Geranium.] xxxn. gf.raniace^: (olives). 291 



1-seeded, usually separating from the beak-like axis, with revolute elastic 

 tails. Seeds with little or no albumen. — Herbs, occasionally 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 African 

 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. simense. 



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



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



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

 procumbent or ascending herb. Stem pilose or pubescent with deflexed 

 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 exceeding the leaves. Sepals oblong-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, K. P>r. in Salt, Abyss. App. 65. G. latidipu- 

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

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

 nense, Hils. et Boj. ms. in Herb. Kew ; Dr. Hooker in Journ. Linn. Soc. vii. 185. 



Upper Guinea. Fernando Po, 8-9000 ft., Mann I 



Var. glabrior. 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 

 J* h* mt and indumentum, I see no character to distinguish either it or the glabrous form of 

 the Camaroons from G. ' 



simense. 



_ 2. G. aculeolatum, Oliv. Perennial. Branches decumbent and root- 

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

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

 with scattered pubescence above, \\-2\ in. diam. or probably often larger. 

 Peduncles with scattered recurved seta?, 2-flowered, exceeding the leaves ; 

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

 ] ong apiculus. Petals entire, ciliate at the base, about twice as long as the 

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

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



3. G. favosum, Hochst. ; Rich. Fl. Abyss, i. 117. Annual, ascending, 

 m °re or less branched, from 1-3 or 4 ft. in height. Branches glandular- 

 pdose above, glabrescent below. Leaves 5-partite or deeply 5-fid ; segments
