HITHEKTO UNDESCRIBED PLANTS PROM ARNHEIm's LAND. 75 



very short, but dilated downward. Cotyledons pale ; radicle very 

 short, slightly curved, partly enclosed. Strophiola ellipsoid in 

 outline, turgid. Nearest allied to D. debilis. 



Some difficulty has arisen in assigning to this plant its generic 

 position ; it accords in every respect with Dunbaria, except 

 development of a large and turgescent strophiole, which is quite 

 that of Atylosia and so the septation, but the fruit has not the 

 traverse impressions of that genus and of Cajanus. From the 

 normal species of Rhynchosia our plant recedes merely in having 

 a fruit containing more than two seeds with cellular somewhat 

 membranous disepiments between them, although the strophiole 

 is often very minute; but as in many other genera of Papilionacese, 

 for instance Indigqfera and Tephrosia, fruits occur with one and 

 with several seeds, it might "pari passu " be advisable, to reduce 

 Caja?ius, Atylosia and Dunbaria as sections of Rhynchosia also. 

 The inflorescence is that of Rhynchosia uni flora and Dunbaria 

 debilis, as hardly needs to be noted. 



Clerodendron Holtzei. 



Pendant or prostrate or diffuse, much beset with short spread- 

 ing hairlets ; leaves comparatively small, almost sessile, from 

 cordate- to rhomboid-orbicular, above nearly glabrous ; peduncles 

 terminal and from the axils of the upper leaves, bearing cymousely 

 from three to several flowers ; bracteoles narrow, very short ;. 

 flowers rather small ; calyx cleft to near the middle, finally some- 

 what enlarging, but without succulence, its lobes acute ; corolla 

 pure white, outside beset with minute hairlets, its tube nearly 

 doubly as long as the calyx, at the orifice bearing soft hairlets, its 

 lobes from ovate to orbicular, about half as long as the tube ; 

 stamens hardly extending beyond the corolla-lobes ; anthers 

 ellipsoid-sagittate ; style glabrus, almost totally enclosed ; fruit 

 shorter than the calyx; pericarp thin, somewhat succulent; endo- 

 carp thinly osseous, often only one of the nutlets perfect. In 

 clefts of rocks, the comparatively long carnulent root deeply 

 penetrating. Stems seemingly but slightly woody, often only a 

 foot long even when flowering, slender. Leaves mostly measuring 

 1 — 1^ inches, exceptionally somewhat indented, never pointed. 

 Calyx occasionally 6 cleft. Corolla measuring -|- - § inch in 

 length. Nutlets \ — \ inch long, when solitary verging into a 

 globular form. Testa pale. Cotyledons white, turgid ; radicle 

 very short. 



This species is as regards its flowers not unlike C. tomentosum, 

 but the stamens are shorter, and the leaves as well as the stature 

 and the fruit are widely different ; in size of the leaves it comes 

 near C. phlomoides.
