^ PoDOCARPUS MoTLEYi Diimmer (comb. nov.). In 1857-8 Mr. 

 James Motley collected specimens (No. 1300) of a Conifer near 

 Bangarmassing (spelt also Bangermasin or Bandgermasin) in 

 Southern Borneo, which he described as a large lofty tree with 

 smooth yew-like bark, bearing the native name, " Kaju saribu 

 dauni," meaning literally the " tree of a thousand leaves," in 

 reference doubtless to its densely leafy crown. Some of these 

 specimens fell into the hands of the celebrated Italian botanist 

 Parlatore, who described and named the species Dainmara 

 Motley i (without, however, seeing fertile material), in compliment 

 to its discoverer. 



Parlatore's original description occurs in his List of Seeds of 

 the Florence Botanical Gardens for 1862 (published 1863), and 

 synchronously, if not earlier in this Journal for Feb. 1863 (p. 36) : 

 Seemann [1. c.) in a footnote to Parlatore's description writes : 

 "The genus must be considered doubtful, as the fruit is unknown. 

 It may be a Podocarpus. Some time ago I asked the question in 

 the Gardeners' Chronicle, how the Nageia section of Podocarpus 

 could be distinguished from the genus Dammara in habit ; and since 

 then Mr. Charles Moore of Sydney has drawn my attention to 

 the fact that the Dammara is leafy, even after the branches are 

 several feet long, whilst in Podocarpiis it becomes bare at a very 

 early stage ; and, as far as I have been able to observe, this 

 distinction holds good." 



This difference is decidedly apparent in specimens under 

 cultivation : in the Temperate House at Kew the leaves are 

 known to persist on the trunks of the various species cultivated 

 there for 5-20 years ; moreover, another constant obvious vege- 

 tative character separating these two genera appears to lie in 

 the terminal buds ; which in Podocarpus are narrowed and 

 always pointed, while in Agathis {Dammara) they are without 

 exception broad and hemispheric or depressedly hemispheric. 



Messrs. Seward & Ford in their interesting account of the 

 Arancarieae, recent and extinct (Phil. Trans, cxcviii. 317 (1906)), 

 confirm Seemann's suspicions, having made an anatomical in- 

 vestigation of the leaves ; they say " the lamina, which is almost 

 isobilateral, is characterised by the occurrence of resin canals 

 between [below] the vascular bundles, and by numerous thick- 

 walled fibres, with hardly any lumen below the epidermis. In 

 this and other features the anatomy conforms to that of leaves of 

 Podocarpus Nageia." Prof. Seward in a letter adds that in 

 Podocarpus the resin canals of the leaves are below, in those of 

 Agathis between the veins. Taking these views therefore into 

 consideration, there can be but little doubt as to the correct status
