Cockayne. — Development of Seedlings. 367 



Stipules triangular, lacerate or bristly at apex, adnate, 

 embracing base of petiole. 



In its natural habitat G. gracilis is a plant with long 

 straggly usually quite leafless stems, spreading and becoming 

 entangled in the neighbouring vegetation and itself, after the 

 manner of some of the New Zealand forms of Buhus and 

 M%Menbechia, which in habit it much resembles, such being 

 very different indeed from that of typical species of Car- 

 77iich(slia. Where the stems are sheltered adult leaves are 

 developed as described above. Cultivated in a moist green- 

 house a plant rapidly developed shoots not unlike the juvenile 

 form, but when this same plant was removed to a very dry 

 situation in my garden the new stems that were produced 

 were almost leafless. The seedling form puts one in mind 

 of C. exsul, of Lord Howe Island (vide fig. 4a, page 266, 

 in Diels's work*) and it looks far more adapted for a moist 

 forest region than for a lowland swamp liable to drought in 

 summer.

 and 13 [Corallospartium , Armstg.). 



Seed collected at Mount Torlesse, from plants growing on 

 stony hillside below the winter snow-line, in dry clayey soil, 

 and exposed to wind and sun. Germinated in about four 

 weeks. The seed was quite soft when gathered. 



Description of Seedlings. 



(The most developed of the seedlings were grown by Pro- 

 fessor A. Dendy, D.Sc, and kindly given me for this work.) 



Eoot long, deeply descending ; lateral rootlets few, short. 



Cotyledons 6 mm. x 4 mm., unsymmetrically oblong, some- 

 times falcate, obtuse, fleshy, entire, with faint-red margin, 

 glabrous, darker green on upper than on under surface ; 

 petioles connate at their base, semi-terete, channelled above, 

 pointing upwards and outwards ; lamina with surface quite 

 horizontal. 



Stem notched at nodes ; 1st internode variable in length, 

 3-5 mm. to 5-5 mm., almost terete at base, slightly angled, 

 dotted with minute scales in young plant 1*9 cm. high, and 

 hairy with long matted white hairs in plant 4-3 cm. high ; 2nd 

 internode in the younger plant almost glabrous and more 

 deeply grooved than 1st internode, in the older plant similar 

 to 1st internode ; 3rd internode hairy, as described for older 

 plant. In the older plant the stem is much thicker than in 

 the younger, purplish-brown, with very deep furrows and 

 prominent longitudinal ridges marked with one or two longi-
