carpellis 3-5 ovatis brevistylibus 2 - 4-ovulatis ; seminibus rugulosis. 

 — A most distinct and mucb tbe largest and handsomest species of 

 this genus ; the flowers individually about as large as those of I. biter- 

 natum, but 6 to 10 together in an umbelliform often once or twice bifid 

 cyme, and with the very numerous and conspicuous filaments as white 

 as the sepals, and resembling those of Trautvetteria. 



11. Caltha leptosepala DC. In flower and fruit. 



12. Coptis asplenifolia Salisb. In fruit. 



13. Aquilegia Formosa Fischer. Whether to be regarded as a 

 variety of A. Canadensis is uncertain. 



14. Delphinium Menziesii DC. The seeds will clearly distin- 

 guish all forms of this from the Eastern D. tricome. 



15. Delphinium trolliifolium, n. sp. Subglabrum vel tenuiter 

 pilosulum ; caule laxo (bipedali et ultra) ; foliis sparsis longe petiolatis, 

 petiolis basi subdilatatis, lamina circumscriptione orbiculata profunde 

 5 - 7-fida, segmentis cuneatis trifidis pauci-incisisque, lobulis obtusis 

 (mucronulo calloso quasi truncato apiculatis) ; racemo sparsiflora per- 

 laxo ; pedicellis adscendenti-patentibus, inferioribus pnesertim elonga- 

 tis ; calcare sepalis petala superantibus longiore ; petalis superioribus 

 integris albis, inferioribus subquadratis emarginato-bifidis erosis vel 

 crenato-dentatis ; folliculis oblongis glabris laxe reticulatis demum 

 recurvo-patentibus ; seminibus vertice scarioso-coronatis. Leaves in 

 the dried specimens thin, 2 or 3, or the largest 4 or 5, inches in diame- 

 ter, in outline and division reminding one of Trollius. Lower pedi- 

 cels 2 or 3,*or in fruit sometimes 4, inches long. Flowers blue, except 

 the upper petals : spur three fourths of an inch long. 



16. Act^ea spicata L. var. rubra Michx., the A. arguta Nutt. 



17. Cimicifuga (Pitysosperma) elata Nutt. in Torr. & Gray, 

 Fl. 1, p. 36. C. fcetida Pursh, non L. This is exactly a Pityrosper- 

 ma of Zuccarini, and apparently between P. acerinum (which only I 

 have a specimen of) and P. biternatum. In the whole structure of 

 carpels (from one to three in number) and seeds it well unites Macro- 

 tys with Cimicifuga proper. 



18. Berberis (Mahonia) Aquifolium Pursh, Fl. l,p. 219, t. 4. 



19. Berberis (Mahonia) nervosa Pursh, 1. c. t. 5. 



20. Vancouveria hexandra Decaisne. Epimedium hexandrum 

 Hook. Fl. Bor.-Am. t. 13. The ovules, commonly "8-10," are 

 sometimes as few as three, or even two, at least in Californian speci- 

 mens.
