Species novae ex ,Hookers Icones Plantarum“, 265 
sepalis cochleari-spathulatis, et staminodiis 5 sepalis oppositis differt; a 
posteriore floribus unisexualibus (dioicis?), florum femineorum receptaculo 
tubuloso-ventricoso et petalis deficientibus recedit. 
Flores unisexuales, feminei tantum visi. Receptaculum (calycis 
tubus sensu auctorum nonnullorum) urceolatum vel tubuloso-ventricosum, 
ovarium multo superans. Sepala 5, receptaculi ori affixa, cochleari-spathu- 
lata, breviter unguiculata. Petala nulla. Staminodia 5, staminiformia, 
mucronata, sepalis opposita et iis dimidio breviora. Ovarium fere liberum, 
` 2-loculare ; styli liberi, exserti, sepala excedentes; ovula in loculis soli- 
taria, ab apice loculorum pendula. Capsula lignescens, sessilis, basi 
lata, ovoidea, receptaculo supra medium arcte vestita, 2-locularis, 2-sperma, 
ultra medium loculieide dehiscens, bivalvis; endocarpium corneum, ab 
exocarpio solutum. Semina oblonga; testa dura, nitida, laevis, basi hilo 
transverso notata; albumen tenuissimum; embryo rectus, axilis, albumen 
fere aequilongus; cotyledones planae, amplae; radicula brevissima.

branacea, alterna, breviter petiolata, late obovata, elliptica vel fere orbi- 
cularia, 10—18 cm longa, 6—11 cm lata, acuminata, acuta, basi rotundata 
vel obscure cordato-lobata, supra demum glabrescentia; venae primariae 
laterales utrinque 7—9, arcuatae, ut secundariae et tertiariae per totum 
ambitum in dentes callosos excurrentes. Stipulae lineares, circiter 8 mm 
longae, citissimo deciduae. Flores masculini ignoti; feminei inconspicui, 
in spicas terminales simplices breviter pedunculatas cum pedunculo 
10—12 cm longas dispositi, numerosi. Receptaculum circiter 6 mm 
longum, 3 mm latum, extus pilis stellatis multiradiatis, intus pilis longis 
rectis sericeis dense vestitum. Sepala 1 mm longa. Staminodia 5 mm 
longa. Styli filiformes, quam sepala dimidio longiores. Spicae fructi- 
ferae 15 —20 cm longae. Capsulae basi lata affixae, circiter 8 mm longae, 
receptaculo persistente dense stellato-pubescente, semi inclusae; epicar- 
pium dense strigosum.

The investigation of this interesting new genus has involved the 
examination of several allied genera, more especially Distylium S. et Z. 
and Sycopsis D. Oliv., including a number of unpublished species, and 
the results are so important as to call for further illustration and des- 
cription. We have now sufficient material of both of the genera named 
to admit of the completion of their definitions; this will be done in the 
next part of the Icones Plantarum. It is certain that the flowers of 
Distylium are not polygamous, and that the male flowers of Sycopsis are 
more highly organised than was supposed. The genus Sinowilsonia is 
named in compliment to Mr. E. H. Wilson, whose excellent collections 
have thrown light on many doubtful points conected with Chinese plants.
