EUCALYPTUS BEHRIANA. 



The stomata of the leaves are not always isogenous, as recorded before, but have been found to 

 be also 91,000 on a square inch of the upper page and 104,000 on the lower page ; this diversity 

 arises probably from the age of the plant. 



This species was named by me already in 1849 after Dr. Herman Behr, by whom it was then 

 discovered in South Australia, and where already by his prior travels he had shed much light on 

 the Flora and Fauna ; this ardour for scientific research was displayed by him unabated for the 

 last thirty years in California, where he more particularly has contributed to the entomologic 

 elucidation of that country. 



EXPLANATION OF ANALYTIC DETAILS. 1, an unexpanded flower, its lid lifted ; 2, longitudinal section of an 

 unexpanded flower; 3, some stamens in situ; 4 and 5, back- and front-view of an anther with portion of its 

 filament; 6, style and stigma; 7 and 8, longitudinal and transverse section of a fruit; 9 and 10, fertile and 

 sterile seeds ; 11, portion of a leaf ; all magnified, but to various extent. 



EXPLANATION OF ANATOMIC PLATE. Transverse sections of the wood of Eucalyptus amygdalina, E. Behriana, 

 E. botryoides, E. globulus, E. goniocalyx, E. Gunnii, E. hemiphloia, E. nmcrorrhyncha, E. melliodora, E. obliqua, 

 E. polyanthema, E. punctata, E. rostrata, E. Sieberiana, E. Stuartiana, and E. viminalis. The large openings 

 represent the vascular tubes ; the rows of elongated cells constitute the medullary rays ; the scattered cells and 

 those near the vascular openings exhibit parenchyma ; the multitudes of smallest apertures indicate the closely set 

 wood-fibres. Augmentation 80 times. (These microscopic sections are given to aid in the discrimination of mer- 

 cantile Eucalyptus-timber of doubtful origin, such as sometimes occurs in the trade.)
