DR. MAXWELL T. MASTERS's CO^fTRIBUTIOXS 



In A. grandis, var. 

 Lowiana, the habit is 



generally rigid ; the 

 branches more formally 

 and closely verticillato 

 than in A. gran J is pro- 

 per; the branches rela- 

 tively stouter, shorter, 

 and diminishing in 

 length upwards more 

 abruptly, so that the 

 general outline is more 

 bluntly pyramidal. The 

 young shoots are flat, 

 olive-green or brownish, 

 shining. Buds elongate 

 ovoid, obtuse or pyra- 

 midal ; scales rounded, 

 brown, more or less re- 

 sinous. The leaves are 



dark 



green, linear ob- 



long, blunl (not notched 

 at the point), in few rows 

 (apparently only in two 

 rows), relatively very 

 Jong, generally all nearly 

 of the same length, 

 thinly set so as to ex- 

 pose the shoot, and 

 spreading horizontally 

 in a flat plane, some- 

 times upturned, and 

 given oflT nearly at 

 right angle (fig. g). 

 Stomata exist on both 

 surfiices. Even in acci- 

 dental cases, where the 

 leaves are contracted in 

 size owing to some check 



a 



growth 



aie all 



nearly of the same
