unequally crenate-serrate. Siliquas erect, very narrow, at length sometimes 

 nearly glabrous. 



Nile Ijand. Abyssinia, Petit .' Schimper ! 

 Ijower Guinea. Angola, Goluugo Alto, Dr. Welicit.tch ! 



Very nearly allied to an Indian plant, regarded as a form of C. hirsitta, by Dr. Hooker. 

 Dr. ^Vel\vitsch found his plant always apctalous and with tctrandrous flowers. 



4. C. hirsuta, Linn. ; DC. Syst. Veg. ii. 259. A small, erect or ascend- 

 ing annual herb, often much branched or tufted at the base. Leaves pinnate ; 

 segments rounded, ovate or obovate, broadly toothed, the upper narrower, 

 glabrous or with a few scattered hairs. Stamens often fewer than 0. Siiiquas 

 erect, on short pedicels. — C. simensis, Hochst. in PI. Schimp. Abyss. 



Upper Guinea. Fernando Po, 7500-8500 ft., and Camaroons mountain, 8000- 

 10,000 ft., Mami! 



Nile Land. Abyssinia, near Demerki, Schimper ! 

 Common iu nearly all temperate countries. 



6. MORETTIA, DC; Benth. et Hook. f. Gen. PL i. 70. 



Sepals erect, equal. Petals narrow or linear. Siliqua nearly terete, erect, 

 recurved above, on a short thick pedicel ; valves rigid, nerved or subnirinate, 

 somewhat septate within, tardy in dehiscing ; style short ; stigma 2-lobcd. 

 Seeds compressed in a single row. Radicle accumbent. — Branched, leafy, 

 rather rigid herbs, w^ith entire or dentate, stellate-hispid or hoary, sessile or 

 subsessile leaves. Racemes leafy. 



A small desert genus of N. Africa and Arabia. 



1. M. Philaana, DC. Syst. Veg. ii. 427. A stiff, erect, hispid herb, 

 6-12 in. high, with divaricate leafy branches. Leaves lanceolate, hnear-lan- 

 ceolate or oblanceolate, rather acute or obtuse, dentate or entire, .^-l in. long, 

 hoary and hispid on both sides, with rough stellate hairs. Flowers in the 

 axils of the upper leaves or extra-axillary. — Del. Fl. yEgypt. t. 33. f. 3. 



Nile Land. Nubia, Nectoux (DC. I. c), Br. Bromfield! 



Desert of Belama, Nubia, Speke and Grant ! An imperfect, leafless specimen, probably 

 of this species. Tufts of it, " rolled into spheres, blow over the saudy desert." Grows also 

 in Arabia and N. Africa. 



It is probable that the following genera allied to Morettia, but differing in their appcn- 

 daged siliquas, may be found in the deserts north of the equator : — 



Notoceras {N. canariense, Br.), occurring iu the Canaries, N. Africa, and Arabia. It 

 may be distinguished by its linear leaves and short siliquas, terminating iu a pair of short 

 horn-like processes. 



Lonchophora, a N. African genus, has subsessile siliquas, bearing a horn-like appendage 

 at each side of the base. 



Anastalica {A. hierochuntica^ Linn., the " Rose of Jericho "), of Arabia, Syria, and 

 Algeria. Fruits very short, bearing a round concave auricle on each side of the broad apex, 

 from the centre of which projects the persistent subulate style. 



7. FARSETIA, Desv. ; Benth. et Hook. f. Gen. PI. i. 72. 



Sepals erect ; the lateral slightly saccate. Petals with long claws. Siliqua 

 various in outline, from linear to orbicular, flat-compressed or turgid, with 

 plane or convex, nerved or nerveless valves. Stigma 2-fid or capitate with a
