24 Muhlenbergia, Volume 8 



In general aspect suggesting some form of nana^ but be- 

 longing according to floral characters to \.\\^ Pycnanthae section, 

 and most closely related to the next, from which it is readily 

 distinguished by the character of the pubescence. 



Type: Mount San Antonio, at about 9300 feet altitude, 

 Abrams 1928, July 24, 1901. The type specimen is in the 

 Dudley Herbarium. 



Distribution'. Known only from near the summit of Mt. 

 San Antonio. 



Specimens exaniiiied: Near the summit of Mt. San An- 

 tonio, Abrams 1928; Mrs. H. E. Wilder, August i, 1905. 



4. Moiiartlella australis sp. nov. 



Perennial from a woody rootstock, branches decumbent, 

 I to 1.5 dm. long, villous and pubescent: lower leaves reduced, 

 entire or remotely denticulate; cauline of 4 to 5 pairs, oblong- 

 lanceolate, mostly 15 mm. long, 6 mm. broad, thin, pale and 

 somewhat grayish-green with villous pubescence; lateral veins 

 evident, in 3 pairs: bracts ovate or broadly acuminate, 12 to 

 15 mm. long, membranaceous, light green tinged with pink, 

 sparsely villous and glandula:i calyx 8 mm. long, sparsely pu- 

 bescent, its teeth subulate, 1.5 mm. long: coiolla tube equaling 

 or slightly exceeding calyx, pubescent, lobes about 5 mm. long: 

 lower stamens a third longer than lower corolla lobes. 



This is probablv the most southern representative of the 

 odoi'-atis sim a grow'p. It is readily distinguished from true odor- 

 atissima, which was described from plants collected by Douglas 

 "in petrosis ad flumen Columbia et in rupibus alpestribus in 

 montibus White Montibus," by the acuminate instead of round- 

 ed bracts, as well as by fojiage and habit. The last two collec- 

 /tions cited below approach epilobioides, and eventually a large 

 series may form a complete intergradation between these two, 

 and through the variety of epilobioides connect up, by an un- 

 broken chain, the odoratissima and li)ioides groups. 



Type: Tamarack valley, altitude 9200 feet, vSan Jacinto 

 mountains, Hall 2486, J^^lVi 1901. The type specimen is de- 

 posited in the Dudley Herbarium.
