Geranium.'] xxxii. geram acf.i: (olivrk). 291 



l-seeded, usunlly separating from the beak-like axis, witli rcvolute elastic 

 tails. Seeds with little or no albumen. — Herbs, occasionallv shrubby or 

 caespitose. Leaves opposite or alternate, stipulate, palmately divided in the 

 following species. Peduncles 1-2-flowered, axillary. 



A rather large genus, widely dispersed in temperate countries. The tropical .\frican 

 species which are known to me appear peculiar to this continent and its islands. 

 Carpels smooth, pilose. Flowerstalks usually exceeding the leaves. 



Pilose or pubescent. Teeth of the leaves broadly pointed, mucronu- 



late or rather obtuse 1. G.simmsi'. 



Retrorsely aculeolate. Teeth of leaves acute 2. G. acuholalum. 



Carpels deeply pitted and tubercled. Flowerstalks very short ... 3. G.fatoaum. 



1. G. simense^ Hochst. in Rich. Ft. Abyss, i. 116. A diffusely-branched 

 procumbent or ascending herb. Stem pilose or pubescent with dcflexed 

 hairs at least above, often glabrescent below. Leaves 5 -fid or sub-5 -partite, 

 more or less deeply incised with broadly pointed mucronulate or rather ob- 

 tuse teeth, pilose-pubescent at least beneath. Petioles various, pilose or pu- 

 bescent. Stipules ovate-elliptical, obtuse or rather acute, subscarious, gla- 

 brescent. Peduncles and pedicels exceedino; the leaves. Sepals oblonp;-lan- 

 ceolate, rather obtuse, apiculate, pilose, eglandular, shorter than the entire 

 petals, which are obsoletely or slightly ciliate below. Carpels setose-pilose 

 above, smooth. — G. compar, R. Br. in Salt, Abyss. App. 65. G. laiiftipu- 

 latum, Hochst. ; Rich. 1. c. G. frigidum, Hochst. in PI. Schimp. Abyss,

Var. repens. Stem very slender, rooting, patent-pilose. Peduncles elongate. — G. emir- 

 uense, Hils. et Boj. lus. iu Herb. Kew; Dr. Hooker in Journ. Linn. Soc. vii. 185. 



Upper Guinea. Fernando Po, 8-9000 ft., Mami ! 



Var. gJabrior. Stem glabrous or nearly so, attaining, probably with support, 4-8 ft. 

 Camaroons mountain, 7000 ft., Mann ! 



The variety which I have distinguished as repens agrees well with the Madagascar plant 

 of Hilsenberg and Bojer, as shown by Dr. Hooker (Linn. Journ. 6), but except in respect 

 of habit and indumentum, I see no character to distinguish either it or the glabrous form of 

 the Camaroons from G. simense. 



2. G. aculeolatum, Olii\ Perennial. Branches decumbent nn<l root- 

 ing below or ascending, retrorsely aculeolate. Leaves 5-partite ; srgmeuts 

 deeply incised with acute teeth, sparsely setose-pilose beneath, glabrescent or 

 with "^scattered pubescence above, H-H i"- <l'='"^- ^'" pi'o^^'^'^lv often larger. 

 Peduncles with scattered recurved setae, 2-floweie(l, exceeding the leaves ; 

 pedicels and sepals glandular-pilose. Sepals oblong-lanceolate with a raliier 

 long apicidus. Petals entire, ciliate at the base, about twice as long as the 

 sepals. Carpels smooth, shortly pilose. Seeds very minutely punctate. 



Nile Iiand. Abyssinia, Schimper ! Roth ! 



Roth says the flowers are white. They are probably also purple. 



3. G. favosum, Hochst. ; JRich. Fl. Mj/si. i. 117. Annual, ascending, 

 more or less branched, from 13 or 4 ft. in height. Branehes glandular- 

 pilose above, glabrescent below. Leaves 5-partite or deeply 5-fid ; segmcnU
