of its relatives, differing considerably in aspect by the oblong or 

 elliptic-oblong leaf-blades. However, the crucial character that 

 separates it from all of its relatives is the three-lobed lip. The 

 original specimens were collected by Mr. J. H. Simpson, at Fort 

 Meyer, Florida, December n, 1891, no. 368. 



OXALIS HIRSUTICAUL1S. 



Perennial from horizontal rootstock, bright green. Stems 

 erect, 1-2 dm. tall, simple or nearly so, stout, densely hirsute, 

 scaly at base : leaves rather numerous ; petioles usually 4-10 cm. 

 long, villous-hirsute : leaflets 3, strigillose or glabrate in age, 

 1-1.5 cm. long, sharply notched, thickish ; peduncles erect 

 or nearly so, surpassing the subtending leaves, pubescent like 

 the petioles, topped by umbel-like cymes : pedicels usually 

 1.5-2 cm. long, subtended by narrow bracts: sepals 5-6 mm. 

 long, various ; outer oblong, inner linear-oblong, all ciliate, thin, 

 obtuse : petals golden yellow, 1.5-2 cm. long, glabrous through- 

 out : filaments pubescent : styles villous-hirsute : capsules colum- 

 nar, about 1 cm. long : seeds 1 . 5 mm. long, with low, transverse 

 ridges. 



In open woods, near Nashville, Tennessee. 



For several years I have hesitated to publish this excellent 

 species although to thrust it into any of the species to which it is 

 related does violence to the clear lines separating those species 

 from one another. On the one hand it is related to Oxalis mac- 

 rantha, but diners in its upright habit and the copious spreading 

 pubescence, on the other hand it can be compared with Oxalis 

 recurva, but it is very much more robust, its pubescence is of a 

 hirsute type rather than villous, then, too, the inflorescence does 

 not conspicuously surpass the leaves and the styles are not re- 

 curved in the characteristic manner in which those of Oxalis re- 

 curva are. 



The original specimens were collected by Dr. A. Gattinger in 

 the vicinity of Nashville, Tennessee. Besides specimens in the 

 Herbarium of Columbia University I have had the use of ample 

 specimens from the Herbarium of the University of Tennessee,
