• Acrolasia tridentata. n. sp. 



By Dr. Anstruther Davidson. 



Low annual, short-caulescent, 5-7 cm. high; leaves lanceo- 

 late ovate, coarsely toothed, 2-3 cm. long, tapering to a broad. 

 short petiole, midrib well marked underneath; flower 15 mm. 

 long, short peduncled, and devoid of bracts; sepals <> mm. 

 long, lanceolate acute; petals five, light yellow. 12 mm. long. 

 lanceolate ovate; filaments all expanded in lower half into 

 flat bands, 1 mm. wide, and 3 mm. long, terminating above 

 in three short teeth, the central one bearing the remainder 

 of the filament and anther; fruit unknown. Whole plant is 

 rough with the retrorse prickles of the genus, the bases of 

 the leaves. ;itid base of the flower pilose. 



This phmt comes nearest A. tricuspis (dray), but it is 

 much smaller and more hoary, and has not the conspicuous 

 pale bracts of that species. The peculiar dilatation of the 

 basal part of the filamenl easily distinguishes it from others 

 of the genus. Type 24<>(). Ilasse & Davidson. Banks of 

 Haiwee Reservoir, Inyo County, April 2(i. 1910.
