growths close to the main stem, clothed with lovely glaucous 

 foliage. A choice variety. C. L. Youngi is of quick growth 

 and erect habit; the ascending branches are long and, towards 

 the ends, droop gracefully ; the leaves as well as the shoots are 

 deep green. 



C. MacNabiana (C. glandulosa) rises to a height of about 

 12 ft. ; it is a much-branched compact tree, of pyramidal habit, 

 with short glaucous leaves, and is rather rare. 



To Mr. Hartweg belongs the credit of having discovered the 

 elegant G. macrocarpa (Monterey Cypress) (Fig. 314) in 

 Upper California, while collecting for • the Royal Horticultural 

 Society, upwards of fifty years ago. It is a beautiful tree, vigorous 

 and free in growth, with ascending branches and very distinct 

 foliage of the brightest green. The light brown cones are about 

 2in. long, and borne in small clusters. It grows about 50ft. high, 

 and is a valuable species for the park, especially in the South 

 and West of England. It flourishes amazingly by the sea-coast. 

 C. m. fastigiata differs from the type on account of its branches 

 being more upright and closer to the main stem. C. m. Crippsii 

 is an attractive and distinct variegated variety. It is free in 

 growth and quite hardy. The golden-leaved variety (luted) is 

 one of the most promising of recently-introduced Conifers. It 

 originated a few years ago in a bed of seedlings of C. macrocarpa 

 in the nurseries of Messrs. Dicksons, Chester. It is of about 

 equal hardiness to, and of the same habit as the type, and the 

 golden-coloured leafage is happily permanent. For growing in pots 

 or tubs for winter decoration as well as for winter bedding, this 

 charming variety should meet with a large demand. It is a 

 grand seaside tree. 



C. nootkatensis (Thuya nootkatensis, Thuyopsis borealis), the 

 well-known Nootka Sound Cypress, is a very graceful kind, 

 and suitable for all sorts of decorative planting. Besides being 

 one of the hardiest, it is perhaps the least exacting of the Cypress 

 family, and is vigorous and of elegant habit, with drooping branch- 

 lets. It is a native of British Columbia, and was discovered by 

 Mr. Menzies nearly a century ago, but does not seem to have 

 been grown in England until fifty years ago. C. n. albo- 

 variegata, though not so vigorous, is more compact than the 

 type. Its terminal branchlets and leaves are variegated with 

 creamy-white. C. n. aurea variegata is a yellow counterpart of 

 the last-named, and should have an open spot, as the variega- 

 tion is apt to fade when overshadowed by other trees. C. n. 

 compacta is a pretty form, of dense growth, and useful for small 

 gardens. It is very distinct. C. n. glauca is a beautiful variety 

 with glaucous leaves, which have a very pleasing effect, especially 

 after a shower of rain. It is a charming sort for small gardens, 

 and valuable also for ornamental planting. C. n. gracilis is 

 another elegant sort, of rather dense, free growth, with slender,
