384 Transactions. — Botany. 



1st pair of leaves fleshy, tender, rotund, rotund-ovate or 

 ovate, obtuse; midrib sunken above, hardly evident beneath; 

 lamina 6 mm. x 5 mm., minutely ciliated, and with a few 

 white scales on the surface ; petioles 3 mm. long, subterete, 

 slightly channelled, connate at base. 



2nd pair of leaves obovate, entire or lobed, more distinctly 

 ciliated ; lamina tapering into petiole, otherwise as first 

 leaves. 



3rd pair of leaves similar, but larger, and margin crenate 

 above middle of leaf. 



Further development of leaves : The later leaves (Plate 

 XXXIII., figs. 36, 40, 41) become almost sessile, with white 

 midrib above, less distinct beneath, with margin crenate 

 above centre, with shallow lobe at apex, and with base sub- 

 cuneate. These leaves are followed by larger leaves less 

 cuneate at base ; these by almost oval sessile leaves, still 

 crenate on upper half of sometimes red-stained margin ; and 

 later on still subacute obovate leaves appear. 



Stem at first erect, then apex inclines downwards and 

 horizontal branches are developed from the early nodes, 

 terete, at first pinkish, afterwards pale-green, hoary with grey 

 pubescence ; internodes (in plant 8 cm. high) 4-5 mm. long. 



The development as described above does not as yet show 

 the change into the very distinct adult form (Plate XXXIII., 

 fig. 42). 



Veronica diosmsefolia, E. Cunn. Plate XXXII. , fig. 26. 



Seed gathered from cultivated plant in garden of Mr. W. 

 Martin, Fairfield, Dunedin. Germinated rapidly, and plants 

 are of extremely fast growth. 



Description of Seedling. 



Eoot long, wiry, and with numerous long lateral rootlets, 

 especially from base. 



Hypocotyle very short, 2 mm. or 3 mm. long, finally very 

 stout and woody. 



Cotyledons oblong, entire, slightly eraarginate, succulent, 

 pale-green, very short petioled ; petioles connate at base. 



1st to 3rd pairs of leaves lanceolate, upper half of margin 

 deeply toothed; acute, sometimes dotted on both surfaces with 

 minute white scales, tapering into the petiole ; petiole sub- 

 terete, channelled above, one-quarter length of lamina ; lamina 

 6mm. X 3'5mm. 



4th or 5th pairs of leaves and upwards most uniform in 

 shape, linear- or very narrow linear-lanceolate, almost sessile, 

 convex on upper surface owing to infolding of sides of lamina; 

 midrib evident on upper and under surfaces ; margins serrate
