For vegetative anatomy, see Metcalfefor some developmental morphology of ovules and seeds, fsmilia. The American Society of Plant Taxonomists.

For pollination – possibly sapromyophily – see Gottsberger a. Although hardly co-evolution, Luo et al. Indeed, there are a number of fossils perhaps to be assigned to the Nymphaeales-Austrobaileyales area from the Early Cretaceous see above for more discussion.


Such a family has been recognized by most taxonomists, at least for the past several decades. Lianeclimbing by twining; alkaloids 0, flavonols? The Cronquist systemoftreated the plants in the family in its wider sense as two separate families, which together constituted.

Columellar infratectal structure of pollen grains may be best optimised here; the plesiomorphic condition is granular, also found in the pollen of several Magnoliales, Monimiaceae, etc. II of placing the two parts of this quite well characterised clade in separate families, but combination seems in order A. The stigmas are postgenitally united by secretion Losada et al.

For the fossil record of Schisandraceae, which dates back only to the Late Cretaceous, see Friis et al. It places the family in order Austrobaileyaleswhich in turn is accepted as being among the most basic lineages in the clade angiosperms.


Botanical Journal of the Linnean Society. Some general information is taken from Bailey and NastKengand Saunders, Sy et al.

In Schisandraat least, the parts of the perianth that are exposed in bud are sepal-like on their exteriors Warner et al. Then there are the not-so-trivial issues of how character states are delimited and ancestral states are reconstructed see above. Similarly, Luo et al.

Dates are indeed interesting here. Some plants of Trimenia papuana have inaperturate pollen, while some have polyporate pollen Schisancraceae ; the endexine is lamellate.

For the circumscription of the order, see Soltis et al. Includes AustrobaileyaceaeSchisandraceaeTrimeniaceae.

It regarded both families as being among the most basic lineages in the clade angiosperms. Uses authors parameter Articles with ‘species’ microformats CS1 maint: Ages for this node of Kadsura may be paraphyletic, based on the analysis of both trn L-F and ITS sequences, although paraphyly is not found in morphological analyses Hao et al.

A genome duplication event has been placed at this level and dated to ca All groups below are crown groups, nearly all are extant. For some Early Cretaceous seeds that may be in this part of the tree, see Friis et al.

Williams and Friedman and Familiw et al. Friedman and Schisanvraceae The pollen is modified monosulcate via tritomosulcate. Details of pollination, with small diptera the commonest pollinators, have recently been clarified see especially Luo et al.


Retrieved from ” https: Molecular and morphological studies also suggest rather different relationships within Illicium Hao et al. The crown-group age of this clade is ca A fossil-based estimate for the age of this clade is ca m.

Cuticular striations are known to occur only at and above this node Upchurch See Bailey and Swamy and Endress for general information, Carlquist for wood anatomy, Behnke for phloem anatomy, pores are very narrow, Endress a, for floral morphology, Zavada for pollen c. Mexico, Greater Antilles map: There is the option in A. There is some discussion as to whether the highly inclined end walls of the sieve tube have sieve plates, or not Evert However, Friis et al.

Ages in Luo et al. Only female midges visited the flowers, and each species of Kadsurafor example, was visited by a different species of midge. For the ecophysiology of Austrobaileya scandensa liane schisandraceaf can tolerate shade, see Feild et al. The first pair of ages in particular are likely to be severe underestimates if the identity of the trimeniaceous fossil seed see below is correct.
