4. T L M I E A, Torr. & Gray. 



1. Tolmiea Menziesii, Tott. & Gray. 



Hab. Around Paget Sound, in fertile woods ; eastward to the Cas- 

 cade Mountains.— Calyx unequally 5-cleft; the lobes ovate-lanceolate, 

 three of them longer than the others ; tube cleft nearly the whole 

 length between the two shorter lobes. Petals only 4 ; there being 

 none between the two shorter lobes of the calyx.

1. Tellima grandiflora, Dougl. 



Hab. Puget Sound; abundant. — Petals conspicuously exserted, 

 cuneate at the base, the lamina cut into 7 to 9 narrow lobes.

1. Lithophragma PARVIFLORA, Nlltt. 



Hab. Oregon and Washington Territory ; not uncommon in prai-
