MIMULUS (Latin, a liUh mimic, from the grinning 

 fl."!.;, Srriii>hidariacex. Mo.stly herbs (annual or peren- 

 nial; with interesting irregular flowers in many colors, 

 some of them border subjects and others flower-garden 

 plants, 



Lfjw plants (sometimes shrubby), decumbent, ascend- 

 ing or erect, glabrous or yiilose and often clanniiy: Ivs, 

 opposite, entire or toothed: fls, axillary, .solitary or 

 becoming racemose by th(! red\iction of the upper Ivs.; 

 calyx .">-angle<l, with 5 short or long teeth; corolla-tube 

 fylindrical, Sfjmetimes swollen at the throat; stamens 4, 

 didjTiamous: caps, oblong or linear, loculifidally deliis- 

 c<;nt, — SjKJcies 7)robably IK) or 70, if Dipkaciis, Kunarius 

 and Mimulastrum are included, mostly in extra- 



Trop, Amer,, but some in Asia, Austral, and Afr. The 

 genus is specially rich in W, N, Amer, This genus 

 includes the nionkev-llower, M. Iiiliii.i, and tlu^ musk- 

 plant, M. moscliiiliis. Monkey-flowers are somelhing 

 like snaixlragoMs, altlumgli they do not have a do.sed 

 throat. They are 2-lipped Hs., with 2 npi)er and 3 lower 

 lobes, which are all rounded and u.sually irregularly 

 splashed .and dottcil with brown on a yeUow ground. 

 Though pereimial, (hey are coiniuonly treated as 

 annuals and are considerably u.sed for pot cult, in winter, 

 as well as for sunnuer bloom outdoors. The mu.sk- 

 ])lant is grown for its scented foliag<' and pale yellow fls. 

 It is sometimes used in hanging-baskets, but the foliage 

 is so sticky that it gathers too nuich dust. The kinds 

 tlescribinl below are all perennial at least by under- 

 ground parts (except M. hrcrijict), and most of them 

 arenativesof wet and shady places in N. W. Amer. They 

 mostly grow 1-3 ft. high and bloom all summer. Dij)- 

 lacus is here include<i in Miniulus. 



Minuilus plants (M. lutciis) can be increa.sed by sow- 

 ing seed from .lanuary to April in pans of light sandy 

 soil. They liT<(! a mixture of loam, leaf-mold and sand 

 in equal parts. They may be ke])t in a temperature of 

 ()0° until they show signs of coming up, when they 

 should be placed in a house that stands at about .50° 

 during the night. As soon as the seedlings can be hand- 

 led, they should be potted off into small pots and 

 grown aiong in .as cool a house iis possible. The early- 

 ,so\vn jjlants (^an be planted out in May in a cool 

 shady situation, where, if they can have enough water 

 to keep the roots moist, they will bloom fairly well. 

 Those that are sown late can be grown on by shifting 

 into 2-, 3-, 4- and 5 -inch pots, using a compost of 

 fibrous loam three parts, well-decayed cow-manure 

 one part, and enough sand to keep the compost open. 

 In the summer these may be grown outside in frames 

 covered by lath shading. Late in autumn they may 

 be brought into a eoolhouso with 4,5° to 50° night 

 temperature. Give them a place near the glass, and 

 with care as to watering and ventilating they will 

 bloom satisfactorily. They can also be increa.sed from 

 cuttings taken in the early spring. — M. moschatus can 

 be grown from seed and cuttings. They may be 

 lilantod out in a partly shaded situation, where they 

 will grow all summer. In the autumn, lift some of 

 the clumiis ami pot them. These may be grown in a 

 coolhouse of about 4.5° at night. In the spring, when it 

 is desired to increase the stock, take pieces of the new 

 growth and place them around the sifie of a 3-inch pot, 

 using the compost mentioned above; by keeping moist 

 and shaded for a short time, they will soon root into 

 the mixture and be ready to grow on. These may be 

 shifted into 4-inch pots and soon will make fine little 

 plants by their rapidly creeping growth. (J. J. M.
