    Although the family Liliaceae is only represented by 54 genera with about 530 indigenous species in China, it is chara-cterized mainly by, first, most species and about four fifths of genera distributing in temperate flora; second, core group (Li-liaceae s. str. of Dahlgren Clifford) such as Lilium, Cardiccri-num, Notholirion, Nomocharis, Fritillaria, Lloydia etc., highly dif-ferentiating; and third, the circumscription of some group, such as Gagea and Llcydia being merged in this country, though rather distinct from one another elsewhere. Needless to say, Chinese Liliaceae may be proved to be a fruitful group in stu-dying the origin and differentiation of East-Asian Flora. After a brief comparison of systematic positions of Chi-nese Liliaceous genera in 4 different systems (Krause 1930;Hutchinson 1934, 1973; Takhtajan 1969, 1980; Dahlgren & Clifford 1982), the authors have made some suggestions on future studies as follows. 1. The probable heterogeneous groups, such as Aspidistreae etc., would need more intensive monographic studies. 2. Groups, highly differentiating in China, such as Lilium, Cardiocrinum, Notholirion, Nomocharis etc, may be selected for biosystematic studies. 3. Genera, such as Milula etc.; still uncertain of systema-tic position would need further studies. 4. Groups, such as Ypsilandra of East Asia and Helonias of N. America, which are primitive in chatacters and disjunct in distribution, may be selected for phytogeographical studies. 5. Groups, such as Paris, Trillium, Cloriosa, Tupistra, Reine-ckea etc., which are or may be chinese medicinal herbs, may be selected for pharmacological and phytochemical studies. 6. Undoubtedly Liliaceae s. 1. is a heterogeneous group.So relatively primitive groups, such as Helonieae, Tofieldieae etc. and groups displaying probably close relationships with other families, e. g. Petrosavia (with Triuridaceae), Hosta (with Agavaceae), Paris and Trillium (with Stemonaceae) etc., may be worth intensively studying for understanding evolutionary tren-ds in Monocotyledons.

    Restored as a distinct genus in 1961 by Tindale, the fern genus Arachniodes D1. has so far not yet been monographically studied, its exacte rande of distribution and total number of species remaining unknown in the world. From the Asian main-land including Taiwan province of China and Japan the confu-ssed genus has recently been revised by prof. R. C. Ching and the present author and, as a result, there are 116 species, thus constituting a medium--sized genus of the family Dryopteridaceae with Polystichun and Dryopteris being the largest genera each, represented by more than 200 species in the world. Taxonomically, the genus is rather difficult to deal with because great majority of the species are more or less similar in the degree of division of lamina, shape of ultimate pinnules, type of serrature, and form and color of scales on stipe and rachis. The classification scheme proposed in the present paper is based upon about 130 species of the genus from Asia and may serve as well the classification of a few species from extra-asi-atic regions.

    This paper deals with the pollen grains of 16 genera, 46 species, 2 variety in Chinese Convolvulaceae. Acomparative stu-dy on the pollen grains was carried out by means of scanning electron microscope and light microscope. The pollen grains of the family Convolvulaceae are eurypa-lynous. Tricolpate is the basic type. According to the shape, position and number of the aper-ture, the pollen grains are divided into the four types-tricol-pate, 4-11 colpate, pancolpate and panporate. On the basis of palynological data were discussed taxonomical position of the genus Cuscuta among the family Convolvulacaee and evolutionaltrend of the aperture of this family.
