mens suggests, that it may be a hybrid product of Audiber- 

 tia stachyoides fertilized by Salvia Columbarice. The structure 

 of the corolla is that of the Salvia, even to the polliniferous 

 lower anther-cell. 



Salvia (Calosphace) Cedrosensis. 



Shrub 1 — 3 feet high, branches white-tomentose, the hairs 

 branching: leaves green and not rugose above, white be- 

 neath, ovate, with cuneate, truncate or cordate base, crenate, 

 6 — 10 lines long, on short petioles: flowers in short, rather 

 dense, naked racemes: calyx funnelform, four lines long, 

 striate-veined, the three very short lobes entire, mucronate- 

 pointed; pedicel less than a line long: corolla deep blue, 

 twice the length of the calyx : filaments naked : style villous 

 above. 



Cedros Island, April 28, 1885. Common at middle and 

 higher elevations. Related to S. ballota>flora and S. plat- 

 ycheila. 



Polygonum (Avicularia) Austinae. 



Erect-spreading, branching from the base, a span high, 

 glabrous except the minutely scabrous angles of the branches 

 near the joints: leaves ovate-lanceolate, acute, sessile, a half 

 inch long, the floral much reduced: stipules short-campanu- 

 late, not lacerate : flowers in all the axils, mostly a pair in 

 each: pedicels very short, abruptly deflexed: sepals obtuse, 

 completely and closely investing the rather narrowly ovate, 

 smooth and shining akene. 



Modoc County, on the northern border of the State, on 

 sage-brush plains; Mrs. R. M. Austin, 1884-5. The species 

 closely resembles P. Engelmanni (see page 126), but has 

 broader leaves, entire stipules, and a thrice larger nutlet, 

 which does not, in maturity even, at all surpass the peri- 

 anth. 



Pterostegia fruticosa. 



Shrubby, diffusely branched, firmly erect, 2 — i. feet high,
