Pogogyne. LABIAT^E. 597 



sweet-aromatic ; with oblong or oblanceolate mostly entire leaves, narrowed into a 

 petiole ; flowers mostly crowded and interrupted spicate ; bracts and calyx hirsute- 

 ciliate, the teeth of the latter mostly 3-nerved; the corolla blue or purplish. Benth. 

 Lab. 414. 



1. Stamens all four with anthers : style conspicuously bearded above, and its subulate 

 lobes almost equal : corolla (6 to 9 lines long) tubular-funnelform, the tube 

 surpassing the calyx (calyx-teeth variable). 



* Flower-clusters densely crowded into an oblong or cylindrical spike, which is con- 

 spicuously white-hirsute with the long and stiff ciliate hairs of the bracts and 

 calyx. 



1. P. Douglasii, Benth. Eather stout, a span to a foot high: leaves oblong, 

 spatulate, or oblanceolate, veiny, sometimes sparingly toothed: spikes dense : bracts 

 linear, acute : lower divisions of the calyx twice or thrice the length of the tube 

 and much longer and narrower than the others : corolla half to three fourths of an 

 inch long, blue, or sometimes purplish. Hook. Bot. Mag. t. 5886. P. multiflora, 

 Benth. Lab. &c., a smaller form with rather shorter bracts. 



Open and shady grounds, throughout the western part of the State and into the foot-hills of the 

 Sierra Nevada. 



2. P. parviflora, Benth. More slender, 5 to 8 inches high : leaves narrower : 

 spike shorter : bracts mostly obtuse : divisions of the calyx rather broad, the lower 

 hardly longer and the upper shorter than its tube : corolla barely half an inch long. 



San Francisco Bay to Mendocino Co., Douglas, Bolander, &c. 



* * Whorl-like flower-clusters more or less distant : bracts and calyx sparsely and 



rather slightly hirsute-ciliate. 



3. P. nudiuscula, Gray. A span to a foot high, with slender puberulent 

 branches : leaves spatulate or linear-spatulate, obtuse (an inch or less in length), 

 glabrous : bracts linear-subulate and cuspidate : corolla half an inch long, twice the 

 length of the calyx : anthers of the posterior stamens usually smaller than the 

 others, but polliniferous. 



Near San Diego, D. Cleveland. Calyx-lobes lanceolate-subulate or linear-subulate, in the later 

 flowers all twice or thrice the length of the tube, but in some of the earlier ones little longer than 

 the tube. 



2. Upper stamens sterile : style sparingly hairy, its lobes very unequal : flowers 

 small. HEDEOMOIDES, Gray. 



* Tube of the corolla slender and manifestly exceeding the calyx, 4 or 5 lines long : 



inflorescence capitate. 



4. P. tenuiflora, Gray. A span or less in height, puberulent or at the summit 

 pubescent, corymbosely branched or simple : leaves spatulate or obovate, their peti- 

 oles and the narrow bracts slightly and sparsely and sometimes not at all bristly- 

 ciliate : calyx-lobes unequal, linear-lanceolate, about half the length of the filiform 

 tube of the corolla : sterile filaments tipped with a small capitate gland. Proc. 

 Am. Acad. xi. 100. 



Guadalupe Island, Lower California, Dr. Palmer. Added to complete the account of the genus. 

 * * Corolla at most 2 lines long, little if at all surpassing the calyx. 



5. P. ziziphoroid.es, Benth. Stems 2 to 6 inches high : leaves ovate or oval, 

 thickish ; the floral with the rigid narrow bracts and the calyx hirsute-ciliate with 

 strong white hairs : inflorescence capitate or spicate, sometimes interrupted, or with 

 a few solitary flowers in the lower axils : calyx-lobes slightly unequal, broadly lan- 

 ceolate, very acute, hardly twice the length of the tube, the longer equalling the
