ABSTRACT. Myrsine africana L. var. glandulosa J. M. Zhang is a new synonym of M. africana var. africana.
Zhang (1995) described Myrsine africana var. glandulosa
as a new taxon, and he indicated that it differs from the type
variety in having fruits with dense black glands 0.5--1 mm long,
"pericarpio dense nigris glandulosis 0.5--1 mm longis."
An examination of the paratypes at KUN (e.g., C. W. Wang 83690
and J. S. Xin 6 from Yunnan and C. P. Song 39512
from Sichuan) readily reveals that that the alleged "black
glands" on the fruits represent nothing but fungal infection.
This fungal infestation appears to be quite common on fruiting
material, and additional diseased collections (all of which are
at KUN) not examined by Zhang are: CHINA. Yunnan: Yongren,
H. T. Tsai 52848; Kunming, C. W. Wang 62650, 62785;
Lijiang, T. T. Yi 8139; Zhongdian, K. M. Feng 3123;
Heqing, R. C. Ching 24212; Xundian, F. T. Wang 5884;
Luquan, P. I. Mao 1817; Songming, P. Y. Chiu 54209,
60697; Mengzi, C. W. Wang 83468. Sichuan: Muli,
S. K. Wu 3326.
The fungus is believed to be a species of Heydenia Keiss
of the Deuteromycetae (Imperfect Fungi), and the hemispherical
black tops of sporocladia were misinterpreted by Zhang (1995)
as glands. In addition to Myrsine africana, the fungus
also infests M. semiserrata Wallich (Tai, 1979), and both
species of Myrsine are distributed in the greater part
of South China (Chen, 1979).
