﻿166 Scientific Intelligence, 



ished for one hundred and thirty years, he discarded some Tourn- 

 efortian names for reasons which we should now think insufficient, 

 or, as in the case of Datura, he sometimes took up an earlier 

 name. But the names which he then adopted or created were 

 thought to be settled past recall. 



The new departure which we deprecate is quite a different thing 

 from the citation of Tournefort as the scientific founder of the 

 genera which Linnaeus adopted from him, and himself cites as 

 Tournefortian, in which he is followed by most succeeding botan- 

 ists, though not with complete regularity. a. g.

10. Hooker's Ieones Plantarum, the fifteenth volume of which 

 was completed last year, is now carried on with new vigor, we 

 believe by means of a legacy of the late Mr. Bentham. The first 

 part of the sixteenth volume appeared in April last, and the first 

 part of the seventeenth followed in May. It is convenient thus 

 to carry on the two volumes simultaneously, because one of them 

 (the seventeenth) is devoted to Ferns, under the hand of the inde- 

 fatigable Mr. Baker, the other to Phsenogams. Among the latter 

 we note with interest, plate 1514, Asimina insularis, Hemsley, 

 from Corumel Island, Yucatan. In the brief account of it, no allu- 

 sion is made to its affinities ; so one is uncertain whether the 

 author is aware that it is a close congener of Seemann's Sapranthus 

 J\ T icarague?isis, enumerated in Hemsley's Botany of the Biologia 

 Centrali- Americana. Indeed, it seems to be identical with the 

 plant collected (flowers only) on the island of Nicaragua by 

 Charles Wright, and mentioned in our brief monograph of Asi- 

 mina in the Botanical Gazette for July last. Coming from Nica- 

 ragua, we took it for Seemann's species, notwithstanding the much 

 smaller (or much less accrescent) corolla. But the fewer ovules 

 should distinguish it, as well as the difference in size. This Sa- 

 pranthus insularis goes to confirm the genus, which by its equal 

 and similar, thin and plane, and equally accrescent petals, is mani- 

 festly distinct from Asimina. a. g.
