3.- P. tenuijlor a -{PnxBh !)— The specimen in Mr. Lambert's herbarium is 

 a very poor one, and the flowers have nearly all fallen off. It is very possi- 

 bly the same with P. obtusiloba, although that species is canescently hairy 

 (when young) and very slightly .glandular ; while Pursh's plant is gla- 

 brous and the glands are conspicuous. 



4. P. longifolia should be stricken out : the synonym is already adduced 

 under Phaca longifolia, p. 346, where it properly belongs. 



8. P.florihunda, and 9. P. ohtusiloha. — Notwithstanding the manifest dif- 

 ference in the calyx between this and the succeeding species, we have speci- 

 mens so nearly intermediate in this respect, that we have good reason to 

 doubt whether P. obtusiloba is more than a variety. The racemes of the 

 latter are however much fewer-flowered, and the leaflets shorter and broader. 

 The fruit of P. floribunda is oval, pointed, not wrinkled, but covered with 

 glandular dots. .The habit of P. obtusiloba is not unlike Baptisia tinctoria ; 

 and we suspect' it may prove to be P. tenuiflora, as remarked above. 



13. P. cryptocarpa is the same with P. aisjndata of Pursh ! {Jl. suppl. 2. 

 27. 741), from " Upper Louisiana," now Missouri, Bradbury ! a species 

 which had by accident escaped our notice ; that name must therefore be 

 substituted. 



14. P. brachiata (Dougl. !) must be united with P. esculehta. The spe- 

 cimen "of Lewis (in herb. Lcmib.) is just the P. brachiata, as figured by 

 Hooker; but is in fruit. The figure of Pursh is taken from a flowering spe- 

 cimen of Nuttall's in the same' herbarium (although Pursh makes no men- 

 tion of having seen any specimen besides that of Lewis), which is only a 

 different state, and scarcely to be distinguished as a variety. 



23. P. rhdrnbifolia should have been placed after P. physodes. 



24. _ P. Onobrychis. — Add syn. Bot. reg. t. 453. — Near Spartanburg, S. 

 Carolina, Mr. E. Rowland ! — Listead of the remark : ' Very nearly to the 

 two preceding species', read : Allied to P. melilotoides and P. eglandulosa. 

 — Add to the character : Stipules linear-subulate. 



24 (a). P. stipulata: nearly glabrous, not glandular; stems ascending; 

 leaves pinnately 3-foliolate ;. leaflets ovate-elliptical, obtuse, mucronulate, 

 longer than the petiole ; stipules ovate ; spikes capitate, on peduncles about 

 the length of the leaves ; . bracts minute, caducous ; calyx much shorter than
