face glaucous, both faces (at least, there is not an expression to 

 restrict it to one) covered with a thick, horny, and in some de- 

 gree scurfy, epidermis. Scape 2 ft. high, bearing the flowers in 

 its upper part and scatteredly ; eleven are shown in Bot. Reg., 

 August : in Edin. New Phil. Journal, July, they are stated to be 

 about twelve : they are sessile, each in the axil of a bractea. Calyx 

 and corolla of a full orange colour ; calyx three-parted ; corolla 

 three-cleft, twice as long as the calyx; the three segments united 

 at their base with the calyx ; spreading at their tip, and disposed 

 into a tubularly bell-shaped corolla, the length of which and 

 of the calyx together is nearly an inch. Anthers and upper 

 part of stamens obvious in the mouth of the corolla. Ovarium 

 included within the calyx and corolla not positioned under them, 

 many-seeded. 



Dyck/a rariflora is " very handsome." (Dr. Graham, in Edin. 

 N. P. J.) " The dry stove seems to suit it, for there it produces 

 its rich orange flowers in great perfection, and retains them in all 

 their freshness and beauty for several weeks." It " propagates 

 very slowly, after the manner of an aloe." It " is a native of 

 the Serra of Villa Rica, in Brazil, where it and two more species 

 were discovered by the indefatigable travellers Spix and Martius." 

 (Dr. Lindley, in Bot. Reg., August ; where interesting informa- 

 tion on the anatomy of the leaf of the D. rariflora is, besides, 

 supplied.) D. rariflora was received into the collection in the 

 Edinburgh Botanic Garden in 1832; into the collection of the 

 London Horticultural Society in 1833 ; into both collections 

 from that of the Berlin Botanic Garden. (Bot. Reg., August ; 

 Ed. N. P. J., July.)

 the Continent 'of Europe, under the name of O. simia; but a 

 careful comparison with the rare O. tephrosanthos of the south 

 of England will show that, notwithstanding its greater size and
