in that of their foliage, and the segments of the limb being 

 of a different form in each. As this point however cannot 

 at all events be satisfactorily decided without a mutual 

 comparison of their samples, we have placed the two dis- 

 tinctly under the same specific head.

TuLiPA and Colchicum have no recorded representatives 

 in America, nor within the tropics of either continent. 

 The two appear to be nearly coextensive in their distribu- 

 tion, and limited to the temperate regions of Europe and 

 the confining regions of the North of Asia and Africa. 

 The southern part of Russian Tartary seems to be the main 

 hive of the Tulips. 



Melanthium, perhaps too artificially separated from 

 TuLiPA and to which Tulipa breyniana has only recently 

 reverted, appears to be restricted to the Cape of Good 

 Hope. 



Helonias is the nearest co-ordinate type yet found in 

 America. 



* This species was taken up by Ijnnseus from a letter of Loetling^s, who 

 describes the flowers and leaves as appearing together in the autumn ; whereas, 

 as Mr, Dryander observes, Clusius speaks of his plant as producing the 

 flowers before the leaves, which however come up immediately after, during 

 the autumn, and do not await, as usual in the genus, the spring, but grow on 

 through the winter. A difference which, according to Mr. Dryander, makes 

 the synonym from Clusius doubtful.
