A New Variety and New Varietal Combinations in Chinese Verbenaceae

During preparation of the treatment of Verben- aceae for the Flora of China, it became evident that the nomenclature of several infraspecific taxa in various genera needed adjustment. I propose the following novelties in order to make these names available for this and other Chinese floristic works now in progress. A new variety and three new va- rietal combinations in Callicarpa and one new com- bination each in Vitex and Clerodendrum are pro- posed.

Callicarpa

Callicarpa prolifera C. Y. Wu var. rubroglan- dulosa S. L. Chen, var. nov. TYPE: China. Northern Guangxi: Da-Miao Shan, 890 m, X. Q. Chen 14461 (holotype, IBSC).

A varietate prolifera foliorum laminis anguste lanceo- latis, (6-)12-16(-19) x (1-)2-4 cm, basi decursivis sub- sessilibus, utrinque subglabris, ad paginam inferiorem rub- roglandulosis; calycibus, corollis et staminibus dense rubroglandulosis differt.

Paratype. CHINA. Northern Guangxi: Da-Miao Shan, H. Lu 2783 (IBSC).

Callicarpa prolifera var. rubroglandulosa is readily distinguished from the type variety by its narrower leaves and by the dense reddish brown glands on the lower leaf surfaces, calyces, corollas, and stamens.

Callicarpa integerrima Champion var. chinen- sis (Pei) S. L. Chen, comb. nov. Basionym: C. formosana Rolfe var. chinensis Pei, Mem. Sci. Soc. China 1(3): 30. 1932; C. pedunculata R. Br. var. chinensis (Pei) Metcalf, Lingn. Sci. J. 11: 405. 1932. TYPE: China. Guangdong: Changkiang to Chengkou, Dec. 1927, Chun 5828 (syntypes, UC n.v., A).

In Callicarpa integerrima var. chinensis the leaves, pedicels, calyces, corollas, and ovaries are glabrous, or the leaves are pubescent only when young. In contrast, in var. integerrima the leaf blades are yellow-brown, stellate tomentose adaxially and gray-yellow, densely tomentose abaxially, and the pedicels, calyces, and ovaries are stellate to- mentose.

Callicarpa giraldii Hesse ex Rehder var. chin- yunensis (Pei & W. Z. Fang) S. L. Chen, comb. nov. Basionym: C. chinyunensis Pei & W. Z. Fang, Fl. Reipubl. Popul. Sin. 65(1): 209. 1982. TYPE: China. Sichuan: Beibei, Jin- yun Shan, S. J. Wang 1109 (holotype, NAS).

This variety differs from the other two of Cal- licarpa giraldii by its purple-brown branchlets with distinct lenticels, its denser cymes, and its leaves with obtuse or rounded base, gray-brown, densely stellate lower surface, and hispidulous-scabrous up- per surface.

Callicarpa longipes Dunn var. mixiensis (Z. X. Yu) S. L. Chen, comb. nov. Basionym: C. mix- iensis Z. X. Yu, J. Jiangxi Agr. Univ. 1: 1. 1982. TYPE: China. Jiangxi: Ruijin Xian, Mixi, Z. X. Yu 1315 (holotype, Herb. Forest Dep. Jiangxi Agr. Univ.).

Callicarpa longipes var. mixiensis is easily dis- tinguished from the type variety in having whitish fruits and leaves that are yellow-glandular on both surfaces. Variety longipes has purple fruits and pilose leaves that are yellow-glandular abaxially.

Vitex

Vitex trifolia L. var. taihangensis (L. B. Guo & S. Q. Zhou) S. L. Chen, comb. nov. Basionym: V. taihangensis L. B. Guo & S. Q. Zhou, Bull. Bot. Res. 9(4): 61. 1989. TYPE: China. Shanxi: Tai Hang Shan, 1,400 m, 15 Aug. 1986, Guo Lan-bin 688 (holotype, NMFC).

Characters that separate var. taihangensis from the type variety are the presence of simple instead of trifoliolate leaves, and glabrous, eglandular, in- stead of glandular, ovaries.

Clerodendrum

Clerodendrum chinense (Osbeck) Mabberley var. simplex (Moldenke) S. L. Chen, comb. nov. Basionym: C. philippinum Schauer var. sim- plex Moldenke, Phytologia 20: 338. 1970. TYPE: Thailand. Ban Musseo: between Tak

and Mae Sot, 400 m, 21 July 1959, F. Floto 7634 (holotype, Moldenke Personal Herb. (Plainfield, New Jersey n.v.).

Variety simplex is readily distinguished from the type variety in having single instead of double flow- ers. It grows in forests and along streams in Guangxi, Guizhou, and Yunnan, whereas var. chinense is

cultivated in Yunnan, Guangxi, Guandong, Fujian, and Taiwan, as well as in other parts of tropical and subtropical Asia.
