specimen succeeds without protection as far north as New 

 York, it cannot be considered as hardy north of Washington. 



CUNNINGHAMIA si^ENSis, K. Brown. Lance-Leaved 



Pine. 



This is another genus of oaly one species. A small tree, 

 growing from thirty to forty feet high in Southern China, 

 where it often covers the sides of the mountains, forming 

 almost impenetrable thickets. Its leaves are from one to two 

 inches long, flat and thin, tapering to a point. Cones an inch 

 to an inch and a half long, oval, and mostly in clusters. Scales 

 very small, and almost obscure, forming merely a ridge, adher- 

 ing to a large, prominent, triangular bract. A very common, 

 low-spreading shrub in nurseries and pleasure grounds, but sel- 

 dom seen in good form or large enough to be classed among 

 trees. Probably a little more hardy than the Auricarids, which 

 it resembles, but I cannot recommend it for planting out in ex- 

 posed situations in any of our Northern States. 



SCIADOPITYS VERTICILLATA,, Siebold and Zuccarini. 

 Umbrella Pine. 



A very curious and remarkable conifer, from Mount Koja- 

 san, in the Island of Nippon, Japan, where it forms a large 

 spreading tree, a hundred feet high. Introduced into England 

 in 1861, and a few years later into this country. The leaves are 

 from three to four inches long, and about one-eighth broad, 

 double-ribbed, leathery, and blunt-pointed ; dark-green, and 

 crowded in whorls of thirty to forty at the joints or nodes of 

 the branchlets. Cones about three inches long, and an inch 

 and a half in diameter, solitary, with wedge-shaped corrugated, 

 persistent scales. This curious and unique conifer gives prom- 

 ise of being quite hardy in our Northern States, but so few have 

 as yet been tested in exposed situations, that a decision on this 

 point might be considered as premature. It is a rather slow- 

 growing tree while young, but may improve with age.
