552 OX SEEDLINGS 



Leaves cauline, opposite and verticillate, arranged in whorls of 

 three, though in some plants they seem to be in pairs with the odd 

 one slightly higher, or have even a spiral arrangement, linear, acute, 

 sessile, exstipulate, glabrous, light green, one-nerved. 1 



In all the Junipers and Thujas the young plants have needle 

 leaves. In many species of the Cupressines the subsequent foliage 

 is flattened ; and in some the two tendencies are so nearly balanced 

 that even on the same branch some twigs bear acicular, some 

 flattened, leaves. The former seem to be especially developed on 

 the lower and inner branches. 



Cryptomeria japonica, Don. 



Primary root tapering downwards, somewhat flexuose, pointed, 

 colourless, unbranched in its early stage. 



Hypocotyl erect, terete, glabrous, pale green, slightly stained 

 with red at the base, 1-1-6 cm. above the soil. 



Cotyledons two to three, linear, obtuse, flat above and deep 

 glaucous-green, slightly convex beneath and paler, 6'5-8 mm. long, 

 1-5-2 mm. wide. Out of seventeen seedlings three had two coty- 

 ledons, twelve had three cotyledons, and two were not sufficiently 

 advanced to determine the number. 



Stem erect, ultimately woody ; primary internodes undeveloped ; 

 ultimate ones very short. 



Leaves simple, entire, cauline, spirally arranged on the stem and 

 close together, exstipulate, sessile, decurrent, linear-falcate, ascending 

 towards the apex of the branches, three- to four-angled with the 

 posterior or dorsal angle strongest and decurrent on the stem or 

 branch, glabrous, deep glaucous-green. 



Nos. 1-3. Following each other closely, often appearing ver- 

 ticillate and alternating with the cotyledons. 2 



Taxus baccata, L. (fig. 677). 



Primary root tapering, fleshy, colourless, giving off very few 

 lateral fibres in its early stages. 



1 Tubeuf, 1. c. p. 103, describes and figures (fig. 143), the seedling of Thujopsis 

 dolabrata, which resembles that of Thuja gigantea, but has broader, very blunt 

 cotyledons. The primary leaves are also shorter and broader. 



Biota orientalis, L c. p. 104 (fig. 144), has two much larger cotyledons, 

 2-2 -2-5 cm. long, 1-5-2 mm. wide, but is otherwise at first very similar. 



Vide Tubeuf, 1. c. p. 97, where is a figure of a seedling and also of a 

 two-year-old plant. The seeds are described on p. 32.
