芒苞草亚科——石蒜科的一新亚科

 Acanthochlamydoideae, a new subfamily of Amaryllidaceae, is proposed in the pre- sent paper, based upon the monotypic genus Acanthochlamys which was detected by the writer in 1979 and named Didymocolpus as a new genus but was preceded by P. C. Kao in 1980 under the former name.  The genus is indeed of great morphological in- terest. It has semicylindric leaves with a deep furrow on the ventral and dorsal sides respectively.  The lower part of the leaf is connate with, or adnate to, the lower mid- rib of a rather large and membranous vagina . Such a feature, as far as we know, is very rare in the monocotyledons.      The flower resembles that of Amaryllidaceae in having inferior ovary, six stamens and corolla-like perianth with a rather long tube.  But it is quite different in other characters, such as head-like cyme, leaf-like bracts and bisulcate leaves, which all are foreign to any taxon known in the Amaryllidaceae.  On the other hand, it bears some resemblance particularly in habit and inflorescence  to  Campynemanthe  of  the Hy- poxidaceae, and also to Borya and Bartlingia of the Liliaceae (in the tribe John- sonieae), but differs in its long perianth-tube and curious leaf structure.  It is highly probable that the resemblance between them is only superficial and not indicative of direct or close relationship.      This is no doubt a very curious plant of which we still know incompletely, and for which an appropriate place in the monocotyledons has not yet been found.  Con- sidering its floral characters, however, it seems safe for the present to place it as a separate subfamily in the Amaryllidaceae and is juxtaposed with the Ixiolirioideae and Amaryllidoideae, the only two subfamilies of Amaryllidaceae according to H. Mel- chior (1964), and, of course, to either of them it is not directly related. Its true affinity remains problematic.      The only species, Acanthochlamys bracteata, is found in Mar-er-kan (102°12'N, 31°47'E), Qian-ning (101°30'N, 30°33'E), Xiang-cheng  (99°39'N, 28°54'E)  and Dau cheng (100°10'N, 29°03'E) in western Sichuan of southwest China, in open bushland or grassland at an altitude between 2700—3500 meters.  Its geographical distribution is mapped and its morphological details are illustrated to facilitate its identification.       

茶树品种分类的探讨

  It is generally accepted that tea plant (Thea sinensis L.) is originated in China, where has numerous varieties,  According to the literature, the selected work of tea plants may be traced as early as to the 3rd-5th century A.D.  The number of varie- ties discovered in recent years reached more than 300.  Besides, a large number of wild species were discovered. In all tea varieties, the crown canopy, leaf size and the date of sprouting were different.  It was proposed that according to the crown canopy, leaf size and the date of sprouting.   The  principle of the classification  of Chinese tea varieties may be 3 orders.  The first order named “group”, it contains macrophanerophyte group, microphanerophyte group, and frutex group.  The second order named “type”, it contains extreme large leaf size, large leaf size, medium leaf size and small leaf size.  The third order named “species”, it contains the early- sprouting species, medium-sprouting species and late-sprouting species.
