 1 > naked scape : leaves almost simply pinnately parted into a few 

 narrowly linear rather fleshy divisions j scales of the outer involucre broadly linear: 

 rays broad : ray-akenes narrowly oblong, roughish, and with thickish wing-like 

 margins; those of the disk slightly ciliate. 



Dry plains, on Mohave Creek (Bigelow) and FortTejon, Dr. 5 t. Theplanl from San Buena- 

 ventura, inadvertently referred to this species in Proc Am. Acad. v. 645, is the pr ding. 



The head of this only half as large. Hays quadrate-oblong, l or S lines in length. Ring on the 



i el i disk-corollas distinct buf beardless. Akenes of the di>k inclined to lie sterile ; but this is 



also tl ase in the first species. 



52. LEPTOSYNE, DC. 



Ibel many-flowered, heterogaraous ; the rays several or numerous, pistillate; 

 disk-flowers perfect, [nvolucre double; the outer of 5 to 8 narrow and loose folia- 

 ceous scales ; the inner of 8 to L2 erect more membrane -. Receptacle 



nearly Hal : its chaff thin and ssarious, linear or lanceolate, deciduous with the 

 fruit. Rays oblong or obovate, 3-toothed or lobed at the end. 10-nerved. Disk-
