396 Transactions. — Botany. 



Cotyledons 5 mm. x 2-75 mm., linear-oblong, obtuse, ses- 

 sile, unequal in size, thick, coriaceous, glabrous. 



Leaves imbricatmg, with broad sheathing bases, matted 

 together at base with long cobwebby white hairs. 



3rd leaf: Lamina narrow-oblong, 5 mm. x 3-5 mm., one 

 tooth on one side, rest of margin entire, obtuse, varnished 

 green on upper surface, paler on under-surface, tapering into 

 the long petiole ; petiole 5 mm. long, broader at base, sheath- 

 ing and imbricating with other petioles. 



Next few leaves very similar. 



Further development not yet observed. 



It is only the extreme difficulty of raising such a Celniisia 

 as this from seed, and the further difficulty of keeping the 

 seedlings ahve when raised, that decided me to give the above 

 meagre description. 



Veronica armstrongii, Hook. f. 



The seedling plant referred to in Part I., and of which a 

 photograph is appended (Plates XXVIII. and XXIX.), was, 

 for purpose of photographing, taken out of its small pot, and 

 then repotted in a larger one, in the middle of October, 1898. 

 The plant was kept until the middle of December in the 

 greenhouse, along with the other seedlings, by which time 

 the tips of the shoots in nearly every instance were beginning 

 to approach nearer to the adult scaly adpressed form. The 

 plant was then placed under a bell-glass and kept very moist, 

 to see if under such conditions it would again revert to the 

 seedling form. The experiment has been eminently success- 

 ful, and now — February, 1899 — every shoot is well furnished 

 at the tip with seedling leaves, which are 4 mm. long, petio- 

 late, linear-lanceolate, deeply toothed, with two opposite teeth 

 on each side, one tooth or the older leaves entire, bright-green, 

 soft and succulent ; petioles broad, connate ; midrib evident. 

 The smaller more - reduced leaves further down the stem 

 have also opened out considerably, and their upper portion 

 is quite patent. The plant is in good health, and growing 

 vigorously. The shoots are leafy and green for their whole 

 length, and the plant in its present state much more resembles 

 V. loganioides, Armstg., than its own adult form. I am going 

 to keep it under the same conditions, to see if it is not pos- 

 sible to bloom it while in this still juvenile form. The plant 

 is now 13-6 cm. tall and 10 cm. in diameter, with branches 

 opposite and quadrifarious.
