摘要:

Stigmas in 24 species of 11 genera, classified in three groups,Caesalpinia, PeltophorumandDimorphandra,of the tribe Caesalpinieae have been examined by light and scanning electron microscopy. All are of the WN (wet, non‐papillate) form. The receptive stigmatic surface comprises a crater, generally at the apex of the style, which in fresh flowers is full of clear fluid. The crater rim may be fringed with non‐receptive hairs, and its shape and depth are variable between species. Extreme forms are found inCaesalpinia sappanwhere crater hairs are short and the crater funnel‐shaped and very deep, andC. vesicariaandDelonix regiawhere crater hairs are long and the crater appears very sh

摘要:

On the basis of the study of the original material used by Planchon, the typification previously made by other authors is discussed, and an interpretation of theU. minor‐galligroup is presented. We conclude that the nameU. gallimust continue in use in its traditional sense, and, therefore,U. cantabricusAlvarez Martínezel al.must become a mere synonym. The new combinationsU. breoganii(Castroviejo&Valdés‐Bermejo) Castroviejo&Valdés‐Bermejo,stat. nov.andU. minorsubsp.gallii(Planchon) Castroviejo&Valdés‐Bermejo,comb. nov.a

摘要:

A discussion of the little‐known and poorly localized Linnaean speciesVitis heptaphyllais presented. Its long, though sometimes questioned, association with Middle America arose from J. E. Smith's annotation of the probable type specimen (No. 281.10, LINN) as a possible member ofSciodaphyllumand his association of the name with the JamaicanAralia sciodaphyllumWilld. [sic](Schefflera sciodaphyllum(Sw.) Harms) in Rees' Cyclopaedia. However, the plant is the same as the East Asian tree described asAralia octophyllaLour, and known almost universally since the 1890s asSchefflera octophylla(Lour.) Harms. A formal treatment, incorporating the necessary new combination, is given. Notes on six other LinnaeanMantissa alteraspecies claimed, likeVitis heptaphylla,to be from “India orientalis” but without supporting references, are given in an App

摘要:

InP. affinis,pin pollen is shorter on average than thrum pollen. Pins have more coronal hooks on stigmatic papillae than thrums, but gaps between papillae are relatively smaller for thrums. Pin stigmas receive more pollen than thrum stigmas. Thrum stigmas receive more (dissortive) pin pollen, but pin stigmas are assortively pollinated. Pollen only germinates when trapped below papilla coronas. On thrum stigmas, most trapped pollen is pin. Pollen germination is better on thrum stigmas than pin stigmas, and thrum stigmas show a close relationship between numbers of legitimate pollen grains, numbers of germinating grains, and numbers of pollen tubes in the style. There is no inhibition of illegitimate pollen germination. Illegitimate pollen tubes are inhibited in the style. Incompatibility operates by a combination of dissortive pollination, dissortive pollen trapping, and stylar pollen tube inhibition. All heteromorphic features differing between pins and thrums are implicated in the inhibition of within‐morph fertilization in thrum

摘要:

The ontogeny, morphology, histochemistry and nuclear structure of glandular hairs inValeriana officinalisL. subsp.collina(Wallr.) Nyman were investigated. An interesting characteristic of these glandular hairs is their remarkable variability, not only in morphology, but in their chromatin activity, and the reactions of the secretions to histochemical tests.
