The recent opportunity of examining the faecal material of the water-scorpion Leccotrephes japonensis revealed a flagellate which had not previously been described from this host. After fuller investigation I found that it is a species new to science and should be referred to the genus Retortamona; I have named it Retortamonas leccotrephae sp. nov.The specimens of Leccotrephes japonensis used for studies on the parasitic flagellate R. leccotrephae, were collected from ponds on the outskirts of Shanghai, China. Apart from studying the living flagellates, at the same time stained specimens were prepared for the detailed study of various structures. These specimens were fixed either in Hollande's or in Schaudinn's fluid; stained in Heidenhain's haematoxylin, and destained in 2% aqueous phospho-tungstic acid. Moskowitz' (1950) modification of the Protargol impregnation method was also used for staining.In the living state, the flagellare has a slender, slipper-shaped trunk with an anterior dorsal flexure. The mean body size, exclusive of the posterior spike, is 12.8μ×4.8μ. The length of the slender posterior spike varies from 4.6μ to 15.8μ. There are two flagella of unequal length. The longer one extends forwards and lashes rapidly, causing the animal to rotate and to pursue a special course. The shorter flagellum is directed backwards and usually lies in the cytostome; it moves in an undulating manner.In fixed and stained preparations, the flagellates, not including the posterior spike, show a size-range of 6.2×2.2μto 15.6×5.4μ, with a mean of 11.9×3.4μ. The spike varied from 4.6μ to 13.6μ long, with an average length of 11.2μ. In general, a normal specimen of R. leccotrephae has a slender body; the anterior portion is narrower than the postcerior, and is markedly bent as shown in the living indivi.duals. The posterior portion of the body usually has a dorsal convexity, and the widest region is located near the two-thirds of the body-length from the anterior end.Near that edge of the nuclear membrane lying next to the cytostome, there are two minute, but separate, basal granules which give rise to the two flagella. The anterior flagellum is about as long as the body proper: much longer and more slender than the posterior flagellum, which usually lies within the cytostome, and commonly shows a series of two or three undulations; it often stains more deeply than the anterior flagellum.In hematoxylin preparations the nucleus is well stained, and clearly shows a layer of chromatin granules lying against the nuclear membrane, and a large central endosome, composed of a mass of granules.The cytostome is a large structure in this animal. It usually occupies about twothirds of the total length of the body proper. Along the margin of the cytostome there are two deeply staining fibres, the one on the right margin is longer than that on the left.Both the precystic forms and cysts of R. leccotrephae have been observed. The body of precystic individuals which are preparing to encyst, becomes smailer and rounds up; meanwhile, the chromatin of the nucleus condenses and forms a deeply staining endosome. The anterior flagellum is still disposed freely, and no cyst wall has as yet been formed. The border-line of the cytostome is distinct, but the two basal granules are visible only in favourable preparations. The mature cysts are nearly peanut-shaped, and are about twice as long as wide. In the stained specimens they are about 4.6μ long and 2.4μ wide. The cyst wail is of uniform thickness, and the nucleus is visible at one end. The other conspicuous structures within the cyst are the two flagella and the cytostomial fibres, which are arranged as they are in the trophozoite, except that the anterior flagellum is here directed posteriorly.DISCUSSION & SUMMARYIn its general body-form, R. leccotrephae closely resembles Mackinnon's R. agilis ('11) from crane-fly larvae, and also Corradett's R. gryllotalpae ('37) from the mole cricket, but it is especially like Geiman's R. caudacus ('32) from the aquatic larvae ef certain beetles.

红娘华蛐的身体结构,一般与Mackinnon所述的R.(Embadomonas) agilis和Corradetti所述的R.grillotalpae相似,特别近似Geiman所述的R.caudacus(图15,16)。但红娘华蛐有大约等於体长2/3的大胞口,和长於或等於体长的针状尾巴,而且无论在生活时或固定染色後,头部均向背後扭曲(此较图1和15)。这些特性,显然与过去文獻中所记载的种类不同,故(氵夬)定为蛐属——新种。

Pai-chih is one of the important Chinese drugs. As with most of the umbelliferous drugs, its botanical origin is in many respects confusing. By a preliminary study on the plant specimens collected from 10 principal localities where Pai-chih is either under cul- tivation or growing wild, the authors have idenhfied 7 species, representing 2 genera, namely Angelica and Heracleum of the parsley family.

Pai-chih is one of the important Chinese drugs. As with most of the umbelliferous drugs, its botanical origin is in many respects confusing. By a preliminary study on the plant specimens collected from 10 principal localities where Pai-chih is either under cul- tivation or growing wild, the authors have idenhfied 7 species, representing 2 genera, namely Angelica and Heracleum of the parsley family. A brief account about the de- tails is given as follows: 1.Chuan pai-chih (Szechuan pai-chih) is derived from two species of plants, namely Angelica dahurica Benth. et Hook., and A. anomeld Lall. Tu pai-chih is Heracleum hemsleyanum Diels, is used in Szechuan only. 2.Hang pai-chih (Hangchow pai-chih) is essentially from Angelica formosana Boiss. This plant originally described from a Taiwan specimen, has been treated as identical with Angelicd dahurica by some authors, and here is retained as a good species on account of the following facts: its stem is comparatively slender, umbels with less than twenty rays, bractlets shorter than its pedicels, flowers yellowish green during anthesis; mericarps pilose at maturity, while in A. dahurica, the stem is rather stout and purpurlish, umbels with 22-40 rays with bractlets longer than or at least equal to its pedicels, and meri- carps glabrous at maturity. 3.Various samples that came from Honan known as Yu-pai-chih, from Hopei known as Chi-pai-chih, from Hunan as Hsiang-pai-chih, from Hupei as Eh-pai-chih, and from Anhuei as Po-pai-chih, are all identified as the same species, A. dahurica. 4.The name Heracleum lanatum Michx., a North American plant, has appeared both in the current Asiatic medicinal literatures and on the herbarium sheets for the ternate leaved Chinese Heracleum. By a careful comparison between the American species and our species, the authors have found that the former is by no means the same as ours. The presence of this American plant in this country seems highly improbable. The Hopei Heracleum Pai-chih which resembles somewhat Heracleum lanatum in the foliage appearance, is here identified as Heracleum moellendorffii Hance.

本文共收载全国10个白茫的主产地原植物,经研究结果,共有7种植物分属于繖形科当归属(Augelica)和牛防风属(Heracleum).川白芷原植物主要是兴安白芷Angelicadahurica Benth.et Hook.及库页白芷A.anomala Lall.其次,四川土白芷为川鄂牛防风Heracleum hemsleyanum Diels.杭白芷原植物主要为Angelica formosana Boiss.禹、祁、湘、鄂、亳白芷则均为A.dahurica.云南白芷据现时所得材料,只有云南牛防风Heracleum scabridumFr..本文并对兴安白芷和杭白芷二种的分合进行了讨论,确定将二者分开,各为独立种;并将A.dahurica var.pai-chi Kimura et al.列为A.dahurica的异名.又文献中河北白芷有定为Heracleum lanatum Michx.,经鉴定结果应是H.moellendorffii Hance.
