formed each of a uuilocular ovary lodged in the cupular receptacle, 

 so that the base is applied outwards to the internal wall of the cup, 

 and the summit directed ohliquelj^ inwords. From this point sprin.^s 

 the st3de, rising vertically, witliout adhering to the other styles, which 

 have not the same length in all the carpels, each terminating in a 

 small stigmatiferous head. The fruit is formed of from five to ten 

 capsules which remain incrusted in the concavity of the receptacle. 

 On the outside persist the calyx and epicalyx developing more 

 or less unequal spines. In each capsule, dehiscing by an upper 

 cleft, is seen an oblique seed the coats covering a fleshy embryo, 

 with plano-convex cotyledons and cylindrical radicle. The only 

 liuown species of this genus ' is an annual herb growing in the 

 sandy regions of North and East Africa. The stems, finally 

 ligneous at the base, covered, like the rest of the plant, with an 

 abundant woolly down, separate into branches which sjn-ead upon 

 the ground, and arc covered with alternate pctiolate j^innatisect or 

 lobate leaves, accompanied by one or two small lateral stipules (?). 

 The flowers are axillary or nearly so, solitary and pedunculate. 

 When the seeds are ripe, they germinate in the induviate fruit 

 which they attach to the ground, it being often found at the 

 base of a plant bearing the fruit of the following generation. 



On looking at the very singular habit and dull corolla of Neunida, 

 we can understand its having been generally placed in a family very 

 distant fr'om the present.^ But when we observe an inseparable genus 

 Gn'eluiii,^ only distinguished by its calyx without epicalyx, and its 

 much developed contorted petals, in every way resembling those of 

 Gci'dnmm, we cannot but admit that the Nciiradcœ are Bichcrstcinîeœ 

 in which the carpels are inserted in a concave floral axis instead of 

 on a more or less prominent receptacle, i. e., of the perigynous 

 Geraniums. The three known species of Griclum ^ are natives of the 

 sandy and salt plains of South Africa.
