From the former it differs in the more gradually acuminate and 

 almost erect calyx-teeth, and from the latter in the short appressed 

 pubescence of the leaves, and the usually glabrous lower part of 

 the stem.

Stachys ampla sp. nov. 



Perennial, with a rootstock ; stem 5-7 dm. high, softly hirsute 

 and more or less viscid, especially above ; leaves ovate to lance- 

 olate, 5-10 cm. long, sessile or nearly so, rounded or subcordate 

 at the base, acute at the apex crenate-serrate, softly pubescent on 

 both sides and more or less glandular-granuliferous ; spike inter- 

 rupted, very leafy ; calyx soft-pubescent and glandular, about 9 

 mm. long ; lobes lance-subulate, spinulose-tipped ; corolla rose- 

 colored or pink, about 1 5 mm. long, somewhat puberulent without ; 

 lower lip very broad ; lateral lobes half as broad and three fourths 

 as long as the middle one. 



This species is related to 5. scopnlorum and 5. teucriformis 

 but differs from both in the larger corolla, the broader lower lip, 

 and the unusually large lateral lobes of the lip.

Audibertiella argentea sp. nov. 



A low shrub ; branches cinereous-puberulent ; leaves petioled, 

 1—2 cm. long ; blades rounded, obovate-spatulate, rounded or 

 retuse at the apex, scurfy-cinereous, at first silvery white ; bracts 

 broadly obovate, about 1 cm. long, membranous, strongly veined, 

 puberulent and ciliate ; corolla blue, about 1 cm. long ; lower lip 

 only slightly longer than the upper one, its lobes short and 

 rounded ; longer filaments about 12 mm. long, anther-bearing 

 connective 2.5-3 mm. long, sterile connective lacking. 



Dr. E. L. Greene* separated Audibertia polystachya Benth. from 

 the rest of the genus, as understood by Bentham and Gray, and 

 proposed the name Rauwna for this species. The other species he 

 reduced to Salvia. Briquet, ignorant of Greene's work, discov- 



* Pittonia 2 : 235.
