A species extremely near to the Convolvulus mucrojiatus, 

 first recorded by Forster as native of the island of Tanna, 

 in the South Sea; but afterwards, in his account of the 

 vegetables collected by himself at the Cape Verd and other 

 islands in the Atlantic (see Comment ationcs R. S, S. Gottin- 

 gemis) as natural to St. Jago. The last place is that in- 

 scribed on his sample, and on his drawing in the Uunksian 

 Museum, where it is found under the title of acuminatus, 

 which was changed upon publication. Samples, now pie- 

 served in the above Museum, have been collected subse- 

 quently in the same quarter by Sir George Staunton, and 

 this is," we have no doubt, that whence Forster really brought 

 the plant, not from Tanna. The species comes likewise near 

 to the Ipomcea pendula of Mr. Brown's Prodromus of the 

 Flora of New Holland But independently of difference 

 in the general port of the plants, the present is distinct, 

 in having a foliage without any traces of being cihate; in 



having 3-4-floweied peduncle; and by a corolla that is
