which Carex vitrea was founded, the only Carex known to reach 
even the borders of the desert. Selaginella Parishit completes 
the list of these type plants. It is common, growing about 
stones, and in rock crevices, often in company with S. Bigelovzi, 
the cismontane species. They are readily distinguishable by 
their gross characters; the creeping and rooting stems of the 
first species are flattened, while the stems of the second are quad- 
rangular and erect. 
There are other interesting canyons, Chino, Andreas and 
Murray, in each of which grow plants not found in any of the 
others. Our limited time, however, permitted us to visit only 
Palm canyon, at the extreme head of the valley. 
Just before entering it the road passes through a sandy wash, 
in which were growing many plants of Mimulus Bigelovit. On 
the right, in rough stony ground, grew Salvia Vasey1,* only a 
single shrub showing a few early Sones This is by no means 
a tare plant in the Colorado desert, but it has seldom been col- 
lected, as its season of flowering is later than that usually chosen 
by botanists for their desert.explorations. From the cliff on the

species. 
The canyon takes its name from the fine grove of fan palms 
which fill it for a mile or more, crowding the narrow stream 
bed, and straggling up the rugged sides. Few plants of interest 
were found here, the best being a few robust clumps of /uzcus 
es promis along the edge of the stream. The stems are
