RARE OR LITTLE-KNOWN SPECIES IN NEED OF 
COLLECTION 
For California there are records of hundreds of species 
of native flowering plants which have been collected 
only once and specimens of which do not exist in cob 
lections in California. Many others still have been 
collected in only a single stage or are imperfectly 
known from certain areas. It is my purpose to give 
a list of such flowering plants from time to time in 
order that parties on trips may add special or addi- 
tional objectives to their field work. 
Calla palustris L. Reported from Glen Blair, Men- 
docino County, as if endemic (Zoe, 5:58). 
Plectritis nitida. Heller. Crystal Springs, San Mateo 
County, April or May. 
Plectritis collina Heller. Mt. Hamilton, April or May. 
Sanicula saxatilis Greene, Mt. Diablo, May. 
Cicuta califoraica Gray, Leona Heights, July. 
Euloplus califomicus C. & R. Arroyo Hondo, Mt. 
Day, in Mt. Hamilton Range. This is a very remark- 
able parsley and field notes should be taken. June. 
Howellia limosa Greene. Suisun, pools, April. 
Downingia humilis Greene. Los Guilieos Valley, April 
or May. 
Ranunculus Biolettii Greene. Los Guilicos Valley, 
April or May. 
Downingia cuspidata Greene. Grain fields west of 
Yountville, April or May. 
Osmorrhiza nuda Torr. Although the type was col- 
lected in “Napa Valley’ ’ in 1854 by Bigelow no speci- 
men from that region is available to us to this day. 
Malvastrum marrubiodes D. & H. Ft. Miller, Fresno 
County, foothills. Also at same locality, Hosackia 
lathyroides D. & H. and Godetia Williamsonii D. & H. 
Sidalcea rostrata Eastw. Mendocino City, May. 
Juneus supiniformis Engelm. Ponds at Mendocino 
City. Probably May or June. Fruiting parts of this 
appear to be unknown in California collections. 
Osmorrhiza bolanderi Gray. Lambert Lake, Mendo- 
cino County. This Sweet Cicely is not definitely known 
in California herbaria; the species is something of a 
mystery. 
Heteranthera dubia MacM. Mendocino County. Col- 
lected 50 or 60 years ago by Vasey and not since re- 
discovered. A curious aquatic with yellow flowers. 
The month indicated is only approximate. Directions 
for collecting were given in Nemophila No. 3.— W. L. 
Jepson, University of California* Berkeley.
