Donations to the library were announced from the Entomological 

 Society of London, the Horticultural Society of Berlin, and Mr. Town- 

 ley. 



Mr. Hewett Watson exhibited some of the specimens which had 

 been received by the Society in the valuable parcels of Azoric plants 

 from their active and esteemed fellow-member Thomas Carew Hunt, 

 Esq., of St. Michaels, Her Majesty's Consul for the Azores. Upwards 

 of forty species have already been added by Mr. Hunt to the list of 

 Azoric plants, enumerated by Mr. Watson in his account of the 

 Botany of these isles, published in 1844. In the last parcel received 

 from Mr. Hunt, early this year, there were a few specimens of 

 Trichonema Columna, thus adding another point of similarity between 

 the flora of these isles and that of the South-western counties of England. 

 As far as they have been satisfactorily determined, all Mr. Hunt's 

 additional species (certainly native in the Azores) are described 

 natives of the other Atlantic isles (Madeira and Canary) or of South 

 Europe, with one exception, namely, a species of Ammi, which is 

 unlike any of those described in the Prodromus of De Candolle, but 

 has the peculiar involucre and the fruit of that genus, as it stands in 

 the work mentioned. Mr. Watson was desirous of recording this 

 new species by the name of its discoverer, who had kindly sent 

 a large supply of duplicates for distribution, imder the impression of 

 its being a novelty. He was more anxious to attach Mr. Hunt's 

 name to this plant, because it forms one more in a small group of 

 umbelliferous plants which are characteristics in the Azoric Flora, 

 and which much resemble one another, although unfortunately 

 referrible to three or four different genera, according to the generic 

 arrangement of the species of that order at present in use. One of 

 these he had himself described in the ' London Journal of Botany ' 

 under name of Petroseliuum trifoliatum. A second species probably 

 belongs to the same genus, and has foliage intermediate between the 

 Petroseliuum and the new Ammi ; but as Mr. Watson possesses only 

 one immature specimen, he is unable to determine its generic 

 character. A third species is the No. 100 of Mr. W.'s own collection 

 and printed list of Azoric plants, which also remains undetermined, 

 though apparently neither an Ammi nor a Petroselinum. A fourth 

 species is the new one from Mr. Hunt, and which Mr. Watson 

 proposes to distinguish from Ammi majus, by the following character 

 and short description : — 



Ammi Huntii {Wats. MSS.) Caule glabro striato, foliis ternato- 

 pinnatis bi-tri-pinnativisve, foliolis elliptico-lanceolatis margine carti-
