Has a more upright growth than the species, with round- 

 ish cones, and a straight, distinct leading stem. It is 

 from the Tyrol, where it forms a small tree. 



Var. llliginosa, Wimmer. Syn. P. Fischeri, Booth. 

 " This is the Austrian form of P. Muylio, but very much 

 more robust in stature, forming a handsome pyramidal 

 small tree." 



Var, liana, London. KNEE PINE. London, in his 

 "Arboretum," places this as a variety of P.purnilio, and 

 describes it as follows: "The Knee Pine of the Styrian 

 Alps never grows above 3 feet high. A plant has been 

 in the Trinity College Botanic Garden, Dublin, since 1817, 

 and, in twenty years, it has not attained a greater height 

 than an ordinary-sized man's knee." 



11, P, muricata, D. Don. BISHOP'S PINE. Syn. P. 

 Murrayana, JBalfour. P. Edgariana, ffartweg. Leaves, 

 from 3 to 4 inches long, from a medium sized sheath, rigid, 

 stout, bright green color. Cones, 3 inches long, ovate, in 

 clusters, crowded, with thick, wedge-shaped scales, that 

 are mucronated, with an elevated umbilicus. Branches, 

 irregularly spreading, with small acute buds. Seeds, 

 small, dark brown.

 according to ISTuttall, was discovered by Dr. Coulter, at 

 San Luis Obispo, in latitude 35, and at an elevation of 

 3000 feet above the level of the sea, distant about ten 

 miles. The height is generally about 30 or 40 feet, and it 

 grows very straight, with a somewhat stunted appearance. 

 The strangest peculiarity about this species is in the 

 " squarrose spreading of the basilar scales, which present 

 long and sharp points in all directions." 



We are not aware of this tree having been tested in 

 this country, although it has proven hardy in England ; 

 but we cannot see anything to prevent it from succeeding 

 as satisfactorily with us, as many Conifers from the same 

 locality flourish here with perfect hardiness. It is true,
