_ Dichelostemma insulare (Greene) 
Brodiaea tnsularis Greene, Bull. Cal. Acad. 2: 134. 1887. 
Plants closely resembling this species were found among 
old iron hoops at Searsville dam, May 11, 1895. The plants 
were large and stout, with leaves 4-7 mm. wide, and perhaps 
may be luxuriant specimens of D. capitatum. 
DICHELOSTEMMA MULTIFLORUM (Benth.) Heller 
This species is frequent in the mountains of northern Cali- 
fornia and the Sierras, but was not discovered south of San 
Francisco until April 13, 1894, on the hills west of the Palo 
Alto stock farm, growing with D. congestum which it closely 
resembles. It begins to flower about two weeks earlier than | 
congestum, and was in flower as late as May 18, 1895. 
ScOLIOPuS BIGELOVII Torr. 
Abundant in mountain woods at Summit Springs, west of 
Redwood City, February 24, 1894, and March 9, 1895. 
POLYGONUM EMERSUM (Michx.) Britton 
About a little pond on Weeks Brothers ranch, near La 
Honda, October 13, 1894. The surface of the pond was covered 
with Azolla filiculoides, and this is perhaps the station where 
Brandegee discovered the Azolla. The Polygonum is said to be 
rare in California. 
TISSA MACROTHECA (Hornem.) Britton 
Alkali soil, by roadside from the University to Searsville, 
January 6, 1895. 
RANUNCULUS CALIFORNICUS CANESCENS Greene

ruary 11 and November 17, 1894. 
DENDROMECON RIGIDUM Benth. 
A medium sized shrub with coriaceous entire leaves and 
solitary, large yellow flowers. Page Mill road to Black moun- 
tain, March 26 and May 8, 1895. Also collected in the Sierras,
