Pedis papposa, Gray, which very much abounds in large dotted glands 

 throughout, especially on the leaves (1-2 inches long, %-line wide), mucro- 

 nate, often slightly connate at base — opposite lower branches and similar por- 

 tion of the stem purplish — slender peduncles enlarged near the base of the 

 heads, sulcate corresponding to the 6-9 involucral scales which are dotted 

 with 1-2 large glands on the back at the tips, margins involuted, but not sca- 

 rious, infolding the ray akenes in their channels. These rigid, yellowish- 

 green scales are rounded abruptly at the base and laterally attached; orauge 

 rays same in number, but longer, their akenes without pappus, or only a very 

 minute united scaly crown; pappus of the disk of 20-25, tawny, rather long, 

 unequal barbellate bristles similarly cohering. 



An exceedingly beautiful and delicate pink-purplish morning-glory, brought 

 by Mr. Wm. J. Fisher from Ajiabampo, of the Gulf of California, has very 

 handsomely radiated leaves, adding a new glory to these very beautiful twin- 

 ers. We, therefore, propose to name it 



Ipomoea radiati folia. K. 



Stem slender, twining or creeping, 2-4 or more feet high, glabrous, some- 

 what petangular, fistulous; leaves alternate, or more rarely opposite, pedately 

 5-12-parted, lobes linear, filiform, mucronate, msirgins thickened and entire, 

 lateral lobes subdivided into 2-4 outer lesser lobes (giving the leaves a deli- 

 cate, airy, rounded, radiating outline), petioles slender, 1% inches long (or 

 shorter than the longest middle, and distinct lobe), muricated (no stipules) ; 

 peduncles 1-flowered, axillary, 2-3 inches long, articulated %-inch or more 

 below the calyx, bibracteolate at the insertion of the pedicel, bracteoles mi- 

 nute, subulate, scabrulose at the joint; calyx 5-sepaled, equal, naked, nar- 

 rowly lanceolate-linear, acuminate, thin, 3-nerved, margins scarious, suben- 

 tire; corolla purplish-pink, broadly funnel-form, 1-2 inches diameter, tube 

 gradually enlarging to the throat of the widely expanded campanulate border; 

 stamens and style included, unequal, filaments hirsute to the oblong saggitate 

 anthers (scales none), style long, glabrous, stigma 2-lo^ped, semicircularly 

 fan-shaped, often subdivided into minute lamellary lobules, minutely villous; 

 Eoot and mature fruit unknown; embryo 2-celled, smooth. 



Pacific Coast L-epidoptera, No. 22.— Notes on some Diurnal 

 Lepidoptera, with descriptions of sew varieties. 



BY HENRY EDWAEDS. 



Mr. W. H. Edwards, of Coalburgh, West Virginia, has in view the speedy 

 publication of a complete check list of North American butterflies, and it has 

 been suggested by him that all facts connected with the group known to ob- 

 servers in different parts of the region comprised by the work, should at once 

 be published, so as to bring together such information as may, if deemed 

 worthy, be incorporated in the more important publication. With this view 

 I have made the following notes on some doubtful or little-known species, at 

 the same time calling attention to such strongly marked varieties of some of
