CALIFORNIA BLACK WILLOW - Salix laevigata Bebb Salix congesta (Bebb) Howell. Salix Imvigata congesta Bebb This tree grows along streams and lakes from southern Oregon throughout Cali- fornia, extending eastward into Nevada and Utah. It sometimes becomes 15 or 16 meters high, with a trunk up to 6 dm. thick, but is commonly considerably smaller. The dark brown bark is thick and irregularly fissured; the young twigs are orange-brown and vary from smooth to densely velvety-hairy; the winter buds are ovoid, about 3 mm. long. The leaves vary greatly in form from nar- rowly lanceolate to oblong, oblanceolate or even obovate, and from finely and closely toothed to entire-margined, from long-pointed to obtuse, and from 6 to 20 cm. long, the largest being found on â strong, sterile shoots, as in other wil- lows; they are dark green, smooth, and shining on the upper side, pale or sometimes nearly white, and either smooth or hairy, on the under surface; their stalks are short, rarely more than 6 or 8 mm. long, and their ovate stip- ules are usually small, and fall away soon after they appear. The catkins, which are borne on short, leafy branch- lets of the season, flower from March to May, according to latitude, are from s to 10 cm. long, their axes and the toothed bracts very hairy; the staminate flowers usually have 5 sta- mens with filaments hairy toward the base, and the pistillate flowers have a smooth, ovoid-conic stalked ovary, the notched stigmas about ^as long as the short style. In fruit the pistillate catkins sometimes elongate considerably, but they are often short, sometimes not more than 4 cm. long; the smooth, ovoid-conic capsules are 4 to 6 mm. long, their slender stalks as long, or much shorter. The wood is soft, weak, brittle, light reddish brown, the sapwood near
