elongated petals drying green; V. Califdmicum, on the contrary, like Melantliium 

 virginicum, dries purple, and has ovate sepals, marked at the base with a deep 

 brown spot. The bracts in V. viride are very long and narrow, those of V. Califor- 

 nicwn are scarcely longer than the short pedicel, and are oval and concave ; the leaves 

 also are quite different; they are broadly ovate in the former, and oval-lanceolate 

 in Mr. Pratten's plant.
