1/4 APPENDIX. 



The branches are slender and usually drooping, loaded with 

 small blue berries. Until recently considered as a form of 

 the eastern Virginia Juniper and may be better referred as 

 Juniperus Virginiana, variety scopulorum, N. var. 



Juniperus Knightii,* Avon Nelson. "A small tree or 

 large shrub usually branched from the base, with a rounded 

 bushy clump of sub-equal spreading branches 10-30 feet 

 high; branchlets stout and thick, leaves three-ranked; 

 berries large, blue-green or copper colored, scale vestiges 

 prominent, seeds single, rarely two, pulp dry. Usually the 

 sole occupants of dry desert regions of south-central and 

 southwestern Wyoming " (Nelson). Perhaps an aberrant 

 desert form of Juniperus monosperma Sargent, and may be 

 referred as J. monosperma, variety Knightii, N. var. 



Pinus peninsularis, spec, nov f This so-called 

 "marked variety " of the Jeifrey Pine is perhaps justly en- 

 titled to specific rank. It comprises a distinct forest, cloth- 

 ing the San Rafael Mountains southward to San Pedro 

 Martyr, and forming the axis of the long peninsula of 

 Lower California, at the altitude of about 4,000 feet in a 

 soil of newly-pulverized white sandstone. Trees 150-200 

 feet high, spire-formed or rounded in outline, bark grey, 

 very thick and hard, deeply fissured longitudinally, sap- 

 wood thin, white; leaves broad, 8-12 inches long, bud scales 

 and all the leaf bracts scarious and lasciniate, with large 

 white hairs. Yearling cones large, purple, oblong 1 inch 

 long; mature cones abundant, broadly ovate, 6-8 inches 

 long, truncate, basal undeveloped scales usually remaining
