4. C. linearis DC. 



Scarcely more than a variety of C. rigidus, being the extreme form 

 with very narrow leaves which are channeled above, and the midvein 

 quite obscure; fruiting calyx more globular and more contracted at the 

 opening.

5. C. salignus DC. 



A tall shrub or small tree (6 to 10 ft. high, in Australia reaching 40 

 or 50 ft.): leaves broadly to narrowly lanceolate, very acute, 1% to 3 

 in. long, mostly y to % in. wide, but much narrower in one variety, 

 very distinctly feather-veined: flower-clusters pale yellow or light pink, 

 1 to 2 in. long, % to 1 in. wide: stamens % to ^ in. long: capsule nearly 

 globular, with rather large opening. Illustration: Bot. Mag., pi. 1821. 

 Var. viridiflorus F. Muell. has leaves only 1 to 2 in. long, thicker, the 

 veins obscure, rigid and sharp-pointed: flowers larger, greenish yellow: 

 habit more erect, rigid, and tree-like. Illustrations: Fig. 12; Bot. Mag., 

 pi. 2602. 



Rare in California gardens and* not especially desirable. The 

 wood, which is very hard and close-grained, is said to be very 

 durable underground and to dress admirably. It varies from 

 a uniform drab color to dark red.
