Species of Styrax in Herb. Léveillé. 
BY 
WILLIAM: WRIGHT SMITH, M.A. 
THE following uotes are in the nature of a supplement to the 
preceding paper on the Asiatic Styracaceae. They give the 
results of a survey of the species of Styrax described or recorded 
from China by the late Monseigneur Léveillé. The meagreness 
of the material on which Léveillé founded many of his species 
and the correspondingly inadequate descriptions render it 
difficult for any hi tanist to appraise the validity or sometimes 
even to recognise the affinity of the species concerned. The 
possession of tiie types makes a review of his species possible, 
but many of these must still be classed among the “‘ imperfectly 
known.” Of his species of Styrax there are one or two which 
I can neither relegate to a previously known species nor confirm 
the validity of. In his floras of Kweichow and of Yunnan 
Léveillé has recorded various species of Styrax. In so far as 
these are represented in his collection I have given an opinion 
.as to the correctness or otherwise of the record. One species I 
have failed to trace—Styrax Esquirolii, Lévl. in Fedde, Repert., 
ix (1911), 446. It is not in his herbarium. In his Flore du 
Kouy-Tchéou this species is omitted from the key and from 
the list of his species of Styrax, perhaps by accident or possibly 
by design. The double omission suggests that the specimen 
may have been lost—it is No. 22 Esquirol, one of that collector’s 
earliest specimens—or the validity of the species perhaps became 
a matter of doubt to the author. If Esquirol’s number is not 
in any other herbarium the species is fated to remain a dubious 
quantity. 
The following is the list of the named species of Styrax in 
Léveillé’s herbarium. I have appended my comments on each 
species. I have failed to come to any definite decision regarding 
S. Argyi, Lévl. and S. Cavalerie?, Lévl. 
1. §. Argyi, Lévl. in Fedde, Repert., xi (1912), 64. Type. 
Province of Kiangsu. Coll. d’Argy 
There are no details of locality or date. Material consists 
of twigs with fruits and of twigs with flowers in bud only.
