Anthocercis.—I was glad to avail myself of the opportu- nity of investigating the structure of the flowers in this genus from a plant in the living state of A. viscosa. It agrees with the figure given by Endlicher in his ' Iconographia/ tab. 68, of A. littorea, with the exception of the very important feature of the structure of the anthers, which, as in the preceding genus, offer the very distinct peculiarity of being affixed extrorsely just above the sinus upon the filament, so that the lines of dehiscence are towards the tube of the corolla, not inti'orsely towards the centre of the flower, as appears represented in the plate above referred to. The {estivation of the corolla in Anthocercis viscosa is also very peculiar: at first sight it would be said to be induplicato- valvate, but upon more careful examination it will be observed that each lobe of the border is distinctly supervolute, one of its edges being rolled inwards and overlapped by its opposite edge; these are not all turned in one direction, two being dextrorsely, and the other three coiled up alternately in a sinistrorse order. This mode of restivation is certainly extremely unusual and peculiar, approaching that observed in the Goode- noviacece, on which on a former occasion (Lond. vii, p. 59) I have made some observa- tions. There exists between them this difference, that here each lobe is longitudinally and su
