 treat indeed. 



When some genius invents a chauffeur who can be started 

 and stopped — especially stopped — by pressing a button like 

 other parts of the mechainsm, then in truth will the cup of

NOTES ON OREGON PLANTS 



By R. V. Brads HAW. 



Touring the past summer a peculiar water plant came under 

 ■*-^my observation. It was found growing on the rocks in the 

 Willamette River not far from Eugene. During high water 

 these rocks are submerged, but in the dry season they project 

 far out of the stream. The plant is unable to flourish out of 

 the water, for as the water goes down it is killed by the hot 

 sun and drought. In appearance it suggests a moss, but the 

 branches are filifcjrm, stiff and have no leaves. They are 

 bright green and present a rather jointed effect, the joints 

 being a darker green than the other parts. They are tufted 

 and issue from the base directly and do not l)ranch further. 

 Besides these, at the base also arise little bladder-like organs 

 which are open at the top and resemble a small empty caddis- 

 fly case. These bladders were about 5mm. long and were 

 about 2mm. wide. The tufted branches were nearly 7mm. 

 I'ing. This interesting plant was determined by Dr. Howe of 

 the New York Botanical Garden, who calls it Lcmanea fiicina 

 rigida. It is one of the few red algae that inhabit fresh 

 water.
