Genista tincloria (Dyer's Greenweed). 



edges is inserted the calyx. This is gamosepalous, with five divisions 

 of unequal size and depth. The three anterior are of nearly equal 

 length, approximated to form a 

 sort of lip, which is slightly 

 notched at the apex in the very 

 young bud. The two superior 

 or posterior are separated behind 

 by a cleft, so deep, that in cer- 

 tain species it extends to close 

 upon the edge of the receptacle- 

 The irregular papilionaceous 

 corolla has an oval standard, ob- 

 long wings, and a straight or 

 incurved oblong keel, whose 

 pieces are united for a variable 

 distance along the lower edge. 

 The angles of these petals are 

 often adnate for a short distance 

 to the staminal filaments. They 

 are monadelphous, united for a 

 o-ood distance into a closed tube 

 and only free near the apex. 

 The introrse two-celled anthers 

 dehisce longitudinally. The five 

 superposed to the petals are the 

 shorter and versatile, while the 

 alternating five are more elon- 

 gated and basifixed. The sessile 

 ovary is surmounted by an incurved style, inflexed or circinate 

 above, and ending in a globular, or more rarely oblique oblong, 

 stigmatiferous head. The ovules, two or three, or more frequently 

 indefinite in number, form two vertical rows on the posterior wall 

 of the ovary and are campylotropous and descending, with the 

 micropyle looking upwards and outwards. The fruit is an oblong- 

 linear or subglobular, indehiscent or bivalve pod ; the valves 

 are convex or turgid, rarely almost flat, and enclose a variable 

 number of exarillate seeds. The genus Broom or Genista comprises 

 shrubs or undershrubs from the temperate regions of Europe, 

 western Asia, and north Africa; some seventy species are
