DWARF AND SLOW-GROWING CONIFERS 15 



stout acute apex; upper sides rather convex; decurrent 

 bases overlapping; branchlets horizontal or decurving. 

 Colour dull blue-green in summer, brown in winter. 



C. obtusa, var. Sanderi. — Leaves still shorter and 

 thicker; apex usually rounded and not acute; borne in 

 threes, ascending or at right angles; branchlets dispro- 

 portionately stout. Colour: in summer, glaucous eau 

 de Niel ; blue in winter — plum colour. Branchlets few 

 and ascending. 



C. pisifera, var. sqitarrosa. — Leaves very fine and small ; 

 borne in twos in opposite pairs — irregularly — ascending 

 at right angles or decurving; branchlets very fine and 

 crowded. Habit a dense upright pyramidal shrub. 

 Pale green in summer, slightly yellowish in winter. 



C. pisifera, var. ericoides and squarrosa pygmcea (''Arnold 

 Arboretum" variety) are of doubtful origin (see pp. 52 

 and 49). 



C. Lawsoniana, var. squarrosa (not in cultivation; 

 recorded in 1906 by Majrr as a juvenile form making a 

 light green pyramid with very fine small foliage). 



A form of uncertain origin was sent to me as var. 

 squarrosa nana aurea. Its leaves, which are very similar 

 to the first juvenile leaves of C. Lawsoniana, are borne in 

 threes, and occasionally in fours, irregular in direction, thin 

 and about \ inch long; colour light yellow-green. This is 

 not unlike reputed forms of C. pisifera and G. sphceroidea, 

 and I hesitate to identify it with C. Lawsoniana. 



Cryptomeria Japonica, var. elegans, will be found under 

 that species. 



These are the only juvenile forms of which I have found 

 records. The " intermediate forms " (which are more 

 distinct from each other) are : 



Cupressus Lawsoniana, var. Fletcher i. 



C. Lawsoniana, var. ericoides, 



C. pisifera, var. plumosa. 



C. sphceroidea, var. Andelyensis, 



C. obtusa, var, Kcteleeri.
