The article introduces our study on the history of Ehretia dicksoni Hance. Its typical specimen is collected in Hubei. Tra-dition says that Ehretia dicksoni is distributed in the southeas-tern and southwestern parts of China while E. macrophylla Wall.in east Himalayas (Nepal and Bhutan) and Vietnam. But our studies have proved that they belong to the same species. our reason is as follows:1. If we consider the racemose or corymbose arrangement of flowers on the inflorescence's branchlets as evidence of clas-sification, it is difficult for us to distinguish E. dicksoni fromE. macrophylla,according to our observation on their actual specimens. We have found that both of the different arrange-ments of flowers on the inflorescence's branchlets exist in numbers of specimens gathered in our country. Most of them present a corymbose arrangement. In addition, I. M. Johnston has distinguished E. dicksoni in our country from E. macro-phylla in Nepal by saying that the fruit of E. dicksoni has a diameter of 1-2cm. while according to the record in "F1. Brit.Ind".and "F1. Indo-chine", the fruit of E. macrophylla is 1.7 or 1.5cm. in diameter. This figure is within the extent repre-sented by Johnston. And so, it is not easy to differentiate. the fruit of the two. 2. As for the structure of the flower, the record of E. macrophylla in "F1. Brit. Ind.","F1. Indo -chine" and "DC.Prodr." fundamentally in comformity with the specimens in our country. 3. The geographical distribution of E. dicksoni links up with that of E. macrophylla. In Chayu (sontheast Xizang) we have found specimens of E. macrophylla, with abundant villu-lous on the lower surface and hispid on the upper surface of its leaves. In Nyalam (Xizang) we have also found glabrous specimens on the lower surface of its leaves. There is no doubt that they are E. macrophylla's sp. var., this sp. var. is also dis-tributed in Yunnan, Guizhou, Sichuan, Guangxi and Hubei.Therefore, our discovery of the specimens in Xizang gives evi-dence of the linkup of E. dicksoni and E. macrophylla in distribution from Yunnan and Sichuan in southwest China to east Himalayas. On this basis, we think that they are the same species with different names. They should merge into a single whole. The name of this sp. var. needs to be changed correspon-dingly:Ehretia macrophylla Wall. var. glabrescens (Nakai) Y. L.Liu, comb. nov.——E. dicksoni Hance var. glabrescens Nakai inJourn. Arn. Arb. 5:34. 1924.

The plant, nemed "Malien" in Chinense, belongs to Family Iridaceae, Genus Iris. It is distribute broadly in Northern China,Korea and the USSR. It's Latin name is very confused. The plant "Malien" which blooms violet flower is called Iris loctea Pall. var. chinensis Koidz. and the lactary flower is regarded as I. lectea Pall.;but rare. Another Latin name of "Malien" I. ensata Thunb. is a mis-taken identification. Its true plant should be "Yuchanhua" in Chinense, and. I. kaempferi Sieb. ex Lemair. is regard as a syno-nym, because it is a later name and therefore it is uneffective. There are two varieties which were nomenclatured under I. ensata Thunb., the first, var. spontaenea (Makino) Nakai, and the second, var. nortensis Makino et Nemoto, The former is regard as the synonym of the specific name, bat the latter,named "Huachangpu" in Chinense which is broadly cultivated in Japan and China is all right. I. illiensis Pol. may be regarded as I. lactea Pall. var. chinen-sis Koidz. In Tibet there is another "Malien" which blooms yellow flower. It is also a variety of "Malien", called I. lactea Pall.var. ehrysantha Y. T. Zhao, var. nov.

This species was based originally by V. L. Komarov as Me-dicago gordejevi Kom., and then A. A. Grossheim transferred to Trigonella. But the type is characterized by petals persistent after flowering, the claws of wings and keel adnate to the sta-minal sheath, filaments dilated at the apex, calyx-teeth longer than the tube, base of stipules encircling the stem, pod short and usually enclosed by the persistent corolla. For these reasons the plant must treated under the genus Trifolium, becomes:Trifolium gordejevi (Kom.) Z. Wei, comb. nov. known only from the eastern border of Heilongjiang and Jilin Provinces with slight extension into the ussuri regions.A new record to N.——E. China.
