nifled. Fig. 5, a stamen, more magnified. Fig. 6, the sepals, thrown back to show the inner scales, 

 the lohes of the disk and the ovaries : much magnified. Fig. 7, the two divergent foUicles, a por- 

 tion of one being removed, showing the placenta and seeds. Fig. 8, a seed in its convoluted form. 

 Fig. 9, the same, flattened, showing on its ventral face the hilar point of attachment ; the same is 

 also shown on its back and edge. Fig. 10, a transverse section of a seed, to show its convolution 

 round the placenta : all somewhat magnified. 



Plate XIV. 



A. Elytropus pubescens, a portion of a plant. Fig. 1, a flower just opening, natural size. Fig. 2, the 



corolla, cut open to show its dextrorse convolution and the position of the stamens, magnified. 

 Fig. 3, a stamen shown before and behiud, more magnified. Fig. 4, the sepals, thrown back to show 

 the two scales at the base of each, the 5-lobed disk, the ovaries, style, clavuncle, and stigmata, much 

 magnified. Fig. 5, the two pilose follicles. Fig. 6, a transverse section of the same, to show the manner 

 of placentation : more magnified. Fig. 7, one of many seeds attached to the placenta by a central 

 hHum, natural size. Fig. 8, a seed, shown in three positions, magnified. 



B. Eriadenia obovata, a portion of a plant in flower and fruit. Fig. 1, a flower in bud. Fig. 2, the 



coroUa cut open, to show the peculiar form of the segments, which are introflexed in sestivation, the 

 scales in the mouth of the tube, and the position of the stamens : natural size. Fig. 3, a stamen, in 

 different positions, magnified. Fig. 4, the calyx, with the sepals thrown back, showing each with 

 three acute basal scales, the disk, style, clavuncle, and stigmata, somewhat magnified. Fig. 5, the same 

 parts, shown separately. Fig. 6, one of the lobes of the disk, shown outside : magnified. Fig. 7, the 

 ovaries, style, and clavuncle. Fig. 8, the two subtorose follicles. Fig. 9, a seed : wa^wraZ si^'e. Fig. 10, 

 the same, magnified, showing it to be linear oblong, compressed, rostrate, covered all over with 

 long rigid hairs spreading in all directions. 



Plate XV. 



A. Rhabdadenia paludosa, a portion of a plant in flower. Fig. 1, the corolla cut open, showing the 



dextrorse convolution of its short segments, and the position of its stamens. Fig. 2, the calyx. 

 Fig. 3, the same, with the sepals thrown back to show the minute basal scales, the disk, ovaries, 

 style, and clavuncle : all natural size. Fig. 4, the same parts, somewhat magnified. Fig. 5, the rest 

 of the style, clavuncle, and hairy stigmata, also magnified. Fig. 6, a stamen, much magnified. 

 Fig. 7, the two erect foUicles. Fig. 8, one of the seeds, narrowly rostrate at the apex, where it is 

 feathered with numerous long silky bairs, which must not be mistaken for a coma ; the longitudinal 

 raphe, proceeding from a central hilum, terminates below the rostrum in a short funicle. Fig. 9, the 

 same with the hairs removed, to show the form of the rostrum. Fig. 10, the nucleus, consisting of a 

 heterotropous embryo imbedded in albumen. Fig. 11, the embryo extracted, with a terete superior 

 radicle much longer than the two short oblong cotyledons : all natural size. 



B. Chariomma surrecta, portion of a plant in flower. Fig. 1, the corolla in bud. Fig. 2, the same cut 



open, to show the sinistrorse convolution of its large very acute segments and the position of its 

 stamens furnished with long spiraUy-twisted apical appendages. Fig. 3, the calyx on its pedicel. 

 Fig. 4, the same with the sepals thrown back, to show the absence of inner scales, the 5-lobed disk, 

 the style, and clavuncle : all natural size. Fig. 5, the same parts, magnified. Fig. 6, portion of the 

 style, clavuncle, and stigmata, more magnified. Fig. 7, a stamen with its very long torsile apical 

 appendage, three times magnified.
