﻿94 PLANTS PRATTENNIAN.E CALIFORNIA. 



Stem erect, ramose, 2 — 3 feet high, slightly puberulent and glaucescent. Inflo- 

 rescence, before the expansion of flowers, very similar to that of prainanthes. The 

 upper cauline leaves are sessile, lanceolate, acute, widening towards the base, with 

 two small teeth on each side. Flowers medium size, about \" long, blue and some- 

 what drooping, 3 — 5 paniculate, in an elongated and loose spike ramulose at base ; 

 tube of the calyx globose, truncate, with acute lobes, scarcely one-half the length of 

 the corolla, which is campanulate and deeply divided in lanceolate lobes. Style 

 exserted, reflex, stigma clavate, with three short and erect divisions. The specimens 

 are very incomplete, and exhibit only the tops of the branches.

 exertissimis ; antheris elongatis, apice truncato biporosis ; stylo stamina superante,
