A small tree with deciduous foliage and branchlets like Taxodium. 

 Leaves of two forms : on the ordinary branchlets spreading, ar- 

 ranged in three rows, acicular, decurrent, I to | inch long ; on 

 fruiting branchlets closely imbricated, scale-like, concave internally, 

 and keeled externally. 



Cones pear-shaped, about inch long, formed of numerous 

 elongated scales, each of which is 5- to 7-lobed at the summit, 

 and coalesced below with the bract, the tip of the latter project- 

 ing as a recurved point from the middle of the scale. Seeds two 

 on each scale, oblong, compressed, prolonged at the base into a 

 flattened lancet-shaped wing. 



ftyptotfrobu heterophyllm is a native of the province of Canton 

 in Southern China where it occurs along the banks of rivers and 

 streams. It first became known to science through Lord Macart- 

 ney's mission in China (1792-1795) ; and is supposed to have been 

 introduced in 1804 to Kew, where there is a specimen in the Tem- 

 perate House. 



The genus Gli/ptostrobus is allied to Taxodivm but differs in 

 the structure of the cone-scale and seed. The photograph repre- 

 sents a native specimen.
