and the keel petals are actually ciliate as in L. nanus, although 
the ciliated edges are more or less curved inward so as to make 
the ciliation less conspicuous than usual. I could easily pass this 
specimen as a large phase of L. manus without an inclination to 
seek even a varietal name for it. However, the California 
Academy has a sheet labelled the same as the above, except 
as to specific locality, which is given as ‘‘ Point Reyes.’’ This 
is a more marked variation from typical L. nanus, and agrees with 
certain San Mateo County specimens also identified by Greene 
as L. carnosulus. As this form is what has been accepted by 
others under Greene’s name, I consider it wiser to suggest no 
change of name here, except to place the plant where it belongs,

as a variety of L. manus. I have visited several of the localities 
where the variety has been found by others, both at flowering 
and fruiting season, and find the size of pods and seeds the only 
reliable characters for satisfactory identification. Miss Harriet 
L. Walker, in May, 1913, and myself, in May, 1921, visited 
Olema and vicinity seeking fruiting specimens and information 
concerning L. carnosulus. We each found L. nanus, sensu 
stricto, abundant and in full bloom, but no evidence of the large- 
fruited variety. However, Greene also took a plant at Olema, 
16 April, 1886, which he labelled, “ZL. nanus’ * (UC 196349). 
I have seen no specimens with ‘naked keel.’
