but from a faded specimen, in the Botanical Magazine, pi. 1655. Arclopus 

 eMnatus: the male plant, and the only species of the genus yet known- 

 Musa rosacea Willd. : fully illustrated by two plates, and by some interesting 

 observations of Mr. Brown on the locafities and probable species or varieties 

 of this tribe. Sanvitalia prociimbens Willd.: subjoined to the description are 

 the characters of the three sub-genera or sections of Helianlhus proposed by 

 M.Cassini. Such notices are both interesting and useful to English botanists, 

 wiio have seldom opportunities of seeing or consulting the foreign journals. 

 PI. 708 represents a new variety of the Camellia japonica, named Itdeo-a bi- 

 cans, or Basington's new Camellia ; it has recently been introduced, and ap- 

 pears, as yet, "confined to the collection of the person whose name it bears. 

 Arthrapodium cirratum Brown {Anthericum cirratitm Willd.) : a delicate and 

 very elegant plant from New Zealand. Symplocos sinica : a new species re- 

 cently brought from China. " S. foliis elliptico-lanceolatis utrinque pubes- 

 centibus subcorrugato-venosis : foliolis calycinis acuminatis." 



Czirtis's Botanical Magazine. No. 436. 

 PI. 2398. Mamnta angustifolia, an undescribed species from Trinidad. 

 " M. culmo nodoso, foliis lanceolatis basi angustatis, panicula flexuosa, 

 bracteis internis coloratis, calycibus ovatis." While on the subject of this 

 tribe of plants, we take an opportunity of acquainting the botanical world, 

 that Mr. Roscoe (as it is understood) will very soon publish a further 

 illustration of this valuable and truly elegant tribe. Whether employed in 

 recorchng the history of past ages, or the philosophy of the living beauties 

 of nature, his powerful genius shines forth ; and the name of Roscoe 

 would scarcely need any other record than his luminous observations on the 

 Scitaminece. Aman/llis cyrtantho'ules, a beautiful addition to this lovely tribe 

 received last yeai- from Chili. "A. spatha multiflora, pedicellis cernuis, co- 

 rollis infundibuliformi-canipanulatis, genitalibus strictis exsertis, foliis lora- 

 tis obtusis." Flaveria cuntrat/erba Willd. Stapelia barbata Willd. : belong- 

 ing to Mr. Haworth's genus Huernia. Erigeron bellidlj'vlium Willd. CEno- 

 thera odorata (the OS. uicdulata of Hort. Kew.). Scizanthus 2nnnatus Fl. Per. : 

 the description of this plant in Fl. Per. is stated to accord with the sample 

 here figured, but the plate in that work appears to be defective. Calceolaria 

 scabiosicfolia of Roem. : Dr. Sims thinks this to be the C. pinnata of the Floret 

 Peruviana, but not the C. junnata of the Horttis Kewensis.
