442 Mr. Don's Descriptions of Five new Species of P'mus. 



3. PiNUS RADIATA. 



P. foliis ternis ? strobilis inaequilateri-ovatis : squamis radiato-rimosis umbi- 

 lico depresso truncatis ; baseos externse tripl6 niajoribus gibbosis sub- 

 recurvis. 



Habitat in California, in maris littore ad Monterey. Coulter, h . (v. s. sp.) 



Arbor rectissinia, altitudinem circiter 100 pedes attingens, ramis latfe patenti- 

 bus copiosis ad basin usque ornata. Strobili aggregati, ovati, 6-pollicares, 

 basi exteriore ventricosi ; squamis cuneatis, crassis, spadiceis, nitidis, 

 apice dilatatis, depressis, quadrangulis, radiato-rimosis, umbilico de- 

 presso ; ad basin exteriorem tripl6 majoribus, apicibus elevatis, gibbosis, 

 subrecurvis. 



Found by Dr. Coulter about Monterey in latitude 36°, near the level of the 

 sea, and growing almost close to the beach. The trees grow singly together, 

 and reach the height of 100 feet, with a straight trunk, feathered with branches 

 almost to the ground. It affords excellent timber, which is very tough, and 

 admirably adapted for building boats, for which purpose it is much used. 



4. PiNUS TUBERCULATA. 



p. foliis ternis r strobilis insequllateri-oblongis aggregatis : squamis apice quad- 

 rangulis umbilico depresso truncatis ; baseos externae niajoribus elevatis 

 conicis. 



Habitat in California, in maris littore ad Monterey. Coulter . b . (v. s. sp.) 



Arbor lOO-pedalis. Strobili oblongi, aggregati (3), fulvo-cinerei, 4-pollicares, 

 2\ uncias crassitie adsequant : squamis cuneatis, apice dilatatis, quadran- 

 gularibus, uuibilico depresso truncatis, ad basin exteriorem niajoribus 

 apice elevatis, conicis. 



Found by Dr. Coulter along with the preceding, which it resembles in size 

 and habit, but is essentially distinguished by the form of its cones. 



5. PiNUS BRACTEATA. 



p. foliis solitariis bifarikm patentibus linearibus mucronatis planis subtCis ar-
