摘要:

The exine structure has been studied in Campanulaceae s. lat. The results are combined with those in previous studies of shape, sculpturing and aperture conditions. Fifteen further species have been studied by SEM. Two main groups of pollen are found: (1) porate pollen with spinules and ridges/protrusions or a low relief reticulum, combined with an ektexine varying from simple to complex and a lamellated endexine; (2) 3–colpate/colporate pollen with a high relief reticulate/striate surface sculpturing, in general a homogeneous ektexine and an endexine lacking lamellae. The first group corresponds to Campanulaceae s. str., the second to Lobeliaceae s. str. Some genera likeCyananthus, CodonopsisandParishellahave unique characters which make them difficult to place in any of the two main group

摘要:

Sanblasia dressleriis described from material from the Serranía de San Blas, E Panamá. The inflorescence has the general appearance of anIschnosiphon, but the ovary is 3–ovulate, as inCalathea, and the bracteole is channeled and keeled, as in many species ofCalathea, and inPleiostac

摘要:

Four new species are described, viz.Ischnosiphon bahiensis(Brazil),I. ursinus(French Guiana and Rio Negro Basin),I. crassispicus(vicinity of Manaus), andI. fusiformis(NE Peru). New data on ecology, morphology, or distribution are presented forI. inflatusAnderss.,I. enigmaticusAnderss.,I. centricifoliusAnderss.,I. gracilis(Rudge) Koern.,I. helenaeAnderss.,I. macarenaeAnderss.,I. polyphyllus(P.&E.) Koern., andI. surumuensisLoes. The typification ofI. arouma(Aubl.) Koern. is briefly discussed.

摘要:

In Vitaceae three new species ofCyphostemma(Planch.) Alston are described:C. boranenseVollesen,C. burgeriVollesen,C. pannosumVollesen. The new combinationsCyphostemma betiforme(Chiov.) Vollesen,C. dembianense(Chiov.) Vollesen andC. oxyphyllum(A. Rich.) Vollesen are proposed.Cayratia ruspolii(Gilg) Suesseng. is transferred back to the genusCissus L.In Burseraceae the new combinationCommiphora kua(R. Br. ex Royle) Vollesen is proposed.

摘要:

An attempt is made to clarify some recent confusion concerning the understanding of the sectionCymboglossumSchltr. of the genusEria.Study of literature and material of the taxa involved leads to the suggestion that the section should be recognized withinEriawith so far only one species known to belong here, while at the same time the establishment of a new genusAscidieriatypified byEria longifoliaHook. fil. and the maintenance of theEriasect.SecundaeLeavitt typified byEria strictaLindl. is proposed.

摘要:

Phyllanthus bruneliiRoux, a new shrubby species from Thailand is described.P. bruneliihas apparently until now been confused withP. reticulatusPoir. Its pollen structure suggests affinities between the subgeneraKirganelia(A. Juss.) Webster andGomphidium(Baill.) Webster.
