442 Mr. Dow's Descriptions of Five new Species of Pinus. 
3. PINUS RADIATA. 
P. foliis ternis? strobilis ineequilateri-ovatis : squamis radiato-rimosis umbi- 
lico depresso truncatis; baseos externe tripló majoribus gibbosis sub- 
recurvis. 
Habitat in California, in maris littore ad Monterey. Coulter. h. (v.s.sp.) 
Arbor rectissima, altitudinem circiter 100 pedes attingens, ramis latè 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 tripló 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? strobilis inzequilateri-oblongis aggregatis : squamis apice quad- 
rangulis umbilico depresso truncatis; baseos externae majoribus elevatis 
conicis. 
Habitat in California, in maris littore ad Monterey. Coulter. h. (v.s. sp.) 
Arbor 100-pedalis. Sérobili oblongi, aggregati (3), fulvo-cinerei, 4-pollicares, 
2$ uncias crassitie adzequant: squamis cuneatis, apice dilatatis, quadran- 
gularibus, umbilico depresso truncatis, ad basin exteriorem majoribus 
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 bifariàm patentibus linearibus mucronatis planis subtüs ar-
