Abstract.Comparative studies on floral morphology, anatomy, and histology were performed to identify shared features of the genera of Apodanthaceae (Rafflesiales): Apodanthes, Pilostyles, and Berlinianche. Berlinianche was studied for the first time in detail and its affinity to Apodanthaceae was confirmed. It has a previously undescribed hair cushion on the inner perianth organs and inaperturate pollen. Shared features of members of Apodanthaceae are: unisexual flowers; three (or four… 

Comparative ontogeny of the cyathium in Euphorbia (Euphorbiaceae) and its allies: exploring the organ-flower-inflorescence boundary.

Indistinct boundaries between inflorescence, flower, and floral organs demonstrate that defining the Cyathium neither as an inflorescence nor as a flower is entirely satisfactory and indicate a "hybrid" flower/inflorescence nature of the cyathium.

The systematics of the worldwide endoparasite family Apodanthaceae (Cucurbitales), with a key, a map, and color photos of most species

Using morphological, nuclear, and mitochondrial data, the taxonomy of Apodanthaceae is revised and the 36 names published in the family are allocated to ten biological species in two genera, Apodanthes and Pilostyles.

First reports and generic descriptions of the achlorophyllous holoparasites Apodanthaceae (Cucurbitales) of Colombia

The Apodanthaceae (Cucurbitales) are one of the 12 parasitic clades of flowering plants and the only holoparasitic family with a vegetative phase entirely endophytic, growing primarily on Fabaceae

Stamen and pollen development in Menispermaceae with contrasting androecium structure

The development and morphology of stamens differed among the three genera, and the stamen primordia exhibited different patterns, in family Menispermaceae, which may have multiple evolutionary origins because this family does not form a single clade.

Flower Structure and Trends of Evolution in Eudicots and Their Major Subclades1

It is shown that features that are potential key innovations, because they characterize strongly diversified clades, are also sporadically present in species-poor clades more to the base of the phylogenetic tree, indicating that what appear as key innovations in certain groups may be present in latent form long before their manifestation as a key innovation.

Holoparasitic Rafflesiaceae possess the most reduced endophytes and yet give rise to the world's largest flowers.

It is concluded that the endophyte probably develops directly from a proembryo, and not from an embryo proper, and the flowering shoot arises directly from the undifferentiated endophytes, which is exceptional within angiosperms and warrants additional investigation.

Structure of staminate flowers, microsporogenesis, and microgametogenesis in Helosis cayennensis var. cayennensis (Balanophoraceae)

Despite the extreme reduction of flowers, the anatomic characteristics and gametophyte development of staminate flowers of H. cayennensis are perfectly normal and functional, thus highly similar to other genera of the holoparasitic subfamily Helosidoideae.

Meristem Genes in the Highly Reduced Endoparasitic Pilostyles boyacensis (Apodanthaceae)

The endoparasitic lifestyle of Apodanthaceae appears to correlate with a substantial reduction in the transcriptomic machinery linked to SAMs, whereas the genes involved in flower fate have remained intact.

Floral scent and pollinators of the holoparasite Pilostyles thurberi (Apodanthaceae)

GC/MS analysis of whole floral extracts and dynamic headspace samples revealed the fragrance to be an unusually simple bouquet of raspberry ketone and several eugenols, the first report of the constituents of floral fragrance in Apodanthaceae.

F LORAL SCENT AND POLLINATORS OF THE HOLOPARASITE P ILOSTYLES THURBERI ( A PODANTHACEAE )

Floral scent is likely important to the pollination of parasitic plants, despite that it has not been wellstudied. We studied the pollination ecology of the North American stem holoparasite

Because of a) many unusual and, in part, unique features and b) the lack of detailed comparative data for neotropical Rubiaceae, the genus' subfamilial and tribal position remains obscure.

Comparative structure of ovules and seeds inRafflesiaceae

Seed structure strongly confirms the existing subfamilial classification and supports additional arguments for the generic status of Apodanthes, and does not support a separate status of the genus Berlinianche.

The results strongly support three pairs of families in sister group relationships, as suggested by studies based on other characters: Cabombaceae-Nymphaeaceae, Saururaceae-Piperaceae, and Lactoridaceae-Aristolochi Families, and Hydnoraceae-Rafflesiaceae to some extent.

POLLINATION OF RAFFLESIA (RAFFLESIACEAE)

Experimental data indicate that both visual and olfactory cues are important in attracting flies to flowers, and the pollination syndrome is sapromyophily, in which the flower closely parallels trap flowers of several other plant families, although it is not a trap.

When in doubt, put it in Flacourtiaceae: a molecular phylogenetic analysis based on plastid rbcL DNA sequences

The phylogenetic analysis of plastid rbcL DNA sequences found the family Flacourtiaceae to be composed of two clades that are more closely related to other families in Malpighiales than to each other.

Molecular data place Hydnoraceae with Aristolochiaceae.

Analyses of separate and combined data partitions support the monophyly of Hydnoraceae and the association of that clade with Aristolochiaceae sensu lato (s.l.) (including Lactoridaceae), and a more resolved phylogeny is required to determine whether these represent synapomorphies or independent acquisitions.
