由国分类学文献中南洋杉属两种之订正

通过调查,对Araucaria cunninghamii和A.heterophylla的选模式和中国分类学文献(如<广州植物志>、<中国树木学>、<中国高等植物图鉴>、<中国植物志>、<中国树木志>、、<中国高等植物>)的A.cunninghamii和A.heterophylla(或A.excelsa)作比较,证实中国分类学文献中的A.cunninghamii和A.heterophylla(或A.excelsa)分别是A.heterophylla(Salisb.)Franco和A.cunninghamii Aiton ex A.Cunn..这两种植物的叶形变化较大,但有明显的区别:诺福克南洋杉A.heterophylla幼树的末级小枝的叶细长呈线形、叶尖急尖,牛长角小于45°,腹面无明显的脊,成龄株的末级小枝的叶扁平呈鳞片状;南洋杉A.cunninghamii幼树的末级小枝的叶呈两侧扁的钻形、叶尖短刺状,生长角45°-90°,腹背两面具明显的脊,成龄株的末级小枝的叶呈四棱状钻形.

Revision of two species of Araucaria (Araucariaceae) in Chinese taxonomic literature

Based on the lectotypes of Araucaria cunninghamii and A. heterophylla, the status of those species as cited in Chinese taxonomic literature, such as Flora of Guangzhou, Dendrology of China, Iconographia Cormo-phytorum Sinicorum, Flora Reipublicae Popularis Sinicae, Silva Sinica, Flora of China and Higher Plants of China, was reviewed. Araucaria heterophylla has linear, acute juvenile leaves held at an angle of less than 45° to the branchlet and without an obvious adaxial keel and scale-like adult leaves on terminal branchlets; A. cunning-hamii has bilaterally compressed, subulate, shortly pungent juvenile leaves held at an angle of 45°-90° and with an obvious keel on both surfaces and tetragonous, subulate adult leaves on terminal branchlets. The names A.cunninghamii and A. heterophylla have been misapplied in Chinese taxonomic literature and should be A. hetero-phylla (Salisb.) Franco and A . cunninghamii Aiton ex A. Cunn. respectively.
