Notes on the Arboreous, Arborescent and Supfruticose Flora of Oregon 

 (concluded).— i^'/v/.riHMS Oregana, Nutt. Along streams and lowlands, attains -} feet in 

 diameter, o-enerally smaller, low and scrubby, very little clear lumber to be had from 

 the best trunks. It is used chiefly for fuel and is estimated for this purpose to Ijc 

 nearly double the value of either of the species of Abiea, and brings about twice as 

 much per cord in the market. As fuel its value is about equal to that of the oak, and 

 very large quantities are now used in the country and the supply must soon become 

 exhausted near the cities. 



Celtis reticulata, Torr. A shrub of straggling growth,- 6 feet high at the Dalles of the 

 Columbia, fruiting al)undantly, fruit dark brown when ripe. 



Querruf Douglnsii. Hook. This is the onlj^ species observed on the Williamette or 

 Columbia rivers. It disappears near the coast and does not reach far into the Cascades. 

 It seems coulined to tne hilly regions of valleys and attains 2 and 3 feet in diameter, 

 rarely 4 feet, but is low and scrubby. Some trees will afford a 12 foot stick compara- 

 tively free from knots. The branches are wide spreading and drooping, often coming 

 so near the ground that they can be reached with the hand. Phomdendron flacescens, 

 var. ;)M/je«ce/?-« grows upon this tree exclusively and is not rare on the lower drooping 

 limbs. It is the hard-wood tree of the carriage maker and is extensively used in the 

 manufacture of heavy wagons, but all light carriage material is brought from the East- 

 ern States. 



Castampsis chrpsojiht/Ua, A. DC. A branching shrub, 4 feet high in the Cascade 

 hiountains, with fruit resembling the chestnut. 



Corylus rostrata. Ait., var. Californica, A. DC. The shrub of the usual size has 

 rounder, not pointed leaves and the beak of the fruit quite short, the upper as well as 

 the lower surface of the leaves pubescent, serratures much finer. Along streams, rather 

 rare. 



Myrica (Mifoniica, Cham, ife Schlecht. Sandy hills on the coast. A shrub 4 to 10 

 feet high with lanceolate, toothed leaves. 



Betula piimila, L. A shrub 3 to 4 feet high, in ponds. 



Alihus Orega/ui, Nutt. (,1. /•(f/)?v^ Bongard). A medium sized tree on stream banks 

 in the valleys, the largest attaining 3 feet in diameter and 40 to GO feet in height. 

 Mostly scrubby and very little clear lumber can be made from the best trunks. 



Salix longlfoUa, Muhl. On the Williamette River, 6 to 8 feel high. 



Salix lanceolata, Anderson. A tree afoot in diameter, 30 feet high, with lanceolate, 

 long pointed, smooth, finely serrated leaves, on banks of streams. 



Salix rhrysophyWi, var. pellita, Anderson-. Wet Alpine woods in the Cascades. A 

 low shrub. 



Salir SifrJi.<m.u,s, Bongard. A large shrub with silvery silky U'aves, very pretty. 



Salix sesxilifplia, var. nillona, Nutt. A shrub on the Williamette River, 4 to G feet 

 high, with whitish villous leaves. 



Some other undetermined species occur. 



Pojmliis halsdmifem, L. This is the common poplar of this State, attaining 4 feet 

 in diameter, generally 2 to 3. It grows frequently symmetrical and rather tall and 

 often affords logs for clear lum1)er. It abounds on the streams and lowlands in the val - 

 leys, and though common it is not abundant. It is used to some extent for lumber.
