Cockayne. — Development of Seedlings. 387 



Stipules interfoliar, adnate with petioles, triangular or 

 truncate, furnished with three very short deciduous red 

 glandular hairs at apex, ciliated, rather fleshy at first. 



The adult leaves differ considerably from those described 

 above, being narrow-lanceolate, extremely acute, long-petioled, 

 and furnished at regular intervals on both surfaces with stout, 

 acute, erect, white hairs ; midrib, margin of leaf, and petioles 

 deeply stained with reddish-brown purple. The seedlings 

 appear to vary very little. G. petriei grows in full sunshine, 

 closely pressed to the ground, forming a turf, on old stony 

 river-flats or on stony river-terraces where there is very little 

 earth and exposed to great heat in summer time, at altitudes 

 of from about 300 m. to 700 m., and covering large tracts of 

 ground. 



Coprosma areolata, Cheeseman. 



Seed gathered from plant at base of Signal Hill, Dunedin. 

 Sown seven months after gathering. Germinated in about 

 ten months. 



Description of Seedling. 



Eoot : Primary root straight, descending, very stout, with 

 numerous extremely slender filiform lateral rootlets. 



Hypocotyle 1cm. long, terete, tapering, dotted with 

 purple, glabrous. 



Cotyledons oblong, obtuse, dotted with minute scales on 

 under-surface, pale-green, sometimes later on becoming purple- 

 stained, 7 mm. X 3-5 mm. to 9 mm. x 4 mm.; petioles short; 

 midrib evident, pinkish ; margins entire, stained with light- 

 purple. 



1st pair of leaves : At first almost in same plane with 

 cotyledons, they become gradually raised by lengthening of 

 petioles, while at the same time the apex becomes more acute, 

 and points upwards; ]3mm. x 6mm., ovate, acute, entire, 

 with red margins and veins, ciliated on margin and midrib ; 

 upper surface pale apple-green ; under-surface paler than 

 upper ; veins much anastomosing ; midrib raised on under- 

 surface, especially towards petiole ; petiole semi- terete, chan- 

 nelled. 



Later leaves very similar to above, but larger ; base of 

 leaf tapering into and decurrent with upper part of petiole ; 

 upper surfaces, petioles, and margins hirsute with many long, 

 strict, acute, white hairs ; upper surfaces of leaves often 

 marked with purple blotches, as indicated in younger leaves 

 by pinkish-purple margins, &c., as described above. 



Stem at first very short ; cotyledons and 1st pair of leaves 

 appearing to emerge from same spot, gradually lengthening 

 as the 1st pair of leaves develope ; then erect, freely budding
