vertical rows, v;hich always remain in the state of cellular tubercles. 

 Besides this tlie receptacle is convex ; the stamens are numerous, as 

 well as the cai*pels. All the other cliaracters are variable. Take, 

 for instance, the flower of J. alba Juss. (figs. 77, 78), or of any

of the many allied species f we see that the calyx is formed of five 

 petaloid sepals quincuncially imbricated in the bud, and that the 

 stamens are all fertile, each havinj]^ a basifixed two-celled anther 

 dehiscing by two nearly lateral clefts.^ The ovaries are surmounted 

 by a horn-shaped style of variable length, glabrous or hairy.' The 

 flowers are terminal, and accompanied by a leafy involucre placed on 

 tlie axis at a variable distance from the perianth. The other 

 species of this genus have their flowers exactly similar in all 

 fundamental points ; but the number of pieces in the perianth 

 is often increased, so that we sometimes find six, three outside, 

 and three interior to these, alternate with them, and tliinner

 qwlques attires Eenonculaa'es (Adansonia, i.

 (^Adansonia, iv. 52). It is only in exceptional 

 cases that we see two, three, tivc, or six cellular 

 prominences answering to abortive ovules.

 Candolle {I'rodr., i. 18, 21), in the genus 

 Anemone. 



' The cleft is often turned mtlier inwards than 

 outwards. This occurs in A. alha, pennxiflrunica 

 (Adansonia, iv. 1<>), uarcimijloru, m-murosa, iVc. 

 The contrary is little marked in A. Japunicu 

 (all/a), ranunculoidts, &c. The lilainenUi are 



usually unequal, the lower being usually the 

 shorter. We have also pointed out (Adansonia, 

 i, 337) the two glandular jjroji'ctions found on 

 each side of the top of the filament in a hirgo 

 number of species. 



■• Several authors following I)k C'axdoi.LK'9 

 example have made use of this character to esta- 

 blish sections of the genus. Thus, Pulsatilla

 surmounted by long bcardctl styles like thoau 

 of certain 8|)ecie8 of Clrmatis. The sections 

 Anemonanlhea, Anfm<niusf)ernius, and Omalo- 

 carpus (21) are, on the contrary, marked by 

 styles that project but little.
