Marsupella 1a plants paroicous > Marsupella sp. nov. ined.
Synonym: None.
Special Status: None.
Recognition: This is a very small Marsupella of high elevation peaks and ridge tops in the western Cascades and high Cascades. It can be identified when sterile by the 3-6 oil bodies in midleaf cells. Most small species in the genus like M. brevissima have only two oil or occasionally three oil bodies per cell (Schuster 1974; Paton 1999, Damsholt 2002). The frequently forked, three to seven spiral elaters appear to be unique in the genus (Kitagawa, pers. comm; Grolle, pers. comm.). The paroicous infloresence is shared by M. brevissima and M. sprucei, two other tiny, subalpine species in the genus.
Distribution: Growing on rocks, crowded into cracks in exposed sites; at first it was apparently restricted to the Cascade Mountains between Three Fingered Jack and Diamond Peak. More recently it has been found just north of the California-Oregon border in Josephine County and a review of collections made in 1980 uncovered a record from just north of Vancouver, B.C.
Comments: A very distinctive species which is fairly abundant in a small part of the western and central Cascades of Oregon. Not yet formally described.
