in diameter, the tube is somewhat narrowed at its base and in the 

 throat ; the antheriferous free ring arises in the constriction of 

 the tube. It is possible that in the specimen referred to^ the 

 flowers are only in a young state^ and that when fully grown 

 they may assume a somewhat greater development, but I give the 

 description in accordance with the specimen as it exists*.

SOLANDRA. 



I notice this genus, in order to confirm what has been already 

 advanced respecting it in the preceding volume of this work 

 p. 176, when I endeavoured to show that its relation is decidedly 

 with Juanulloaj Marckea and Sarcophysa^ constituting with these 

 genera a distinct tribe of the Atropacei2 or AtropinerSy and in no 

 degi'ee related to Datura, with which it has been classed by all 

 botanists heretofore. It will be seen to approach JuanuUoa in 

 its large tubular calyx, which splits generally on one side, in 

 consequence of the growth of its large fleshy berry, in the struc- 

 ture of which there exists a considerable resemblance in both ge- 

 nera^ but it differs from that genus, in its much larger and more 

 campanular corolla. It bears also great analogy with Brumfelsiay 

 in its large, yellow, fleshy border, with five rounded lobes, greatly 

 fimbriated on their margins, and deeply imbricated in estivation, 

 and also in its large berry filled with pulp ; but it differs from this 

 last-mentioned genus, in its general habit and in the structure of 

 its stamens. It will serve to connect the Solandre(2 with the 

 BrumfehiecB , and in the linear arrangement shown in the tabular 

 view, p. 166, as above quoted, it should have been placed below 

 Edozoma, and immediately preceding Brunsfekia. I have not 

 been able to examine its seeds or to find any analysis of its struc- 

 ture, any farther than that the embryo is said to be arcuate; in 

 this respect it will probably resemble JuanuUoa^ Marckea and 

 Franciscea, where it is terete, nearly straight or only slightly' 

 bent, with short, ovate cotyledons. The following is offered as 

 an amended generic character : 



SoLANDBA, Swartz. (Char, emend.) — Cali/a; 5-sepalus, per- 

 sistens ; sepala lanceolata, acuta, marginibus in tubum longum, 

 cyliiidraceum, 5-angulatum, injequaliter et breviter 2-3-par- 

 titum, deraum hinc fissum, valvatim conniventia. Corolla 

 magna, inferne valde coarctata, carnosa, cylindracea, 5-gona, 

 superne ventricoso-campanulata, crassa, 5-nervis, venis anasto- 

 mosantibus, limbo 5-partito, laciniis revolutis subsequalibus 

 rotundatis margine inciso-^crispatis, sestivatione valde imbri- 

 catis. Stamina 5, sequalia, ad constrictionem tubi inserta,
