a wild state of numerous hybrids. Only the leading types are 

 here described. 



* Leaves convolute ; catkins produced with the leaves ; -filaments 

 jree, hairy below; deciduous peduncle bearing leaves ; capsule 

 smooth. (Including the larger trees in the genus.) 



1. S. pentdndra (Bay-leaved Willow). — A shrub or tree, 6 — 20 

 feet high, with dark brown bark; handsome and fragrant, broad, 

 ovate, polished leaves, paler beneath ; stamens 5 ; stigma 2-fid. — 

 River-sides in the north ; frequent. The latest flowering Willow. 

 ■ — Fl. May, June. Perennial. 



2. S. tridndra (Almond-leaved, French or Brown Norfolk Wil- 

 low). — Naturally a tree 2c — 30 feet high, but cut down and treated 

 as an osier ; bark flaking ; leaves oblong-lanceolate, 2 — 4 in. long, 

 serrate, glabrous, paler beneath, with large stipules ; stamens 3. 

 — River-banks and osier-beds; frequent. — Fl. April, May. Pe- 

 rennial. 



3. S. jrdgilis (Crack Willow, Withy). — Growing into a large tree 

 with ascending, easily detached branches, but often treated as an 

 osier; very smooth, highly polished, yellow, orange, or crimson 

 bark; elliptic-lanceolate, serrate, glabrous leaves, 3 — 6 in. long, 

 pale beneath, hairy beneath, with semicordate stipules ; sta^nens 

 2; stigma 2-fid; capsule stalked. — Osier-beds; common. — Fl. 

 April, May. Perennial.

 not easily detached twigs ; lanceolate, acuminate leaves 2 — 4 in. 

 long, silky on both surfaces, with small, ovate stipules ; stamens 2 ; 

 stigma 2-fid, recurved ; capsule nearly sessile. The Golden Wil- 

 low {S. vitellina) is a form with bright yellow twigs, and the 

 variety ccerulea, the Cricket-bat Willow, is apparently a hybrid 

 between S. alba and S. frdgilis. — Wet places ; common, but often 

 planted. — Fl. April, May. Perennial. 



■^■^ Shrubs and small trees, mostly known as Sallows or Osiers ; 

 catkins sessile when in flower ; bracts on peduncle small or absent ;

 slender, tough twigs ; dark red or purple bark ; catkins appearing 

 before the leaves, with purple-black hairy scales ; leaves folded
