ARMED PLANTS, 181 



Dorycnium sujfmticosum owes its spinous 

 appearance to the rigid character of its short 

 branches (Holmes). 



The common Juniper, with narrow leaf and 

 black berry, is found in the mountain district and to 

 the west of Cannes. /. Oxycedrus, a taller tree with 

 larger fruit, occurs at Nice, and to the east. The 

 berries are red, and the leaf is broad with two white 

 lines. A third species (/. pkcenicea) may be found 

 here and there on the steep rocks. The scale-like 

 leaves are imbricate. Ardoino gives these localities : 

 Mentone, Monaco, Eze, St. Andre, St. Martin-du- 

 Var. 



A French botanical writer states that the 

 Juniper has the stomata more numerous on the upper 

 than on the under surface of the leaf. We should 

 expect a plant affected with so strange a peculiarity 

 to reverse the leaves, in order that the stomata may 

 not be exposed to the sunlight. It would be 

 interesting to observe whether this is effected by the 

 pendulous position of the twigs, or by the curving 

 axis which one sometimes sees in Junipers. I had a 

 small Juniper in my garden which bent over so much 

 that the leaves near the apex must have presented 

 their under surface to the sky. When I tied this 

 plant to a stick, so that it was forced to remain erect, 

 it died. The experiment would be worth repeating. 

 And it would be important to ascertain what is the 

 position of the stomata in those Junipers which 

 have the axis perfectly erect, and the twigs not 

 pendulous. 



The Oxycedrus Juniper, with its sharp tipped 

 leaves, is reasonably armed against attack. But
