440 Mr. Don's Descriptions of Five new Species of Pinus. 



new species of Pinus ; and I have to regret that the specimens of three of 

 them are without leaves, Dr. Coulter not having been able to find them, from 

 the want of a convenient opportunity to arrange his vast collections. The 

 cones of these, however, are so marked as to leave no doubt of their con- 

 stituting three very distinct species. 



1. Pinus Coulteri. 



P. foliis ternis prselongis compressis : vaginis filamentoso-laceris, strobilis ob- 

 longis solitariis maximis : squamis cuneatis ; apicibus elongatis incras- 

 satis lanceolatis mucronatis ancipiti-compressis aduncis. 



Habitat in California, in montibus Sanctse Luciee, alt. 3000 — 4000 ped. Coulter. 



h . (v. s. sp.) 



Arbor magna, robusta, altitudine 80- v. 100-pedalis, cortice spadiceo obducta, 

 ramis amplis, apice diffusis. Ramidi h squamarum stipularium basibus 

 callosis toruloso-tuberculati, crassitie pollicares. Folia terna, rar^ qua- 

 terna v. quina, dodrantalia, incurvata, compressluscula, mucronata, supr;\ 

 bisulca, subt^s planiuscula, margine lineaque media elevata tenuissime 

 serrulatis. Vagime sesquiunciales, crassitie pennae corvinse, basi tu- 

 midse : squamis ovato-lanceolatis, acuminatis, cartilagineis, spadiceis, ni- 

 tidis, adpressis, margine scariosis, albis, filamentoso-laceris ; in/erioribus 

 brevissimis, carinatis ; stipularibus majoribus, longiils acuminatis, basi 

 cucuUata callosa indurata persistenti. Strobili omnium maximi, conico- 

 oblongi, pedales et ultra, diametro ad medium semipedem adsequant, et 

 libras quatuor circiter pondere : squamis cuneatis, apicibus elongatis, lan- 

 ceolatis, mucronatis, ancipiti-compressis, obsolete quadrangulis, incur- 

 vato-aduncis, crassissimis, induratis, Isevibus, nitidis, spadiceis, margine 

 acutis, 1 — 3-uncialibus ; iiiferioribus longioribus, deflexo-patentibus. 



Discovered by Dr. Coulter on the mountains of Santa Lucia, near the Mis- 

 sion of San Antonio, in latitude 36°, within sight of the sea and at an elevation 

 of from 3000 to 4000 feet above its level. It was growing intermingled with 

 Pinus Lambertiana. The tree rises to the height of 80 or 100 feet, with large 

 permanent spreading branches, and the trunk is 3 or 4 feet in diameter. The 

 leaves are longer and broader than those of any other Pine, and the cones
