MIMBRES. i'hilop.sis s,ili,j}ia. 



MIMOSA (Greek, a mimi<\ alluding to the fact tbat 

 tht^ leaves of some species are sensitive). Legumuidsoi. 

 What the florists know as Mimosas are Acacias (chiefly 

 A. <i nil a fa). Mimosa has stamens 10 or less (once or 

 twice as numy as the petals); Acacia has numerous 

 stamens. Of Miinosas there are between 200 and 300 

 species of tropical regions, chiefly of tropical America. 

 Trees, shrubs or herbs (sometimes woody climbers), 

 with bipinnate often sensitive Ivs. (sometimes the Ivs. 

 reduced to phyilodia): fls. usually with 4 or 5 united 

 petals, and a very minute or obsolete calyx: pollen 

 granular: pod flat, obiotig or linear, breaking up into 

 Lseeded joints when ripe. 



A. Herbaceous phints. 



ptidica, Linn. Sensitive Plant. Humble Plant. 

 Fig. 140:i. (Jiilt. as an annual, but probably perennial in 

 the tropics, erect, branching, hairy and spiny: Ivs. loug- 

 petioled, with 2 or 4 sub-digitate pinnate linear-oblong- 

 Ifts. : tis. many, in globular-oblong heads on elongatiiii,'- 

 axillary peduncles, [)urplish : pods comprising 3 or 4 spiny 

 joints. Brazil, but widely naturalized in warm countries. 

 — Easily grown from seeds, which are sold by seedsmen. 

 The plant grows readily in any place in which garden 

 beans will thrive. It is grown for its sensitive foliage. 

 The movements are usually quickest in young plants. 

 When the Ivs. are tonched, the petiole falls and the leaf- 

 lets close. Neither tin- mechanism nor the utility of these 

 movements is well understood. M. scvsiDva, Linn., 

 is a distinct plant ( B.R. I :25). It is a half -climbing per- 

 ennial with 2 unequally pinnate Ifts., not so sensitive as 

 M. pudlra. The word pitdira is Latin for modest or 

 r>'tiriii</.
