TRIFOLIUM ACICULARE Nutt. 
-. A common clover in orchards, along roadsides, or in grassy 
fields. The purplish corollas are showy, the banner marked 
with a deep purple spot. The narrow leaflets end in a conspic- 
uous apiculation. It has commonly been confused with 7. érz- 
dentatum. 
TRIFOLIUM BIFIDUM Gray 
This species, originally from Contra Costa county near Mt. 
Diablo, is rather plentiful on the hills about Los Gatos, growing 
in fields or about thickets. ‘The narrow leaflets are deeply 
notched, the flowers small and pale. 
‘TRIFOLIUM GRACILENTUM T. & G. 
Common in fields and orchards, an almost prostrate mat 
like form abundant at places in the hills) The flowers vary 
from almost salmon color to deep purple-red. 
TRIFOLIUM MICRODON H. & A. 
A small plant, often hidden among other clovers. The 
pale flowers are subtended by a conspicuous involucre with a 
truncate base. It is rather common on open hillsides. 
TRIFOLIUM NEOLAGOPUS Loja. 
A variable plant, sometimes small and sometimes large, the 
small purple flowers usually concealed by the long dove colored 
calyx lobes. Our plant has been confused with several species, 
notably columbinum and albopurpureum, but it seems to be this 
long unrecognized species. It is rather commen on our hills 
and widely distributed from this point southward to at least 
Riverside county. 
TRIFOLIUM OLIGANTHUM Steud. 
A slender plant with few small pale flowers, the leaves nar- 
row. With us it occurs on grassy hillsides in gravelly soil, or 
even in orchards.
