142 I^EAFLETS. 



tains, the flowering plant collected between CampbeU's and 

 Cameron's ranches, 21 June, 1894, by Edgar A. Mearns ; the 

 fruiting ones by the same collector between Pine Valley and 

 Laguna, 11 Aug. 1894. Among scarlet columbines of Cali- 

 fornia this one, strongly marked in character, is equally sin- 

 gular phenologically considered ; for its flowering appears to 

 take place in the dry season of the year. The 21st of June is 

 the time of the blooming of aestival rather than vernal flowers, 

 A. trjincata, to which A, hypolasia is somewhat related, comes 

 into flower in the coast mountains of even northern California 

 in April. 



AQUII.EGIA ADiANTOiDES. Slender and tall, 2 feet or more : 

 petioles of lower leaves 4 or 5 inches, 3 primary petiolules 1/^ 

 to 2 inches, all these sparsely and delicately villous-hirsute, 

 the short petiolules of individual leaflets quite densely so, the 

 sparse but distinct indument of both faces of leaflets as deli- 

 cate, but shorter and not spreading; leaflets of thin texture, 

 smallish and rather remote, all deeply ternate-incised and the 

 segments rather deeply crenate-lobed : flowers remote on long 

 suberect peduncles, these shortly and rather stiffly hirtellous, 

 especially so near the flower: sepals and petals scarlet, the 

 former rhomboidal, acuminate, unguiculate, deflexed, almost 



equalling the short spurs : anthers ellipsoidal : follicles not 

 seen. 



Species known only as collected by the late W. H. Brewer, 



at New Idria, California, 24 July, 1861, his n. 797 as in U. S. 



Herb., on sheet 320308. It is labelled in Prof. Brewer's 



hand A, Cayiadensis, As to habit, pubescence, lax, delicate 



finely cut adiantum-Iike foliage, as also its distinctly rhombic 



sepals, it is a thing wholly apart from A, triincata, so common 



in middle California, which flowers in April and May only; 



this southern one, strangely, in July and August, and that 



not as a mountain or subalpine plant, but as one belonging 



to a more arid and heated part of California than A. truncata 

 inhabits.
