bour. — It must have been through some mistake that, in the Flora of 

 North America, this species was placed in the section with an adherent 

 ovary. 



2. LiTHOPHRAGMA TENELLA, Nutt. Glanduloso-hirsutula ; foliis 

 minus dissectis ; pedicellis calyce primum obconico dein carapanulato 

 tequilongis ; ovario infra medium adnato ; seminibus lasvibus. — Rocky 

 Mountains. The only specimens are the original, scanty, and appar- 

 ently depauperate ones of Nuttall. The plant resembles a diminutive 

 L. parvijiora, with less divided leaves, and a campanulate calyx, the 

 base of which is certainly adnate to the lower part of the ovary. The 

 seeds are much smaller and oval. 



3. LiTHOPHRAGMA PARViFLORA, Nutt. (Tellima parvijlora, Hook. 

 Fl. Bor.-Am. 1. p. 239, t. 78.) Scabro-hirta ; pedicellis suberectis 

 calyce obconico (fructifero nunc clavato) creberrime glanduloso-hirtello 

 saepius brevioribus ; ovario ultra medium adnato ; seminibus l^vibus 

 oblongis. — Rocky Mountains and Oregon, to Vancouver's Sound. 



The plant referred to this species in Ives's Colorado Expedition, col- 

 lected by Dr. Newberry on hills along Cedar Creek, in the western 

 part of New Mexico, is, from the calyx, «fec., more like L. tenella on a 

 larger scale, but probably is of a different species, not to be made out 

 satisfactorily with the extant materials. It bears some granules or 

 bulblets on the base of the stem, which have not been detected in any 

 of the following species. 



* * Petala lamina dilatata triloba, raro Integra : folia radiculia reni- 

 formi-rotundata subindivisa vel crenato-lobata, superiora 3-5-fida 

 vel partita : bulbilli ad radices, etc., nulli. Flores majusculi. 



4. LiTHOPHRAGMA AFFiNis, sp. nov. Scabro-hirta, 1 - 1^-pedalis; 

 floribus modice pedicellatis; calycis creberrime glanduloso-hirtelli tubo 

 turbinato ad apicem fere ovarii adnato ; stylis granulosis ; petalis 

 maxime dilatatis apice trilobis ; seminibus Isevibus. — This has been 

 confounded with L. heterophylla, and it is apparently as common in 

 California around and north of San Francisco, where Dr. Brewer has 

 abundantly gathered it, at several stations. To it belongs the speci- 

 mens (named L. heterophyUa) collected by Dr. Bigelow in Whipple's 

 Expedition, a part of Dr. Parry's, collected at Monterey, in the Mexi- 

 can Boundary Survey, Thurber's fi'om Napa County, and specimens 

 from Ross, long ago distributed by the St. Petersburg Academy. 

 It is at once distinguished from the next by the calyx tapering to an
