SALISBURIA. 373 



ably elevated rib, marked on each side with glaucous bauds 

 on the under one, furnished with a very short foot-stalk at the 

 base, and terminating at the summit in an acute point, some- 

 times a little rounded. Male catkins in terminal spikes or 

 racemes ; female flowers in spherical heads in the form of a 

 little cone, on long, slender, terminal foot-stalks, sometimes 

 drooping. Fruit composed of several consolidated free scales, 

 formed into a solid fleshy cone, of a depressed form, with a 

 very irregular surface, owing to many of the scales being 

 abortive, while the ends of the whole retain their original 

 form, are free, rather spiny, and constitute so many tougb, 

 sharp tubercles, pointing in all directions. Seeds, a pale 

 brown, glossy, ovate nut, with a short, thin, jagged membrane, 

 enveloping the base of the seed only. 



A small tree or bush, growing thirty feet high on the moun- 

 tains of Patagonia, with very much the appearance of the 

 common yew, but wanting its fine sombre green. 



It is called '' Maniu " and " Pino " by the Chilians, and is 

 more or less tender. 



Gen. SALISBUKIA. Smith. The Maiden-hair 

 or Ginkgo Tree. 



Flowers dioecious, or male and female on different plants; 

 the males in spikes, axillary, and without foot-stalks ; the fe- 

 males in terminal clusters, on long petioles. 



Fruit drupaceous, or covered with a fleshy pulp, and smooth 

 externally, mostly single from abortion, and enclosed at the base 

 in a small fleshy cup. 



Seeds solitary in each fruit, and covered with a smooth, hard, 



bony shell. 



Leaves fan -shaped, on long foot-stalks, lobed, and jagged on 

 the outer margins, and covered on both sides with minute fan- 

 shaped, straight nerves.
