R. ligerinus Genev. ! Mem. Soc. Acad. Angers, viii. (1860). 



Stem j)rostrate, round, glaucous-green, slender, with very 

 small scattered declining or deflexed prickles from slightly 

 enlarged bases; hairs, setae and aciculi very few or wanting. 

 Leaves ternate. Leaflets thin, flexible, flat, dull green, and 

 pilose above, rather glaucous, and with hairs on the veins 

 beneath, lobate-serrate ; basal subsessile, ovate-acuminate or 

 broadly lanceolate, with a large lobe on the lower side; 

 terminal long-stalked, rhomboidal-ovate, acuminate ; petioles 

 (which are furrowed above) and midribs with few very small 

 prickles beneath ; stipules linear-lanceolate. 



Flowering shoots from fuscous scales, resembling the 

 stem, Piickles very few and very small. Leaves ternate. 

 Leaflets rhomboidal-ovate, lobate-serrate, resembling those 

 of the stem. Panicle small, leafy, with rather few short 

 declining prickles, and a few setae and aciculi; flowers 

 in terminal axillary corymbs. Pedanrhs felted, setose, 

 prickly. Sepals ovate, acuminate, with a rather long 

 point, greenish with a narrow white margin, felted, slightly 

 setose, clasping the fruit. Petals white, obovate, with two 

 or three notches at the end, clawed. Filaments white. An- 

 thers cream-coloured. Styles greenish. Sometimes the 

 stamens and styles are yellowish. Fruit of few large black 

 glaucous drupels. 



The panicle of this plant is often nearly simple, and when 

 otherwise the branches are rarely more than once divided; 

 they are very variable in length, and are sometimes exceed- 

 ingly long.
