 ,The' Victorian Naturalist\ December 1887.) 



Among the plants of striking interest, observed by Messrs. Cuth- 

 bertson and Sayer duriiig their ascent of Mount Obree, one of the 

 foremost is the coniferous tall tree, occupying rocky declivities at ele- 

 vations from 6000 feet upwards. The careful examination of a fruit- 

 bearing branchlet reveals the identity of this ^Pine" with the Arau- 

 caria Cunninghajui of tropical and suh-tropical eastern Australia, so 

 well known here also as one of the noblest of our park- and garden- 

 trees. Dr. Beccari, when ascending Mount Arfak in Dutch New 

 Guinea, came across the sanie Araucaria, which he likewise pronounced 

 in 1877 as not distinct froni A. Cunninghami ; but he noticed it at 

 heights from about 3000 to 4000 feet , though the Italian explorer 

 reached an altitude of fuUy 6000 feet. The occurrencc of this Arau- 

 caria, on mountains so very widely apart in the great Papuan Island, 

 seems to indicate, that much of the highland-country there is likely 

 occupied by this Pine, which fact,— if it could be established, — would 

 be of geologic significance and otherwise , also be of physiographic 

 importance. Pro£ David Don, so long ago as 1838 (Transact.Linn. 

 Soc. of London XVIII, 164) considered it not improbable, „that the 

 inferior of New Guinea niight afford a species of Araucaria", an anti- 

 cipation now so extensively realised. Mr. Sayer found the branchlets 

 less vaguely spreading and more distichous. than in the ordinary state 

 of this tree in Australia. The Araucaria Balansae from New Caledonia 

 is closely akin to A. Cunninghami , as characterised in Australia and 

 New Guinea ; but the seed-bearing rhacheoles are more circular in 

 outline, their terminal portion extending fully across to the lateral 

 membranous expansions, and ending in a less recurved spinular appen- 

 dage. Here it may aptly further be noted, that Araucaria Rulei be- 

 came first described in Lindley's Gardeners' Chronicle , for 1861, 

 when also of the typical form a Xylographie illustration was furnished 

 already. The staminate and pistillate rhacheoles of Coniferae are in 

 every respect coraparable to those of Cycadeae. Finally it may be 

 mentioned , that the length of the spinular appendage of the seed- 

 bearing rhacheoles in Araucaria Cunninghami is subject to considerable 

 Variation.
