The present paper deals with studies of the pollen mor-phology of the tribe Trigonotideae (Boragidaceac- Boraginoi-deae), containing five genera, i. e.

The pollen grainsof 26 species belonging to these genera respectively were exa-mined with the light microscope and scanning electron mi-croscope.

Trigonotis, Brachybotrys,Sinojohnstonia, Omphalotrigonotis and Mertensia. The pollen grainsof 26 species belonging to these genera respectively were exa-mined with the light microscope and scanning electron mi-croscope. The pollen morphology of the genera in question isdistinctly different between each other and may furnish valua-ble characters for distinguishing them and for supporting theestablishment of the new genus, Omphalotrigonotis, An analyti-cal key to the pollen grains of the five genere is as follows: 1. Pollen grains dumbbellform in equatorial view, moreor less constricted in equatorial region, tricolporate and tri-pseudocolpate. 2. Pollen grains the smallest in the tribe Trigonotideae. exine almost psilate…………………………Trigonotis Stey.2. Pollen grains larger, exine with ornamentations. 3. Exine foveolate…………………………Sinojohnstonia Hu 3. Exine fillely granulate or spinulate. 4. Exine finely granulate…………………………Mertensia Roth. 4. Exine spinulate………………………… Blachybotrys Maxim. ex Oliv.1. Pollen grains rhombic in equatorial view and not constricu-ted in equatorial region, tricolporate, not pseudocolpate.exine finely reticulate………………………… Omphalotrigonotis W. T. Wang

There are five genera of Nymphaeaceae in China: Nelumbo,Brasenia, Euryole, Nymphaea and Nuphar. Pollen morphology of2 varieties, 11 species representing 5 genera was examined underlight microscope and scanning electron microscope. The struc-ture of exine of Nymphaea alba and Nelumbo nucifera was alsoexamined under transmision electron microscope. According to the type of aperture, it may be divided intothree types: (1) Anasulcate type, Brasenia, Euryale and Nuphar.Pollen grains long ellipsoidal and ellipsoidal in polar view,and boat-shaped in equatorial view. Ornamentation of exinegranulate in Byesenia, spinulate in Euryale and long spinate inNuphar. (2) Zonasulculate type: Nymphaea. It may be subdividedinto anazonasculate and zonizonasculate type. Pollen grainscircular in polar view, and circular or subcircular in equato-rial view. Ornamentation of exine tuberculate, granulate orspinulate. (3) Tricolpate type: Nelumbo. Pollen grains subc-ircular in polar view, and subcircular or ellipsoidal in equa-torial view. Ornamentation of exine rough granulate underlight microscope, but rugulate under scanning electron micro-scope. The structure of exine Nymphea alba and Nelumbo nuciferawere examined under transmision electron microscope. The for-mer has a granular structure with more or less homogeneousgranules, but the latter a collumellar structure. According tothe idea about the evolution of pollen grains in primitive Angi-osperms proposed by Walker, the type of granular structure isa primitive type, and that of collumellar structure a advencedone. A number of taxonomists have considered that Nymphaeaceaeis a primitive and heterogeneous family. On the basis of thepollen morphology of this family, it may be supported for thisview - point. The evolutionary relationships among the pollen grains inthis family was also discussed.

The pollen morphology of 52 species and 2 varieties belong-ing to 21 genera of Rutaceae from China was examined by meansof light microscope of which 6 species examined by means ofscanning electron microscope. The pollen of Rutaceae belongs tostenopalynous. According to numbere of the opertures and orn-amentation of exine the pollen of the family can be divided intotwo types: tricolporate and 4--6 colporate. A pollen morphologykey has been shown in this paper based on the pollen charac-ters. In addition, new conbination in Zanthoxylum and Fagara andclose affinity between Zanthoxylum and Evodia were discussed inthe present study The pollen grains of the family prolate-subspheroidal or ob-late,3-6 lobed-circular or subcircular in polar view. Polar axis×equatorial axis=(18.2-72.8)×(12.3-54.6). The smallest pollenare found in Zanthoxylum dimorphophyllum Hemsl., (20.0-25.0) 22.5×15.0(12.5-17.5). The lagest pollen grains are in Micromelumpubescens Bl.,(46.8-72.6)59.8×46.8 (39.0-54.6). Tricolporatepollen type is common in the family, but 4-6 colporate typesare rarely found. The colpi are usually long and narrow withmembrane The margin of some colpi are usually thickened.Somepollen are syncolpate in polar view, longicolpate with lalongateora. The colpus and os intersect each other and They form across-mark in the equatorial view. Exine about 1.5--4.0 thick,sexine thicker than nexine. The columella layers are clearly vi-sible. The ornamentations of exines are reticulate and striate. Based on numbers of the opertures and ornamentation of exine21 genera can be divided into two types and four subtypes: 1. Tricolporate (1) The tricolporate with reticulate ornametation; (2) Tri-col porate with striate ornamentation. 2. 4-6 colporate (1) 4-6 colporate with reticulate ornamentation; (2) 4-6 colporate with striation ornamentation.

本文用光学显微镜对我国21属52种2变种芸香科(Rutaceae)植物的花粉形态进行了详细地观察研究,其中对6属6种进行了扫描电镜观察。本科花粉具沟孔,是花粉单类型的科之一。根据萌发孔的数目和外壁纹饰特点,本文将芸香科的花粉分为具3孔沟和4—6孔沟两个花粉类型,并根据各属花粉形态特征,作出了花粉形态分属检索表。此外,本文还对花椒(Zanthoxylum L.)和Fagara两属的合并问题及花椒与吴茱萸(EvodiaScop.)两属之间的亲缘关系等问题进行了讨论。
