﻿146 Small: Studies in the Botany 



oblong to oblong-obovate, I — 1 . 5 dm. long, rounded at the apex, 

 repand-undulate, smooth, red-nerved above : petioles shorter than 

 the blades, winged, dilated and sheathing at the base : stem-leaves 

 few, much reduced, narrow, serrate : pedicels stout, 5~~ 12 cm - l° n g'- 

 with several deciduous bracts : involucres hemispheric, 2 cm. 

 broad : bracts various, the outer orbicular-ovate, about I cm. 

 long, the inner oblong, about 1.5 cm. long, rounded: corollas 

 6— 7 mm. long: rays yellow, 1.5-2 cm. long, notched at apex: 

 achenes oblong-obovoid, 9-10 mm. long, narrowly winged, 

 notched at the apex. 



In dry sterile soil, Tennessee. Summer and fall. 



I noticed this form as a new species in one of the larger her- 

 baria several years ago. Prof. Ruth now sends newly prepared 

 specimens of the same from Knoxville, Tennessee, where he col- 

 lected them in September 1897, number 4024. 



The new species is related to Si I plum 

 obovate type of leaf-blade with the tapering base is not character - 

 stic of that species. A prominent character exists in the invo* 

 lucre where the outer bracts are broader than long, while in the 

 most closely related species the corresponding bracts are longer 

 than broad. 



^Coreopsis Lewtoxii. 



Perennial glabrous. Stems branched at the base ; branches 

 ascending or slightly decumbent and erect, 3-5 dm. tall, slender, 

 simple, or sparingly branched above : leaves opposite, approxi- 



below, distant above ; blades linear or narrowly linear-cune- 

 ate, 1-3 cm. long, obtuse or acutish : petioles somewhat shorter 

 than the blades, often filiform: peduncles filiform, 1-7 cm. long: 

 involucres 7-8 mm. broad : bracts scarious-margined, outer ovate, 

 1—1.5 mm. long, obtuse, inner oblong or oblong-lanceolate, 5-6 



mate

mm. long, obtuse or acutish : rays yellow, broadly cuneate, about 

 1 cm. long, 3-lobed ; lateral (lobes gradually rounded ; terminal 

 lobes notched : corolla yellow, 2 mm. long, segments recurved : 



mm 



elliptic, 2 mm. long ; wings broad, entire ; awns short. 



In low sandy soil, peninsular Florida. Summer. 



A species related to Coreopsis angustifolia but much more deli- 

 cate in habit. Readily distinguished by the manifestly petioled 

 leaf-blades, the broader and more amply lobed rays and the entire 

 short-awned achenes.
