428 WILSON EXPEDITION TO CHINA 
carpium corneum, ab exocarpio solutum; semina oblongo-ovoidea, 
testa ossea, atrobrunnea, nitida, basi hilo albido transverso exsculpto 
notata; albumen tenue; embryo rectus, cotyledonibus foliaceis amplis 
margine sigmoideo-recurvis basi subcordatis, radicula brevi ad hilum 
spectante. — Frutex stellato-pubescens foliis deciduis serratis petio- 
latis, stipulis parvis deciduis, floribus coetaneis in racemos terminales 
dispositis breviter pedicellatis parvis bracteis bracteolisque parvis 
caducis institutis, capsula pedicello incrassato insidente, ovoidea, 
apice basibus stylorum persistentibus coronata, lenticellata. 
Genus novum Sinowilsoniae et Corylopsi affine: a priori cui habitu 
et foliis simillimum praecipue calycis tubo turbinato quam ovarium 
breviori, petalis subulatis, cotyledonibus amplioribus margine recurvis 
bene distincta; a posteriori cui florum structura arctius affine, defectu 
disci, petalis minutis, antheris sessilibus, capsula apice attenuata nec 
truncata, lenticellata, cotyledonibus amplis margine recurvis, foliorum 
indumento, forma, nervatione valde differt. 
Species unica Chinae centralis incola. 
This new Chinese genus is named for the late Robert Fortune whose travels 
in China and Japan, from 1843-1861 resulted in important additions to our knowl- 
edge of the far eastern, and particularly the Chinese flora and enriched our garden 
with a large number of highly ornamental plants. Lindley in 1846 (in Jour. Hort. 
Soc. I. 150) named a Chinese plant Fortunaea chinensis, but the same plant had 
been previously described by Siebold & Zuccarini as Platycarya strobilacea. 
Fortunearia closely resembles in foliage and habit Sinowilsonia, which differs 
chiefly in its tubular calyx-tube several times longer than the ovary and en- 
closing it, by the absence of petals, the larger spatulate sepals, sessile flowers 
and the flat cotyledons. In the structure of its flowers it seems most closely re- 
lated to Corylopsis, which ,however, is easily distinguished by the presence of a 
disk, large petals, stamens with long filaments, truncate, not lenticellate capsules, 
flat cotyledons and by the nervation, shape and pubescence of the leaves. 
In some specimens collected in autumn we find terminal on short branchlets 
a few peculiar naked oblong aments, only 5-6 mm. long and resembling short 
staminate catkins of Corylus. The flowers of these aments contain in this stage 
well-developed anthers and in the centre a rudimentary ovary consisting of a two- 
pointed body only about one-third as long as the stamens; whether this rudimen- 
tary ovary will develop into a normal pistil the following spring or will remain 
rudimentary, cannot now be determined. In the latter case Fortunearia would 
turn out to be an andromoncecious genus like Sinowilsonia, but neither in this 
genus nor in Distylium have similar naked autumnal aments been described and 
we have searched in vain numerous specimens of these two genera for such aments. 
For the solution of the question regarding the character of these aments we 
probably have to wait until the plants now growing in the Arnold Arboretum and 
in other gardens flower.
