8. H. suaveolens R. Br. II. pectinata Colla. 



A dense rounded shrub becoming 8 to 10 ft. high in California: 

 young shoots and foliage silky pubescent but glabrous at maturity: 

 leaves 2 to 4 in. long, about yQ in. thick, cylindric, with a rigid spine- 

 like tip, narrowly grooved on the upper side, occasionally entire but 

 usually branched into 1 to 5 rigid cylindric lobes of various lengths: 

 pedicels and perianth glabrous: flowers white, fragrant: capsule ovoid, 

 about 1 in. long and % in. broad, narrowed at apex and with a small 

 conical horn near the end of one or both the valves. Illustration: Fig. 7. 



This is perhaps the most common of all the cultivated Hakeas. 

 It is easily grown, endures drought, and, by means of its spiny

foliage, resists the depredations of animals and vandals. For 

 public parks, depot grounds, and the like, no shrub could be 

 selected which would be better able to care for itself, and it is 

 eminently adapted to planting where an impenetrable hedge is 

 desired. In the vicinity of Santa Barbara, it grows without 

 care or irrigation on the dry hillsides and would undoubtedly 

 make an excellent chaparral covering for many of our mountain 

 slopes. 



9. H. acicularis R. Br. 



A tall shrub or (in Australia) a small bushy tree: twigs and young 

 leaves sometimes minutely pubescent, glabrous when mature: leaves very 

 slenderly cylindric, rigid, awl-like at the sharp tip, entire and simple, 

 not grooved, mostly about 2 in. long (1 to 3 in.) : pedicels silky-pubescent: 

 corolla glabrous: capsule ovoid, about 1 in. long and % in* r rather 

 more broad, rough, contracted to a thick beak, each valve with a conic 

 brown horn near the apex. 



Suitable for hedges and for shrubberies. More slender than 

 H. suaveolens.
