Evelyn's Sylva, by Hunter, p. 223. See Quarterly Review. No. 44.

 374. and '^ Curiosities for the Ingenious." Duod. pages 155. to 161. 

 " The divining-rod when held in a certain position, and under 

 certain circumstances, is said to discover the situation of metals, 

 &c. in the earth, by dipping as it approaches the place beneath 

 which they immediately lie." 



Class XXII. DIOECIA. Stamens and 

 Pistils in separate Jlowei^s, on different plants. 



{MONANDRIA. Stamen I.) 



Several willows. Sm. 



DIANDRIA. 



SALIX. Willow, Sallow, and Osier. 



Linnaeus observes, that the species of this genus are made out 

 with very great difficulty. Sp. PI. 1449. 



The differences found in the germens, styles, and stigmas, toge- 

 ther with the shape of the leaves, afford good specific marks for the 

 discrimination of Salices. Seasons for studying the Salices, or 

 Willows, are 1st. their flowering time : 2ndly, the early part of 

 summer, to observe their stipulas, before the leaves come to their 

 full size, and 3rdly, w^hen the leaves come to their full size. Tliey 

 must be observed in their growing state for several seasons, to be 

 well discriminated. The flowering period of willows is of short 

 duration, during the greatest part of the summer we have no 

 flowei's to assist our investigations. The willows afford food for 

 a great variety of insects. The large excrescences, on the branches 

 and leaves of willows, are the nests of different species of insects 

 (the Cynips.) The stamen -bearing willows should alone be planted 

 in walks : the pistil-bearing ones multiply too fast, and form a 

 thicket. • 



* Full grown leaves saw-toothed, smooth, or nearly so. 



S. triandra. Long-leaved Triandrous IV. Leaves 

 linear-oblong, saw-toothed, smooth ; rather unequally- 

 sloping at the base. Stamens generally three. Ger- 

 men stalked, egg-shaped, compressed, smooth. Stig^ 

 mas nearly stalkless. E. B. 1435. 



Wet woods, hedges, osier-grounds. 



1 The Botanist will find a valuable collection of Grasses, British AVillows, 

 and Roses, cultivated in the Botanic Garden, Oxford. Several Willows have 

 been lately planted round Christ-chureh Meadow.
