楼梯草属苞片形态和演化趋势

(Ⅰ)对荨麻科楼梯草属的苞片和小苞片的形态进行了全面研究。(Ⅱ)该属原始群疏伞楼梯草组的雄聚伞花序苞片在每花序为15-90枚,纸质,绿色,狭卵形、狭三角形或条形,长0.5-4mm,扁平,无任何突起,而与楼梯草族的冷水花属和赤车属的聚伞花序苞片极为相似,因此,上述各种形态可以视为楼梯草属苞片的原始特征,并据此观察到总苞苞片的以下演化趋势:(1)近等大,形状相似,在花序托边缘轮生形成一层→排列为二层,外层2苞片对生,较大,内层苞片较小,形状稍不同;(2)狭卵形,狭三角形或条形→宽卵形或宽三角形,或扁半圆形→由于长度强烈缩小,宽度增大而最终消失;(3)扁平→顶端兜形→船形→船形,顶端突起成细筒;(4)无任何突起0背面有1龙骨状突起,或有1-6条纵肋或狭翅1顶端具短到长的角状突起→背面顶端之下具角状突起;(5)分生→基部合生→由于长度强烈缩小,宽度强烈增大,总苞苞片合生成一横条形狭片;(6)在数目上,由每花序的7-45枚,一方面增加到50-180枚,另一方面则减少到5枚以下。同时,观察到小苞片形态以下演化趋势:(1)膜质,半透明,白色0具褐色线纹或呈褐色→呈黑色1薄膜质,透明,无色;(2)扁平→顶端兜形→船形;(3)无任何突起→顶端或在背面顶端之下具角状突起;(4)在数目上,由每花序的7-45枚一方面增加到100或数百枚,甚至达1千到数千枚,另一方面则减少到5枚以下,甚至到0枚。上述演化趋势有助于了解属下各级分类群的演化水平。

A Study on the Genus Acidosasa of Bambusoideae

The genus Acidosasa was published by the present authors in 1979. It only had one species at that time, Acidosasa chinensis C. D. Chu et C. S. Chao. Since then species number of the genus steadily increases. The authors have rather comprehensively studied this genus and its related genera for F1. Reip. Pop. Sin. The present paper deals mainly with morphological characteristics of the genus Acidosasa and the differences from its related genera i. e. Arundinaria, Sasa and Indosasa. The genus Acidosasa is closely related to the genus Arundinaria in the type and origin of inflorescences and the vegetative appearance. But it differs from Arundinaria in the structure of florets. In Acidosasa, each floret is provided with six stamens, while in Arundinaria each floret is of only three stamens. The genus Acidosasa is similar to the genera Indosasa and Sasa in the numbers of stamens, but it is distinguished from lndosasa by its semelauctant (determinate) inflorescence, not iterautant (indeterminate) one, from Sasa by its taller stature and branch complement with three branches. We have carefully examined all the type specimens of Acidosasa and its related genera. A conclusion reached is that there are six species in the genus Acidosasa, most of which are native to S. China, with only one species in Viet Nam. Five specific binomials are reduced and one species is transferred into this genus. Two keys to species, respectively based on the flowering and vegetative characters, are given as follow: Key to species of the genus A cidosasa (1)(based on the flowering state) 1. Lemmas glabrous. 2. Spikelets stout, 3-6mm broad, pedicels 1.5-4cm long; lemmas large, 1.5-2.2cm long, with 15-19 nerves, subcoriaceous, not glaucous, shiny. 3.

Spikelets rather slende, 2-4mm broad, pedicels 0.5-1cm long; lemmas small, about 1.3 cm long, with 7-13 nerves, more or less glaucous .......... 3. A. chienouensis 1. Lemmas pubescent. 4.

Culm-sheaths without auricles and oral setae, not farinose, without hairs at base. 5. Young culms densely bristly; culm-sheaths attenuate at apex and as wide as sheath-blades, with conspicuously transverse veinlets; leaf-blades large, usually 2.5-3.5 (-6.5) cm broad, conspicuously tessellate ..................................................... 1.

Notulae De Ranunculaceis Sinensibus(ⅩⅩⅡ)

(1) In the overwhelming majority of genera of the family Ranunculaceae, includ ing its primitive genera, Caltha, Calathodes, and Trollius and the primitive genus of trib. Anemoneae, Anemone, the sepals are spreading and the stamens are glabrous. So, the as cending or upright sepals and hairy stamens of the sections Meclatis, Tubulosa, Viorna, and Atragene of the genus Clematis are secondary, and are accordingly considered as advanced characters, and those sections and the genus Archiclematis, closely related to Sect. Viorna Subsect. Connatae, more or less advanced groups. (2) In the sections Cheiropsis, Fruticella, and Viticella, which have glabrous stamens,some species have spreading sepals, and the others have ascending or upright sepals. In Sect. Clematis, all the species have spreading sepals and glabrous stamens, except for Clematis pinnata, which has ascending sepals and usually hairy stamen filaments. In Sect. Lasiantha with 2 species restricted to western U. S. A., C. lasiantha has glabrous stamens, while C. paucifiora has stamens hairy on fliaments. In Sect. Naraveliopsis with spreading sepals,the majority of species have glabrous stamens, but one species, C.liboensis, endemic to Guizhou Province, China, has hairy stamens. These facts just mentioned indicate that the evolution of sepals and stamens took place in several lineages independently in Clematis. (3) In Clematis, glabrous stamens of C.apiifolia, C.grata, and C.montana with linear filaments and oblong anthers, are similar to those of Caltha, Calathodes, Trollius, and Anemone. Thus, the linear filaments and oblong anthers are considered primitive characters in Clematis. On the other hand, lanceolatelinear filaments of C. tangutica and C. aethusifolia or oblanceolate -linear filaments of C. courtoisii and C. loureiriana and linear anthers of C. meyeniana and C. uncinata, and narrow-linear anthers of C. courtoisii and C. lanuginosa are considered advanced ones. In ease of stamens with hairs, stamens of C. henryi with densely villous filaments and those of C. kweichowensis with both filaments and anthers densely pubescent show more advanced condition than those of C. pinnata, C. heracleifolia, and C. tangutica, with sparsely puberulous filaments and glabrous antbers(Fig. 1 ). (4)The pedunculate, 2-bracteate dichasial cyme with several flowers may represent the primitive type of inflorescences in Clematis. Manyflowered panicle-like cymes as in C.gouriana and C. tsaii, or few-l-flowered cymes as in C. henryi and C. repens, and cymes lacking peduncles and bracts as in C. montana and C. pogonandra are all considered advanced. Besides, the fact that flowers arise from axillary buds of old branches shows also an advanced condition. (5)Sect. Clematis subsect. Pinnatae, with leaflets, inflorescence ramification, and stamens similar to those of C. heracleifolia, is considered intermediate between Sect. Clematis and Sect. Tubulosa. (6) Subsect. Clematis and Subsect. Rectae, and Subsect. Connatae and Subsect. Crispae are so closely related to each other respectively that it is difficult to ascertain the systematic position of some intermediate species between the two subsections of each pair in the absence of seedlings. So, in the present paper, following the classification of Clematis proposed by Tamura in 1967, I put Subsect. Clematis and Subsect. Rectae in Sect. Clematis, and Subsect. Connatae and Subsect. Crispae in Sect. Viorna. (7)According to the evolutionary tendencies mentioned above, a realignment of the sections and the infrasectional taxa of the Chinese Clematis is made. (8) Six subsections, 6 serise, 2 species, and 4 varieties are described as new, and 5 new combinations, 4 new ranks, and 2 new names are given. (9)The specific rank of C. tenuipes W.T. Wang, reduced to varietal renk in 1980, is restord. C. taiwaniana Hayata, reduced to synonomy of C. grata Wall. in 1991, is considered distinct from the latter in hairy adaxial surface of sepal and narrower achene with tapering apex. C. kerriana Drumm. & Craib and C. laxipaniculata Pei are proved to be conspecific to C. subumbellata Kurz and reduced to syn-onymy.

Persson & Delprete sp. nov. occurs in Panama and northwestern Ecuador (Awá Reserve) and is characterized by its long drip tips and glabrous to minutely puberulent corollas. Duroia valesca C. Persson & Delprete sp. nov. is from the Atlantic forest of Brazil (states of Espírito Santo and Minas Gerais) and is distinguished by its heteromorphic calyx lobes that are large, 13–15×7–8 mm, elliptic and contorted in female flowers, whereas the calyx lobes of the male flowers are 3–5×1–2 mm and narrowly triangular.     

Prunus pananensis (Rosaceae), a New Species from Pan'an of Central Zhejiang,China

Prunus pananensis Z. L. Chen, W. J. Chen & X. F. Jin, a new species of Rosaceae from central Zhejiang, China is described and illustrated. Micromorphological characters of the indumentum on young shoots, leaves, petioles and peduncles, including scanning electron microscope [SEM] images, are provided. This new species is morphologically similar to P. schneiderianae Koehne in having its young shoots, petioles and pedicels all densely villose, but differs in having bracts persistent, styles glabrous, stipules 8–9 mm long, stamens 28–30 of per flower, and drupes glabrous. The new species is also similar to P. discoidea (Yü & C. L. Li) Yü & C. L. Li ex Z. Wei & Y. B. Chang in having 2 or 3 flowers in an umbellate inflorescence, and bracts persistent and marginally glandular, but it differs in having young shoots and petioles densely covered with yellowish-brown villose trichomes; leaves rounded or slightly cordate at base, the mid-ribs and lateral veins abaxially densely covered with yellowish-brown villose trichomes; and hypanthium ca. 3 mm long, shorter than sepals. The atpB-rbcL and trnL-F intergenic chloroplast spacers are selected for identification of the new and its similar species.
