HEINRICH HASSELBRING. 

 MIMBEES. Chilopsis saligna. 



MIMOSA (Greek, a mimic, alluding to the fact that 

 the leaves of some species are sensitive). Leguminbsce. 

 What the florists know as Mimosas are Acacias (chiefly 

 A. armata). Mimosa has stamens 10 or less (once or 

 twice as many as the petals); Acacia has numerous 

 stamens. Of Mimosas 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 phyllodia) : fls. usually with 4 or 5 united 

 petals, and a very minute or obsolete calyx: pollen 

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

 1-seeded joints when ripe. 



A. Herbaceous plants. 



pudica, Linn. SENSITIVE PLANT. HUMBLE PLANT. 

 Fig. 1403. Cult, as an annual, but probably perennial in 

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

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

 Ifts. : fls. many, in globular-oblong heads on elongating 

 axillary peduncles, purplish : 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 touched, the petiole falls and the leaf- 

 lets close. Neither the mechanism nor the utility of these 

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



> ct > 3~ K VS -J . ns - *-* _ m - " c | s ' is a distinct plant (B.R. 1:25). It is a half -climbing per-
