FABACEAE Reichb. Consp. 149. 1828. 

 Lathyrus Bolanderi Wats. Proc. Am. Acad. 30: 363. 1885. 

 No. 8583, collected May 28, about three miles beyond Sau 

 Mateo, San Mateo county, on the Half Moon Bay road, climb- 

 ing over bushes. The type was from "thickets, Oakland Hills, 

 Bolander and Dr. Torrey in 1865." Watson says the leaflets 

 are "obtuse or retuse or acute." In the specimen before me 

 they are acute, short!}- apicnlate. He also says "calyx teeth 

 broad," which is not the case in our plant. In other respects it 

 seems to agree, so far as one can tell from the description. 



Lathyrus puberulus White; G-^eene, Manual 85. 1894. 



No. 8454, collected April 20, on the western end of the San 

 Bruno hills, San Mateo county, elevation about 600 feet, grow- 

 ing on open rocky hills in a tangle of other vegetation. The 

 given range is "Sonoma county southward." I have collected it 

 in Sonoma county and in Santa Clara county about Log Gatos. 

 It blooms earlier than any other Lathyrus in the Bay region. 



No. 8480, collected April 27, in woods back of Alum Rock 

 Park, Santa Clara county, elevation about 700 feet, climbing 

 over shrubs. This plant may be distinct as it has thinner, paler 

 leaves than typical pubej^iiliis^ and the calyx lobes somewhat 

 narrower. 



Lathyrus quercetoriiin 



Low and rather rigid, erect or nearly .'^o, 3 dm. high, the 

 stems angled but not winged, pubescent with appressed white 

 hairs, leafy throughout: leaves tendril bearing, about i dm. long; 

 leaflets in five or six pairs, elliptical-lanceolate, acute and cus- 

 pidate, 3 cm. or less long, the largest i cm wide at the middle, 

 rather thin but firm, light green above, paler beneath, lightly 

 flocculent on both sides, veins prominent beneath; petiolules 

 I mm. long: stipules semi-sagittate, acute, less than half the size 

 of the leaflets, the upper lobe entire, the basal one sometimes 

 slightl)' toothed: flower stalks about as long or commonly .shorter
