which have become known to us hitherto, fall, according to 

 Endlicher, into two groups : 



a. The American group (Brazil and Chili) : A. brasiliensis 

 (Rich.), between 15 and 25 S. lat.; and A. imbricata 

 (Pavon), between 35 and 50 S. lat., the latter growing to 

 234260 English feet. 



b. The Australian group : A. bidwilli (Hook.) and A. 

 cunninghami (Ait.) on the east side of New Holland ; A. 

 excelsa on Norfolk Island, and A. cookii (E. Brown) in New 

 Caledonia. Corda, Presl. Goppert, and Endlicher, have 

 already discovered five species of Araucarias belonging to the 

 ancient world in the lias, in chalk, and in beds of lignite 

 (Endlicher, Coniferae fossiles, p. 301.) 



Pinus Douglasii (Sabine), in the valleys of the Eocky 

 Mountains and on the banks of the Columbia Eiver (north 

 lat. 43 52) . The meritorious Scotch botanist from whom 

 this tree is named perished in 1833 by a dreadful death in 

 collecting plants in the Sandwich Islands, where he had 

 arrived from New California. He fell inadvertently into a 

 pit in which a fierce bull belonging to the cattle which have 

 become wild had previously fallen, and was gored and 

 trampled to death. By exact measurement a stem of 

 Pinus Douglasii was 57 J English feet in girth at 3 feet 

 above the ground, and its height was 245 English feet. 

 (See Journal of the Eoyal Institution, 1826, p. 325.) 



Pinus trigona (Eafinesque), on the western declivity of the 

 Eocky Mountains, described in Lewis and Clarke's Travels 

 to the Source of the Missouri Eiver and across the American 

 Continent to the Pacific Ocean (18041806), 1814, p. 

 456. This gigantic Fir was measured with great care ; the
