beneath very closely white-woolly between the reticulate veins : panicle 

 of cymes naked: corolla pale blue, tubular-funnelform, thrice the length 

 of the sparsely hairy calyx. Dry hills in the sparsely wooded mountain 

 districts. May July. 



OEDER LXXII. ASPERIFOLI/E. 



Plants intimately connected with HydrophyUaceaz, the herbage in 

 general still more pronouncedly rough-hairy or hispid, but less succu- 

 lent. Inflorescence equally unilateral and scorpioid. Differing in that 

 the single style is surrounded at base by a 4-lobed ovary, which ripens 

 into 4 (or by abortion 2) usually distinct and very seed-like nutlets. The 

 5-cleft or -parted calyx mostly persistent; corolla deciduous, in ours 

 mostly short-salverform and the throat closed by folds. 



* Corolla imbricate or quincuncial in estivation. 



Nutlets depressed and horizontally extended; 



Nutlets rounded, the whole surface rough CYNOGLOSSUM 1

1. CYNOGLOSSUM, Diosc. Calyx 5-parted, persistent, open in fruit. 

 Corolla short-salverform, with conspicuous arching crests at the throat 

 concealing the short stamens and pistil. Nutlets 4, broad, depressed, 

 the whole back covered with short stout prickles having minutely barbed 

 tips, oblique or horizontal, separating at maturity from below upwards, 

 and for a time suspended on a process connected with the style. 



1. C. grande, Dougl. Perennial, stout, 2 ft. high, with long-pet- 

 ioled ovate-oblong leaves often a foot long, usually rounded at base, 

 pubescent with soft slender hairs : panicle of short racemes small, on a 

 long naked peduncle terminating the short leafy stem: corolla % in. 

 broad, deep blue, with pinkish central folds. In shades along streams, 

 and on northward slopes. Jan. April. 



2. PECTOCARYA, De Can dolle. Low slender annuals, with strigose- 

 hirsute pubescence, small narrow leaves, and small flowers near their
