portion or above, the lower pair liaving the inner edges ciliate, the upper pair having both edges 

 ciliate. All four filaments lie under the upper lip on the upper side of the corolla, closely parallel, 

 their edges eobwebby-connivent. The style lies between and behind the upper (or middle) pair 

 of stamens, which, being hirsute on the edges, weave a web of hairs over the style and thus hold it 

 in place. In California two varieties only occur, as noted below. 



Hairiness in Scutellaria angustif olia varies in different situations from puberulent to glandu- 

 lar-pubescent, from lightly canescent to subglabrous. The more markedly pubescent form (var. 

 CANESCENS Gray; fig. 423) inhabits mostly dry slopes or flats or rocky outcrops and occurs in 

 scattered localities in the hiUs and mountains almost throughout cismontane California. It differs 

 from the var. austinae only trivially in details of character but such collections as nuiy jjass for 

 var. canesoens are associated in the following list of citations. S. Cal.: Santa Eosa Mts., Mum

A less pubescent or subglabrous form (var. austi- 

 nae Leonard) has velvety deep purple corollas and in- 

 habits moist "bottoms" of streams or wet spots near 

 springs. It does not segregate geographically from the 

 pubescent form, var. canescens Gray, in any clear or 

 definite manner, but is often found at somewhat higher 

 altitudes and most often in areas of higher rainfall.

Field note. — As to the biological type (prevailing form) Scutellaria antirrliinoides has shorter
