The ovule also is descending; and, as MUekeiia repens. in Frismatomeris and for the same reason, the embryonic radicle is inferior. The flowers are soUtary or ge- minate. They have the same organization as in MitcheUa (fig. 294), gene- rally referred to another series and inhabit, one Japan, the other North America. They are peren- nial climbing herbs and perhaps only a section of Damnacanthus.

The sti- pules are membranous, not spuious,in the tr-aeMitcheUa, and the axillary or terminal geminate flowers have their ovaries united in a common receptacle, instead of being independent like those of Damnacanthus ; a character observed in various honeysuckles.' Gremaspora (fig. 296), with Alberta, has been ranged in a separate tribe (Albertew) of Rubiacece, with solitary descending ovule, the corolla of which is contorted instead of being valvate. Otherwise, their resemblance to Ganthmm- is very close. The stamens are inserted in the throat of the corolla, and the fleshy fruit encloses one or two descending and albuminous seeds. In the true Gremaspora, the flowers are generally pentamerous; the style is not divided, and the horny perisperm is continuous. In those named Polyspharia, the flower is-in four or flve parts ; the style is ordinarily divided into. Fig. 294. Long. sect, of two-flowered inflorescence ()). ' In DicMl'Mthe, of Ceylon and Borneo, there are, not two but, a greater number of flowejfs forming a false capitule. The corolla is curved and subbilobed. Sahmannia and Phialanthus, American shrubs, have also many-flowered cymes; but they are axillary. The corolla is valvate or slightly imbricate. The anthers of the former are basifixed, of the latter, dorsifixed. All have a dascending ovule with dorsal Please note that these images are extracted from scan
