Ruth sent me mature specimens of the hitherto imperfectly un- 

 derstood form which I have just described. The leaflets of the 

 species bear a strong resemblance to those of Caulophylhtm thal- 

 ictroides, whence the specific name. In this respect they differ 

 from those of the nearest relative, Thalictntm coriaceum. The best 

 character, however, exists in the fruit which is larger and narrower 

 than that of T. coriaceum. The style is one-half as long as the 

 achene or shorter and is club-shaped, thus differing from the longer 

 style of its relative, which is subulate at maturity. The type 

 specimen was collected by Prof. Ruth on mountain sides, Cade's 

 Cove Mountain, Tennessee, July, 1892, number 1800. 



^ Capnoides Halei. 



Stem branched at the base 



branches spreading or ascending, 1-3 dm. long, simple or sparingly 

 branched: leaves glaucescent beneath, the lower ones with petioles 

 longer than the blades, the upper ones sessile, all dissected ; seg-

***v.iico latiici i,udioi,, cn~cic^ . * t*^*-***^^ ~ , L - 



bracts ovate to elliptic, acuminate : pedicels 2-5 mm. long, stout : 

 corolla yellow, about 1.5 cm. long, the spur obtuse, much shorter 

 than the body, the outer petals with thin incised-toothed crests . 

 capsules stoutish, 2 cm. long, straight, erect or nearly so, on short, 

 almost erect pedicels. 



In dry soil, Florida to Louisiana. Spring. 



Specimens of the species here described were collected many 

 years ago in Louisiana by Dr. Hale, and lately Mr. Curtiss has 

 distributed excellent material from the vicinity of Jacksonville, 

 Florida, representing his number 45 « 5. at least in part. 



Capnoides Halei "is most closely related to Capnoides curvmUqmnn 

 from which it may easily be distinguished at sight by its more 

 slender habit, and especially by the more coarsely dissected leat- 

 blades ; the corolla is of a much less brilliant yellow and the spur 

 is much shorter than the body, whereas, in Capnoides cHmsOtquuM 

 the spur and body of the corolla are equal in length. The capsules 

 are erect or nearly so and straight as compared with the curved 

 pods of its relative.
