278 Small: North American Plants 



■ 



is only about one-half the size of that of 7] clavatum and has a 

 plump barely ribbed body not at all depressed along the upper side. 

 The original specimens were collected by Prof. F. S. Earle 

 under sandstone bluffs on Little Mountain near Moulton, Alabama, 

 June 25, 1899, no. 2212. 



1/ Phyllanthus Avicularia 



Perennial, bright green. Stems branched at the base and 

 throughout, 3-6 dm. long, puberulent, striate in age : leaves nu- 

 merous, ascending : blades oblong, or slightly broadest above the 

 middle, 8-18 mm. long, blunt or barely pointed, slightly paler 

 beneath than above, rounded or truncate at the base : petioles 1 mm. 

 long, or shorter : calices short-pedicelled ; staminate delicate, barely 

 2 mm. broad, sepals orbicular-obovate or suborbicular : pistillate 

 firmer, fully 2 mm. broad or barely 3 mm. broad at maturity; se- 

 pals oblong or oval, scarious-margined, persistent : capsules sphe- 

 roidal, 3 mm. broad. 



In dry 



Type from Co- 



lumbia, Texas, collected by B. F. Bush, October 26, 1899, no. 263. 

 Related to Phyllanthus polygonoides, but much more robust in 

 all its parts. The leaves, too, are of an oblong type. The cap- 

 sules conspicuously surpass the mature pistillate calyx, whereas 

 those of P. polygonoides are at least equaled by the mature sepals. 



OEnothera nyctaginiifolia 



Apparently annual or biennial, sparingly pubescent. Stems 

 branched at the base, branches spreading or decumbent, 2-5 dm. 

 long, more or less branched : leaves rather few ; blades lanceolate 

 to ovate-lanceolate, 2-5.5 cm - l° n g> acute or slightly acuminate, 

 often somewhat crisped and twisted, undulate, ciliate, cuneate or 

 truncate at the base ; petioles 2-6 mm. long, pale, margined : 

 flowers axillary : hypanthium bristly and with very slender hairs, 

 especially about the ovary ; tubular portion about as long as the 

 ovary: sepals linear-lanceolate, fully 1.5 cm. long, thin and deli- 

 cate : capsules 4-5 cm. long, club-shaped by the sterile basal por- 

 tion which is slightly shorter than the fertile portion, about 4 

 mm. thick : seeds 1.5 mm. long, reticulated. 



In dry soil, Flagstaff, Arizona, September 5, 1894,/. W. Tourney. 



More closely related to OEnothera laciniata than any other 

 species. It differs in the larger flowers and the club-shaped cap- 

 sules, besides the conspicuous character of the leaves. These 

 members are very suggestive of the leaves of Nyctaginea or the 

 broad-leaved species of Allionia.
