206 TAMARISK 



The Cedar is the only similar tree, but that is ever- 

 green and has very different cones (see p. 137). 



(ii) Buds not on tuberculate dwarf-shoots, or 

 nodulose twigs bearing cones. 



(a) Buds minute, subtended by minute pro- 

 minent bases of scale-leaves, and very 

 numerous but many abortive; on slender 

 twigs crowded with small imbricated grey- 

 green scale-like leaves. 



Tamarix gallica, L. Tamarisk. The habit is somewhat 

 Cypress-like or Ericoid (see p. 142), a resemblance en- 

 hanced by the sub-evergreen foliage, but the leaves are 

 spirally arranged and greyish green. 



The slender twigs show numerous scars of fallen 

 branches. They are glabrous arid striate and pass to 

 darker red-brown, purplish or grey-brown curved branches, 

 with lenticels. Buds showing very few scales. 



(/3) Twigs not covered with densely imbricated 

 scale-like leaves; with distinct internodes. 



* Buds on distinct stalks, lifting them out 

 of the leaf-axils. 



t Buds on pedicels as long as themselves or 

 longer. Bud-scales 2 3 of which one nearly 

 embraces the rest; glabrous and glaucous 

 or viscid ; leaf-scars angular shield-shaped, 

 or rhomboid with 3 5 leaf-traces. 



Alnus glutinosa, L. Alder (Figs. 106 and 34, 42). 

 Bud and shoot triangular in section. The buds rather 

 large, ovoid-distended, obtuse, turned slightly to one side 

 and somewhat triangular in section (Fig. 42) : there is 

 occasionally an accessory bud which remains dormant.
