86 Transactions. — Botany. 



3rd internode grows considerably, until by the time that the 

 leaf is developed it almost equals the 2nd internode, now 

 4 mm. long. 



Seedling with cotyledons and three leaves (Plate YIII., 

 fig. 3). ' 



Stem flexuous, each internode being slightly bent from the 

 preceding in an opposite direction, but ascending upwards, 

 channelled, marked with a few scaly hairs, swollen at nodes. 



Leaves (so far as developed) very uniform, almost rotund, 

 patent, entire except for emarginate apex, glabrous, rather 

 dull-green; under surface more glaucous than upper, with 

 raised midrib. 



2nd leaf 11 mm. long x 6 mm. broad ; petiole 4 mm. long, 

 terete, articulated to lamina and to stem. 



Stipules triangular, opposite, usually reddish with pale 

 membranous margms. 



The largest of the plants examined had a stout branch 

 coming from the axil of each cotyledon, also a still shorter 

 branch from the axil of the 1st leaf. The leaves on these and 

 tbeir development were similar to what has been described 

 above. 



Kirk {I.e., p. 117) describes the leaves on seedling plant 

 thus : " 1-foliolate, obovate, emarginate, jointed to the pe- 

 tiole." The term " obovate" will certainly not apply to fully 

 developed leaves, though it would suit well enough an inuna- 

 ture leaf (see 3rd leaf in fig. 3). The South Nelson plant 

 grows on grassy fiats by the Mason Eiver, in full sunshine, and 

 also on the slopes of the Whale's Back in similar situations to 

 ordinary tall-growing leafless Carmichaelias , in the full sun- 

 shine. The mature plant is quite leafless, and the branches 

 are stifi', slender, and terete. Mr. S. D. Barker has plants 

 from all the localities mentioned in the Students' Flora grow- 

 ing in his garden. The Mount Peel and Mason Eiver plants 

 look very similar, but the Waikare plant might very well be a 

 different species. Its stem is flat, not terete. Under the 

 stimulus of spring its young growth consists of reversion 

 shoots, with flat stems and ternate small leaves, reduced 

 sometimes to a single narrower leaflet (see fig. 3\ Plate VIII.)''' 



Convolvulus erubescens, Sims. 



Seedlings grown by Mr. S. D. Barker from seed collected 

 from cultivated plant in his garden, originally from the Port 

 Plills. Germination very rapid {Barker). 



* Since writing the above description I have had an opportunity of 

 further examining Mr. Barker's seedlings. The largest is 87 cm. tall, 

 with ten branches, but still with entire leaves and quite terete, showing 

 no sign of any such development as exhibited by the Waikare plant.
