tains of southern California which cannot be placed with any of 

 the described species. Specimens of this geographically isolated 

 maple have been known to us for several years, but we have 

 hesitated to describe the species, hoping that we might be able to 

 study the plants in the field. The prospects, however, of a field 

 acquaintance being still uncertain we shall describe the species 

 from the available material, which was collected by Mr. S. B. 

 Parish [^128) in Snow Canon, 6,500 feet altitude, San Bernardino 

 Mountains, June 20, 1901. 



^ Acer bernardinum sp. nov. 



A low bushy shrub, 15-20 dm. high ; branches slender, with 

 smooth whitish-gray bark. Leaves 15-25 mm. broad and about 

 the same length, cordate at base, 3-lobed to near the middle ; 

 central lobe as broad as long, with 2 shallow tooth-like lobes, 

 these with 2—3 short teeth; petioles slender, 10—12 mm. long. 

 Fruiting pedicels 1—3, 9—12 mm. long ; samaras strongly divergent. 



Nearest related to Acer Torreyi Greene, but distinguished by its 

 much smaller and less incised leaves, shorter petioles, and whitish- 

 gray instead of reddish twigs.

SHORTER NOTES 



BoTRYCHiUMS IN Sand. — The bay of Seven Islands is on the 

 north coast of the Gulf of St. Lawrence, about three hundred and 

 twenty-five miles below Quebec, or nearly half way from that 

 city to the straits of Belle Isle. The western shore of the bay 

 and the islands which fringe its mouth are composed of felspathic 

 rock, but the eastern shore is a continuous stretch of sand. This 

 sand region follows down the bay to the mouth, about four miles, 

 and then keeping the configuration of the coast bends to the east 

 and extends at least as far as Moisie, the next settlement, eighteen 

 miles away. Inland, the soil, if it can be so termed, consists of 

 sand dune aft2r sand dune of no great height, the whole thus form- 

 ing a belt of sand nearly twenty miles long and at first at least 

 four miles wide, with no trace of rock in the parts about to be 

 discussed, and probably with none anywhere. 



At the eastern entrance to the bay I was surprised to find last
