Paleobotany and the Evolution of Plants
The sporangia form a synangium in which the sporangia are fused at their bases
(Fig. 18. 8B). According to Mamay (1950) and Millay (1977), the Chorionopteris-
lype synangium probably represents the primitive type from which sporangia of ...

Frog: An Introduction To Anatomy, Histology And Embryology
The Truncus Arteriosus consists of two parts ; a proximal part or pylangium, which
is a single vessel arising from the ventricle ; and a distal part or synangium, which
consists of the basal parts of the aortic arches closely united together. a.
Stewartiotheca warrenae (Eggert and Rothwell, 1979) are campanulate, 8x10mm
in diameter with up to 80 tubular sporangia in each synangium. The general
arrangement and structural feactures are similar to other permineralized pollen ...

The sporangia are thicker at the base than at the apex, and the whole synangium
or sorus does not taper downwards to pass gradually into the stalk as in the
Whittleseyinae. The whole group was evidently sessile and attached to a disc or
...

Angiosperm Origins: Morphological and Ecological Aspects
The peltae of the latter are rhombic, with a sterile marginal flange that abaxially
shows cyclocytic stomata and is sharply delimited from the fertile central part, the
latter containing a large adaxial synangium of multiple, concentrically arranged, ...

Fossil Plants: A Text-Book for Students of Botany and Geology
The synangium is seated on a very short stalk given off from its sporophyll at the
base of the pair of laminae: the synangium with its short stalk may be spoken of
as the sporangiophore. In most cases the synangium appears to be sessile on
the ...

New Organic Architecture: The Breaking Wave
Each synangium has the same basic organization as the Halletheca organ
except for the smaller number of pollen sacs (four) and reduced size (up to 3.6
mm long). Sporangial dehis- cence takes place toward the hollow center of the
organ.
