A~tmct：Having different characteristics of branchlets，leaves and perianth，Elaeocarpus hayatae is treated as a dis—
tinct species rather a variety of E．sphaericus．E．atro-punctatus is reported from Guangxi for the first time．

Elaeocarpus sylvestris(Lour．)Poiret var．haya—
tae(Kanehira& Sasaki)Y．C．Liu，Lign．P1．Taiwan
376．1972．
This species was originally described as having a
3一loculed ovary．In Kanehira’s“Formosan Trees Re—
vised Edition”．the cross section of the ovary is illustra—
ted clearly as 3一loculed but the cross section of fruit is
5一loculed with 4 locules degenerating(Kanehira，1936，
fig．388：G & I)．Examination of type materials by C．
E．Chang revealed that the ovary and fruit are 4一or 5一
loculed(Chang，1977，P1．766：1，4)．In the infrageneric
system of Elaeocarpus(Tang，1992)，species with 5一
loculed ovaries and fruit belong to Section Ganitrus but
species wi th 2一or 3一loculed ovaries and 1一loculed fruit
belong to Section Elaeocarpus．Since its ovary is 4一or
5-1oculed，E．hayatae is certainly not a member of the
Section Elaeocarpus but rather a member of the Sec—
tlon Ganitrus．
Since its leaves look sim lar to E．decipiens and
E．sylvestris，E．hayatae sometimes has been treated as
a synonym of these；however，as noted above E haya—
tae is in a separate section．
Only two species of the section Ganitrus are rec—
ognized in China，of which E．angustifolius Blame is
found in southern Yunnan．Elaeocapus hayatae Kane—
hira& Sasaki differs from E_angustifolius Blume in a
number of characteristics including glabrous(vs．pu—
bescent)branchlets，petioles，and abaxialleaf surfaces，
smaler leaves(7—13 X 2．5—3．5 vs．13—17 X 4-6 cm)，fe—
wer lateral veins(6—8 vs．10-13)，veins and veinlets dis—
tinctly(vs．poorly)anastomosing，sepals glabrous(vs．
puberulent)adaxially，petal segments 13—15(vs．15—25)，
and 4一or 5一loeuled(vs．5一loculed)ovary and fruit．In
view of these differences，we prefer to treat it as a dis—
tinct species rather than a variety． In addition，up to
date records of geographical distribution indicated that
they are allopatric．This species is endemi c to Taiwan．
The discovery of both 4一loculed and 5一loculed o—
varies and fruit mi ght be important in the study of evo—
lution of this genus． E．hayatae is distributed in the
periphery of the section and the reduction in locules of
ovary and fruit mi ght be derived．
