many branches or in terminal clusters or heads. Bracts 

 and calyx never colored. Calyx spathe-like, consisting 

 of an anterior and a posterior leaf-like division or the 

 anterior division wanting. Corolla tubular, somewhat 

 enlarged above; its lips about equal in length, the lower 

 obtusely 3-toothed. Stamens 4 or 2, anther-cells un- 

 equal, ciliate or minutely bearded. Capsule flattened; 

 seeds with a loose coat, pointed at one end. 



1. A. filifolia (Nutt.) Abrams. Stems erect, branched, 3-6 dm. 

 high; leaves all filiform, 3-parted to near the base; herbage pubescent 

 with short reflexed hairs intermingled with scattered spreading 

 hispid hairs; heads several-flowered, terminating the branches; 

 bracts 3-lobed to near the base, the entire portion about 1 mm. 

 broad, strongly 3-nerved; the lobes all filiform and usually nearly 

 equal, the outer surface very hispid with stout spreading hairs 

 rising from postulate bases, the inner surface concave, pubescent, 

 slightly elongated at the apex and tipped with a blackish, more or 

 less retuse gland; corolla purplish, 12-15 mm. long. {Cordylanthus 

 filifolius Nutt.) 



Common on dry ridges in the chaparral belt of all the mountains. 

 Adenostegia rigida Benth., to which our southern plants have been 

 referred, has broader leaves and bracts which are less hispid. 



2. A. maritima (Nutt.) Greene. Corymbosely branched, 1-3 

 dm. high; herbage glaucous and more or less hoary-pubescent, 

 often tinged with purple; leaves linear to linear-lanceolate, about 

 2 cm. long, entire; flowers in short spikes; bracts oblong-lanceolate, 

 entire or commonly 3-toothed, the 2 lateral teeth much the smaller; 

 flowers purple, equaling or slightly exceeding the bracts. 



Occasional in salt marshes near the sea. June-September. 



14. PEDICULARIS L. 



Perennial herbs with alternate opposite or rarely 

 verticillate pinnately lobed cleft or pinnatifid leaves, 

 and irregular flowers in terminal spikes or spike-like 

 racemes. Calyx 2-5-cleft, corolla tubular, strongly 

 bilabiate; galea arched and compressed; lower lip of 3 

 small rounded lobes or teeth. Stamens 4; anthers 

 approximate in pairs, their sacs transverse, equal. Cap- 

 sule flattened, oblique at apex, loculicidally 2-valved. 



1. P. densiflora Benth. Stems simple, erect, 2-3 dm. high, 

 commonly several from the scaly caudex; herbage nearly glabrous 

 or somewhat soft-pubescent; leaves pinnately divided or parted, the 

 segments oblong, doubly serrate-toothed or incised; spike terminal, 

 dense or at length loose; bracts linear, ciliate or serrulate toward the 

 apex, mostly shorter than the flowers; calyx 5-angled, equally or 

 unequally 5-toothed, 6-8 mm. long; corolla crimson, 2.5 cm. long
