Luzupiaga marginata" {The Manjinatc LmitruKja). 



A pretty little plant, found chiefly in hilly diKtiicts. Leaves shining, Jin. 

 in len,t;th. Petioles twisted. Flower tcrmijial, white, Jin. long. Berry round. 

 Both islands. Fl. Dec. and Jan. (The plant appears under the synonym 

 Callixene parriflora in Hooker's Handbook and as Enargea marginata in 

 Cheeseman). 



Genus Goi'djjVnie. 



A genus found in New Zealand, Australia, and the Pacific Islands. The five 

 New Zealand species are all endemic. Herbs or trees. Leaves crowded, and 

 sword-like. Flowers regailar, Ijell-shaped, white. Stamens inserted on the

signifying a club). 5. sp. 



Cordijline belongs to the sub-family Draccenoicleae, and is 

 therefore related to the dragon-trees. Dragon's blood is the 

 resin which exudes from the bark of Draccena Draco. A very 

 famous specimen of this tree existed on the island of Teneriffe. 

 It was supposed to be about (5000 years old, but was 

 imfortunatelj' blown down in 1868. It was then 70 feet 

 high, and nearly 45 feet in girth. 



A peculiar secondary thickening of the stem takes place 

 in this sub-family. The primary arrangement of the bundles 

 of the stem is the same as in one of the palm-trees (v. 

 p. 'S'2) ; but after all the woody cylinders liave been originated 

 and are in course of development, a generating tissue appears in 

 certam regions of the stem r(.)und tire bundles, and grows 

 radially, thus giving rise to secondary wood. For a fuller 

 description of the processes of division and extension (.)f the 

 gr(jwing tissue, soine text book of anatomy should be con- 

 sulted. Tlie anatomy of the stem in the New Zealand species 

 of CorchjUne does not appear to l)e known at all fully, and 

 would prol;iably afford a profitaljle sul^ject of investigation. 



Diels makes a curious mistake with regard to C. auKtralis. 

 He is surprised to find tliat it has a xerophytic structure.
