Mimulus gemmiparus
''Mimulus gemmiparus'' is a rare species of flowering plant in the family Phrymaceae, known by the common name Rocky Mountain monkeyflower. It is endemic to Colorado in the United States, where there are eight known occurrences.〔(''Mimulus gemmiparus''. ) The Nature Conservancy. Retrieved 11-04-2011.〕
This annual herb grows about tall. Some of the leaves have propagules on their petioles called gemmae. When a leaf falls off the plant the gemma can generate a new plant; this is the mode of reproduction for this species, as flowers are rarely produced and they are sterile.〔Moody, A., et al. (1999). (Developmental analysis of the evolutionary origin of vegetative propagules in ''Mimulus gemmiparus'' (Scrophulariaceae). ) ''Am J Bot'' 86 1512-22. Retrieved 11-04-2011.〕 The gemmae are probably dispersed on water. The plants occur in colonies of mother and daughter plants.〔 When they do occur, the flowers are yellow with variable patterns of red spots and measure about half a centimeter long. While the flowers are rare in nature, the plants may produce many flowers when propagated in the greenhouse.〔Beatty, B.L., W.F. Jennings, and R.C. Rawlinson (2003, November 21). (''Mimulus gemmiparus'' W.A. Weber (Rocky Mountain monkeyflower): A technical conservation assessment. ) (). USDA Forest Service, Rocky Mountain Region. Retrieved 11-04-2011.〕
This plant grows in subalpine climates in moist areas such as seeps in granite outcrops and overhangs and forest habitat near springs. It can often be found alongside other ''Mimulus'' species,〔 such as ''Mimulus floribundus'', ''M. guttatus'', and ''M. rubellus''. The forests are dominated by spruce, fir, and aspen and other plants in the habitat may include ''Jamesia americana'' (fivepetal cliffbush), ''Dodecatheon'' spp. (shootingstar), ''Aquilegia saximontana'' (Rocky Mountain blue columbine), ''Epilobium'' spp. (fireweed), ''Salix'' spp. (willow), ''Campanula rotundifolia'' (bluebell bellflower), ''Artemisia ludoviciana'' (white sagebrush), ''Packera plattensis'' (prairie groundsel), ''Erigeron subtrinervis'' (threenerve fleabane), ''Rhodiola integrifolia'' (ledge stonecrop), ''Oreochrysum parryi'' (Parry’s goldenrod), ''Brickellia microphylla'' (littleleaf brickellbush), ''Amelanchier utahensis'' (Utah serviceberry), and ''Montia chamissoi'' (water minerslettuce).〔 Threats to this species include recreational activities such as hiking and horseback riding.〔
