tree withstands the effect of salt water by means of its thick, 

 impervious bark. The leaves of certain forms yield cajuput oil, 

 an article of commerce used in medicine. 



8. M. styphelioides Sm. 



Becoming a tall tree, with thick spongy bark; young shoots and 

 inflorescence silky, the herbage otherwise glabrous: leaves alternate, 

 ovate, sessile by a broad base, tapering above to a sharp rigid tip, usually 

 more or less twisted, % in. long, nearly 14 in. wide, striate with numerous 

 fine nerves: flower-clusters creamy- white, dense, 1 or 2 in. long, nearly 1 

 in. wide, the axis growing out before flowering is over: stamens slightly 

 exceeding 14 i n - i n length: capsule globular, crowned by the persistent 

 calyx-teeth. Illustration: PI. 4, fig. 4. 



'Cultivated, so far as I know, only around San Diego but 

 should be more generally used. The largest specimens are now 

 large shrubs of neat appearance and with much clean, thrifty 

 growth. 



9. M. armillaris Sm. 



A tall shrub, of graceful habit, glabrous throughout: bark gray, firm, 

 furrowed, deciduous in narrow strips: leaves densely clothing the long 

 slender twigs, alternate, narrowly linear, the tip very slender and usually 

 curved outward, % to % in. long, less than y lQ in. wide: flower-clusters 

 white, cylindric, over 2 in. long when well developed, % in. wide, the 

 axis protruding and leafy before the buds open: stamens *4 in. long, the 

 ribbon-like claw about as long as the free filaments: capsule with broad 

 base partly embedded in the stem. Illustrations: PI. 4, fig. 2; pi. 6; 

 Cav. Icon., pi. 335 (bad) ; Bot. Cook's First Voy., p. 114. 



This I consider the best of the white-flowered sorts. Espe- 

 cially suited to shrubberies and borders of broad walks where 

 something graceful is desired. By means of a little heading 

 in it may be made to assume a rounded form with many slender, 

 drooping branchlets, each densely clothed with the abundant 

 narrow foliage. This absence of barren twigs and of knotted 

 fruit-clusters is one of its chief advantages. Specimens have 

 grown to a height of 7 feet in two years at Santa Barbara, while 

 shrubs 20 years old at Coronado are only 15 feet high. Much 

 used at West Lake Park, Los Angeles, often as a shelter for the 

 park benches. Does fully as well at San Mateo, San Francisco, 

 etc., but perhaps of slower growth. Said to attain 20 to 30 feet 

 in Australia. Often called M. alba in California gardens.
