OF TAXODIUM DISTICHUM AND RELATED SPECIES 399 
with a single species, which has possibly never been brought to 
the United States, and which would not be hardy in this part of 
the country” [Massachusetts]. ‘It is a comparatively small tree 
in its native swamps, and, in spite of its southern home, is hardy 
in New England, where it is one of the most distinct and beautiful 
of the pyramidal conifers. The proper name for this tree is 
Taxodium distichum, var. imbricarium.” 
In front of the main building of the Department of Agricul- 
ture in Washington there are two trees of this species one labeled 
‘Chinese Water Pine, Glypiostrobus pendulus, China,” and the other 
the same except that it is called G. Sinensis. Scattered about the 
parks of the city are many similar specimens, as well as some of 
Laxodium distichum. Although they are rather pyramidal in shape, 
unlike Zaxodium imbricarium in its native habitat, they have the 
appressed leaves and erect branchlets of that species, and seem to 
differ only in their peculiar shape, which is probably only the result 
of long cultivation under unnatural conditions. The only speci- 
men of “ Glyptostrobus pendulus”’ in the Columbia University Her- 
barium is from a tree cultivated in Philadelphia, and on the back of 
the sheet is written a note to the effect that it came from a seedling 
of Taxodium distichum. 
In the Gardener’s Chronicle (III. 26: 489. 7. 761) for De- 
cember 30, 1899, there is a figure of one of these cultivated 
Specimens growing in England, and it is there contrasted with 
Glyptostrobus heterophyllus, its identity with G. pendulus evidently 
being taken for granted. 
The question might now arise: Are there really two species of 
Glyptostrobus in Asia? Apparently not ; for no flora of China or 
Japan to which I have had access contains any reference to G, 
Pendulus, and it is most likely that Endlicher described this spe- 
cies from a cultivated specimen, and erred in crediting it to China. 
A number of horticultural names which have been given to this 
cultivated plant may be found in Sargent’s Sylva, among the 
Synonyms of Zaxodium imbricarium.
