When the Californian plants now referred to micranthus are 

 carefully studied, they will be found to consist of a mixture of 

 several species, and none of thetn closely related to true micran- 

 thus unless perhaps L. umbellatits^ which I suspect is often 

 labeled micranthus in southern California.

As recently pointed out by Professor C. P. Smith in this 

 journal (6: 136), the plants which in California have commonly 

 been called L. bicolor are not that species at all. He, however, 

 was not the first to call attention to the matter, for in Flora 

 Franciscana 39, Greene notes: "Sandy soil about San Francisco, 

 in a slender depressed very hairy form; also on gravelly crests 

 of the Oakland Hills, where it is stouter, with ascending 

 branches. The two may well be distinct species; and neither 

 plant agrees perfectly with the original L. bicolor of the Colum- 

 bia River." The plant from the Oakland hills was no doubt 

 Greene's L. apricus. 



Under the original description, the habitat of this species is 

 given as "in the interior of the country about the Columbia 

 River, from Fort Vancouver to the branches of Lewis and 

 Clark's River, always on dry gravelly soil under the shade of 

 trees in the open plains" 



Fort Vancouver was located in what is now known as Mill 

 Plain, a short distance from the present thriving lown of Van- 

 couver, Wash. Our own government now maintains an import- 

 ant army post at Vancouver, but the Fort Vancouver of Douglas' 

 time was maintained by an English fur company. 



Last May it was ni)- privilege to visit Vancouver, and the 

 first plant collected after proceeding up the river past the inclo- 

 sure of the military reservation vi^^s, Lupiints bicolor^ growing on 

 an open grass)' slope wilhin the town limits, or at least inside 

 the built-up portion. But there were no trees there to shade it, 

 although they may have been there in former times. From the
