 leaves, etc.); /. Gossweileri (next L glomerafa OUv'ier and Hiern, but 

 with smaller radical leaves, larger flower heads, etc.); Bidens ainbi-

Arceuthobiuni occidentale fiowers from Sept. to January and the 

 iruits are ripe a year later. The fruits explode in damp air as a 

 result of the ieast disturbance, the conical seeds being projected to 

 a distance of 15 — 25 feet. The upper part of the fruit, cut off from 

 the rest by an oblique line, has a heavily cutinised thick epidermis 

 with many depressed stomata and subjacent parenchyma; the lower 

 hall has the epidermis scarcely cutinised and has stomata, while 

 there is a very gelatinous collenchyma underlying it which abuts on 

 the gelatinous seed-coat. At the point of attachment to the stalk
