1018 MIMULUS 



MtMULTTS (Latin, a little miniir. from the grinning 

 fls.). Scrophnlaridceie. This genus iucludes the Monkey 

 Flower, it/. Iiiteus, and the Music Plant, M. moschatiis. 

 Monkey Flowers are something like snapdragons, though 

 they do not have a closed throat. They are 2-lipped fls., 

 with 2 upper and ',i lower lobes, which arc all rounded 

 and usually irregularly splashed and duttcd with brown 

 on a yellow ground. Though peremii;il. tlicy are com- 

 monly treated as annuals and are coiisidrrabiy used for 

 pot culture in winter, as well as for sunjmer bloom out- 

 doors. The Musk Plant is grown for its scented foliage 

 and pale yellow fls. It is sometimes used in hanging 

 baskets, but the foliage is so sticky that it gathers a 

 great deal of dust. 



Mimulus is a genus of about 40 species, mostly Ameri- 

 can: herbs, decumbent or erect, glabrous or pilose and 

 clammy, rarely shrubby: Ivs. opposite, entire or toothed: 

 fls. axillary, solitary or becoming racemose by the reduc- 

 tion of the upper Ivs. ; calyx 5-augled, with 5 short or 

 long teeth; corolla ttibe cylindrical, sometimes swelled 

 at the throat; stamens 4, didj^namous: capsule oblong 

 or linear, loculicidally dehiscent. 



The kinds described below are all perennial at least 

 by undergrotmd parts, and most of them are natives of 

 wet and shady places in northwestern America. Latest 

 monograph by A. Gray in Syn. Flo. N. Amer., Vol. II, 

 part 1, pp. 273, 442. They mostly grow 2-4 ft. high and 

 bloom all summer. Mimulus Ciilitornica is advertised. 

 Diplaeus is generally referred to Mimulus. •\y, ji. 



The sight of Monkey Flowers always carries the writer 

 back to boyhood days. A certain window on his way to 

 school was brightened every spring by a fine display of 

 Monkey Flowers and Musk. Though these two species 

 were thus happily associated, it is doubtful whether the 

 owner knew of their kinship. There is nothing diflicult 

 in the culture of Mimulus. Some of the finest plants 

 have been self-sown on a rubbish heap. Abundance of 

 water is essential. The seed has great vitality, and will 

 germinate for many years in the place where once seeds 

 have fallen. They are not hardy. 



M. luteus, with its varieties and hybrids, particularly 

 var. maculosuSfis the best known. There are double and 

 hose-in-hose varieties, but the single forms are the hand- 

 somest. It often self -sows in moist gardens. M.cardi- 

 rialis, a handsome Californian perennial, is occasionally 

 hardy, but does best treated as an annual. M. ghttinoaa 

 is a pretty shrubby species, with coppery fls., once a 

 common greenhouse plant, but rare enough now to be 

 almost a novelty. t. d. Hatfield.
