cate-crowded : calyx and upper bracts tipped with scarlet: corolla 1 in. 

 long and more, surpassing the calyx, yellowish; lower lip short but 

 prominent, its callous oblong teeth rather shorter than the keel beneath; 

 upper lip nearly as long as the tube. In wet places among the coast 

 hills. April, May. 



2. C. latifolia, Hook. & Arn. Soft-hirsute and viscid perennial 12 

 ft. high, branched from the base: leaves round-obovaie to oval, I in. long, 

 sometimes 3 5-lobed, especially the scarlet -tipped floral ones: the 2 

 calyx-lobes broad, notched or 2-lobed at the apex, surpassing the corolla- 

 tube: lower lip of corolla short, the teeth inflexed; upper rather longer 

 than the tube. Moist slopes of hills near the sea. 



3. C. Douglasii, Benth. Sparsely and rather stiffly hirsute, 12 ft. 

 high: lower leaves linear, obtuse, entire, scarcely narrowed at base; 

 upper usually broader and cleft or incised; floral oblong, with an ovate 

 or oblong scarlet spot at tip: spike at length loose and interrupted: 

 calyx-lobes obovate, scarlet at the obtuse tips, shortly and broadly 2-lobed, 

 scarcely exceeding the lower lip of the corolla. Northward slopes of the 

 Coast Range; flowering almost all the year round. 



4. C. foliolosa, Hook. & Arn. Suffrutescent, branching, 13 ft. high, 

 hoary or nearly white with malted wool of intricately branched hairs: 

 leaves short and numerous, many densely fascicled on short axillary 

 branchlets, all linear and entire, or some with a pair of linear divaricate 

 lobes; upper floral cleft, and with yellow or scarlet tipped segments: the 

 2 calyx-lobes broad, retuse or merely notched, nearly equalling the corolla; 

 this with the lower lip very small. On exposed southward slopes; almost 

 always in flower. 



18. ORTHOCARPUS, Nutt. Ours all spring annuals, with cleft 

 foliage and often the colored-bracted spikes of Caslilleia; floral structure 

 much the same. Calyx 4-cleft, or cleft before and behind, and the 

 divisions 2-cleft. Corolla with upper lip not greatly exceeding the 

 lower in length, but the lower inflated and 3-plaited or 3-saccate. Sta- 

 mens in some with but one anther-cell. 



* Lower lip only moderately inflated, plaited-3-saccate for its whole 

 length: floral bracts more or less colored at the tips. 



1. 0. attenuatus, Gray. Slender, strict, 1 ft high or less, usually 

 simple, pubescent: leaves linear-attenuate, entire, with few lobes: spike 

 very long, narrow and lax; bracts with slender barely white-tipped divisions: 

 corolla very narrow, % in. long, whitish, with purple spots on the lower 

 lip, the narrow teeth of which nearly equal the upper. Plains and low 

 hills of the Napa and Sacramento valleys, etc. 



2. 0. (lensiflorus, Benth. Erect and simple, or branched from the 

 base, 610 in. high, soft-pubescent: leaves with few slender lobes, or the
