base rounded, unequally serrate, on petiolules usually of 1 line or less, 

 thinly hairy above, paler and shortly hoary-tomentose or shortly thinly 

 and softly pilose especially on the'nervures beneath. Panicles ter- 

 minal, pilose-tomentose, the flowers usually clustered or compact. 

 Calyx-lobes linear-lanceolate acuminate. Petals or scarcely exceed- 

 ing- the carpels which are glabrous, at length dry and sculptured or 

 thinly succulent. — R. exsuccus, Steud. ; Rich. PI. Abyss, i. 256.

Originally described from Mascarene specimens. 



3. R. rigidus, Smith?; DC. Prod: ii. 556. Loosely branching shrub, 

 attaining 7-8 ft., branches closely appressed hoary-tomentose, with a 

 few microscopic glandular hairs towards the panicle j prickles decurved. 

 Leaves 3-fbliolate on the flowering branches, glabrous above, paler 

 hoary-tomentose beneath, leaflets more or less ovate ovate-elliptical 

 or -rotundate, acute, unequally broadly serrate, petiolules of lateral 

 leaflets to 1 line. Panicles lax, more or less leafy. Calyx-lobes ovate- 

 lanceolate apiculate. Petals shorter than calyx. Carpels thinly oilose, 

 glabrescent, at length thinly succulent, " black-purple."

Differing from the above in little but the stem more loosely tomentose or pilose- 

 tomentose, and more aculeate, inflorescence, are specimens collected by Messrs. Chap- 

 man and Baines in South-West Africa, lat. 23° ; no precise locality on the label. I have 

 not seen barren shoots nor 5-foliolate pinnate leaves on either of the above plants. 



4. R. Steudneri, Schweinf. in Verh. Zool. Bot. Gesell. Wien. 1868, 669. 

 Stem angular, greyish-tomentose, and with crowded patent glandu- 

 lar hairs; prickles straightly reflexed, towards the apex tomentose. 

 Leaves 3-foliolate ; leaflets oval acuminate, rounded or obscurely cor- 

 date at base, doubly serrate, glabrate above, densely whitish-tomentose 

 beneath. Panicle terminal much-branched, branches glandular-tomen- 

 tose ; pedicels slender, aculeate, much exceeding the tomentose eglan- 

 dular calyx. Petals obovate-oblong twice as long as the calyx, pur- 

 plish. 



Nile Land. Abyssinia, Steudner. 



Description taken from Dr. Schweinfurth's Memoir. 



M. Richard (Fl. Abyss, i. 256-57) describes two Rubi gathered in Abyssinia by 

 Messrs. Q.-Dillon and Petit, of which I have not seen specimens. They are : R. Peti- 

 tianus (? also R. compar, R. Br. in Salt, App. 64). Stem and petioles tomentose. Leaflets 

 ternate, inciso-serrate concolorous, closely pubescent (not tomentose). Sepals oval, 

 abruptly acuminate. Petals and fruit undescribed : and R. Quartinianus. Stem and 

 petioles pale-tomentose. Leaves pinnate, leaflets usually 5, whitish-tomentcse beneath. 

 Flowers solitary, or two or three on a common peduncle in the upper axils. Sepals oval- 

 oblong acuminate. Petals 0. I take this to be probably a form of R. apetalus, Poir. 

 Schimper's recent (1863-8) collections, include also two or three Rubi not identifiable 

 with those in the Kew Herbarium, but no good purpose would be served by describing 

 ihem from the materials as yet to hand.
