When Pseudoasterophyllites was added to the J/M tree, where Chloranthaceae and Ceratophyllum are well separated, its most parsimonious position was sister to Chloranthaceae, supported by opposite or whorled leaves, stephanocytic stomata, sessile,
unisexual flowers, one stamen, embedded pollen sacs, supratectal spinules, one carpel, and orthotropous ovule, but a position with Ceratophyllum was only one step less parsimonious.

Flies predominated on all traps (91% of all collected insects), morpho-species 1 (Lauxaniidae, about 3 mm in length) being the most abundant captured insect (48.4% of all insects on bisexual coenanthia and 52.7% of those on
unisexual male coenanthia; Table 2).

Rydgren K, Halvorsen R and Cronberg N (2010) Infrequent sporophyte production maintains a female-biased sex ratio in the
unisexual clonal moss Hylocomium splendens.
Flowers 1-1.5 cm long, sessile, bisexual or
unisexual, corolla 4-6-merous; stamens wider than their length, filament with depression accommodating anthers which are basifixed.
Flowers are small, much branched,
unisexual in tomentose, druping, and axillary panicles in the upper axils.
It is presumed that the
unisexual flowers and sexual dimorphism represent derived conditions in palms (Moore and Uhl.
The vines produce
unisexual flowers--that is, either male or female flowers as opposed to bisexual or perfect flowers like a lily or rose.
The plant is
unisexual, a strong climber with grayish fruits and edible seeds that are smooth and also have hard seed testa (schippers 2000).
