本文描述了猴花属一新种--苏氏猴花（Mimulus sookensis）。该物种分布于温哥华岛南部、不列颠哥伦比亚省的海湾群岛、华盛顿州的圣胡安群岛、俄勒冈州的威拉米特和乌姆普夸河谷，并曾在加州的门多西诺县的一个地点被采集。Sookensis是一个四倍体的物种（n = 28），来自占主导地位的异交Mimulus guttatus DC。（a = 14）和主要自花授粉的微小拟态拟态（Mimulus minims）格林（n = 14）。Mimulus sookensis与小花M. nasutus，但在染色体数目、高度和花冠筒比M.鼻骨。常见于潮湿的山坡、渗水处、路堑和路边沟渠，常与M. guttatus，但很少与M.鼻骨。
A new species of monkeyflower, Mimulus sookensis, is described. This species is found throughout the southern portion of Vancouver Island, the Gulf Islands of British Columbia, the San Juan Islands of Washington state, the Willamette and Umpqua River Valleys in Oregon, and has been collected at one location in Mendocino County, California. Mimulus sookensis is a tetraploid species (n = 28) derived from the predominately outcrossing Mimulus guttatus DC. (a = 14) and the predominately self-pollinating Mimulus minims Greene (n = 14). Mimulus sookensis is similar phenotypically to the small-flowered M. nasutus, but differs in chromosome number, height, and by a slightly more narrowed corolla tube than that of M. nasutus. It is commonly found on wet hillsides, seeps, cutbanks, and in roadside ditches, often co-occuring with M. guttatus but infrequently with M. nasutus.
