7. C A L T H A, Linn. 



1. Caltha bifloea, DC, Hook. 



Hab. Wet places near the Cascade Mountains, Oregon. — Stems 

 slender, 1-2-flowered, usually bearing a single small leaf, but some- 

 times naked. Leaves reniform, conspicuously crenate, the radical 

 ones on a long petiole, the basal sinus almost closed. Flowers about 

 half as large as those of G. palustris, with oblong sepals ; the 4-9 

 carpels slightly acuminate with the very short style. Sir William 

 Hooker thought this species might be too nearly allied to G. lepto- 

 sepala, DC. ; but in these specimens it appears to be very distinct. 



8. TROLLIUS, Linn. 



1. Teollius laxus, Salisb. 



Hab. Washington Territory ; common in subalpine prairies near 

 the Columbia River. — Smaller than the Eastern plant, but not other- 

 wise to be distinguished.
