244 S7. R. i'OLiosus. 



acuminate, unequal and sometimes subcordate at tlie base ; 

 terminal roundly cordate acuminate ; petioles (which are 

 slightly furrowed above) and midribs with rather many 

 slender, declining or deflexed prickles beneath; stipules 

 linear. 



Flowering shoot with few small slender long-based de- 

 clining prickles, aciculate, setose, hairy. Leaves ternate. 

 Leaflets coarsely doubly serrate, slightly pilose dark green 

 and opaque above, rather paler and hairy on the veins be- 

 neath ; basal shortly stalked, unequally ovate, acute ; ter- 

 minal broadly ovate-acuminate. Panicle with many long 

 slender long-based declining prickles, and many very un- 

 equal aciculi and setae, very long, narrow, leafy to the top ; 

 uppermost floral leaves simple ; lowest branches racemose ; 

 others corymbose, about 3 -flowered, with peduncles of nearly 

 equal length j branches and peduncles very hairy setose and 

 aciculate ; rachis slightly wavy, less densely clothed than 

 the peduncles. Sepals ovate-attenuate with a slender point, 

 very hairy, bearing many long setae and aciculi, loosely re- 

 flexed from the fruit. Petals obovate, clawed, distant, white, 

 slightly crenate at the end. Filaments white. Anthers 

 yellowish. Styles greenish. PriTnordial fruit-stalk rather 

 short. Nut half-ovate ; inner edge straight. 



Mr Bloxam remarked in 1847 that "this plant seems to 

 accord exactly with the figure and description in the Ruhi 

 Germanici.^^ But there are some slight differences between 

 our specimen and that described and figured in that work : 

 chiefly that the terminal leaflet of our plant is much 

 more markedly cordate below ; the panicle-branches are 

 more patent, and the calyx is differently clothed. In all 

 these respects it agrees much better with the R. exsecatus 

 (Midi.), with which indeed I think it is identical. Weihe 

 and Nees remark that the sepals of their plant are " prseter 

 tomentum neque glanduli neque alio armorum genere in-
