uEScRiPTioN or CUniSTYA. 135 



composed of 5 connate sc&les; the corolla tube is narrow, 

 and not longer than the calyx, and its lobes are not longer 

 than the tube; the coronal squamse are laterally compressed, 

 included, projecting across the tube, and undivided ; the 

 anthers do not cohere by their edges, though they form a cone 

 round the stigma ; and, moreover, they are produced at the 

 tips into long, bearded acuminations : the style is short, and 

 the stigma, which Meyer calls peltate, I find to be capitate, 

 5-angled, with a bifid, subulate acumination. 



The existence of fleshy scales within the calyx, though 

 mentioned but in few genera of tlie order, seems to be of 

 frequent occurrence ; and perhaps these bodies ai"e present 

 in some form or other in all cases where there are no hypo- 

 gynoiis discs or scales. 1 find them in the Cape Arduims 

 in the form of a ring of unequal, subulate, fleshy bodies, en- 

 circling the base of the calyx, not " a many-toothed hypogy- 

 nous disc," as incorrectly stated in my " genera," p. 231. In 

 " Voacanga Dregei,'* E. M., I find the lower part of the 

 tubular calyx muricated on the inside with several rows of 

 fleshy scales. This plant does not appear to be a true spe- 

 cies of Voacanga, but seems much more nearly allied to 

 Orchipeda of Blume, if it be distinct from it; but as I am 

 unacquainted with Blume's plant, and the description does 

 not quite accord, 1 propose to call our African species Piplo- 

 ItETia, in allusion to the deciduous calyx.* In another new 

 Cape genus, Toxicophlcea, founded on Cestrum venenatum of 

 Thunberg, there is an obsolete crenate disc, exterior to the 

 corolla, and covering the base of the calyx. In Gonioma 



* It is rather a curious circumstance, that though tJiree species of Ces- 

 trum have been attributed to the Cape Flora, not one of them belongs either 

 to Cestrum, or to the SolanacecB ; nor do any two of them belong to the 

 same natural order. C venenatum, Thunb., constitutes, as above noticed, 

 a genus of Apocynece of the section CarissecB with solitary ovules, by which 

 and the other characters, it diflfers from all the other genera of that section. 

 C dubium of Sprengcl.in Herb. Zeyher, which is the same as Grumilia, 

 2360, and of Drege's plants, is an Ehretia (E. capensis, H.); and lastly, but 

 surely not /ea*'? of these extravagant blunders, C. umbellatum of E, Meyer, 

 in Herb. Drege, is Peddiea Africana. W. H. H.
