253 Mr. J. Miers on the genus Cacabus. 



along the tube ; the stamens and style are exserted 1 J inch be- 

 yond the mouth of the tube, the anthers being 6 lines long and 

 a line broad ; the style thickens towards the summit, and is ter- 

 minated by a stigma formed of two adpressed lobes, lined within 

 by a thick viscous gland ; the ovarium is about 3 lines in dia- 

 meter and 3 lines in height, quite conical, and seated on a large 

 fleshy and coloured gland.

 ^ Endl. Fl. Bras. vi. 159; TValp. Rep. vi. 573; — fruticosa, 

 glabra, foliis congestis, glabris, utrinque acutis, integer rimis ; 

 floribus nutantibus ; pedicellis calycem subsequantibus, vel su- 

 perantibus, fructiferis valde elongatis : calyce 5-partito ; corolla 

 infundibuliformi, e basi sensim dilatata, limbo breviter 5-fido, 

 laciniis acutis revolutis : stigmate longissimo spatio in stylum 

 decurrente. — Brasilia austrah. 



The above is all the information I have been able to obtain of 

 this species : it will be seen to differ in no respect from the pre- 

 ceding one (as far as we may judge from the foregoing characters) 

 except in the shorter lobes of the corolla : the gradual dilatation 

 of the corolla, without any sudden ventricose enlargement, is 

 very often seen in D. viridiflora. 



Cacabus. 



This genus was first proposed by Bernhardi for a Peruvian 

 plant of Dombey's collection, which was many years before ac- 

 curately described and figured by L^Heritier (Stirp. Nov. Angl. 

 p. 43. tab. 22), under the name of Physalis prostrata, and which 

 appears to have since escaped farther notice : I find other spe- 

 cies allied to it, which are all distinguished by their inflated calyx, 

 generally of very delicate texture, remarkably reticulated, marked 

 by dark green lines and veins, and which, swelling after the fall 

 of the flower, eventually incloses the fruit, as in Physalis and 

 several other genera. They have all herbaceous stems, are of a 

 prostrate or straggling habit, and they bear a very striking re- 

 semblance to Nolana, especially in their fleshy flexuose branches, 

 often geminate leaves, large campanular blue flowers, with a 

 somewhat pentangular border, and marked with fifteen longitu- 

 dinal nervures, as in that genus : the stamens are also included 

 and somewhat unequal in size : indeed so near is this similarity 

 in external appearance, in one species, that I have constantly 

 passed over, without suspicion, a specimen of Mathews^s collec- 

 tion, named by him " Nolana spathulata, 11. & V." which I did 

 not consider it necessary to examine, as it was not in fruit. 



There exists in Sir William Hooker's herbarium, a plant be- 

 longing to this genus, which appears to correspond well with the 

 description of the Nolana injlata of the ' Flora Peruviana,' a spe-
