The unusual ramification mode of Sphaerothylax abyssinica (Wedd.) Warm. (Podostemaceae - Podostemoideae)
TLDR
Syndesmy sufficiently explains why shoot axes and leaves in Podostemaceae have the appearance of transilient structures without clear demarcations. Expand
Comparative morphology of the vegetative structures of Tristicha trifaria, Indotristicha ramosissima and Dalzellia ceylanica (Podostemaceae, Tristichoideae): a review
TLDR
The discussions herein confirm the view of a general conformity of the morphological features of Indotristicha ramosissima, Tristicha trifaria and Dalzellia ceylanica with common features of angiosperms, and support the applicability of the classical root-shoot model to these plants. Expand
Developmental Morphology of Roots and root-borne shoots ofPodostemum subulatum as compared withZeylanidium olivaceum (Podostemaceae—Podostemoideae) Part VII of the series ‘Morphology of Podostemaceae’
TLDR
The root structure ofPodostemum subulatum is investigated and compared with that ofZeylanidium olivaceum, which appears more advanced than the crustose roots of Zeylanidium, which bear an ordinary (though asymmetrical) root cap. Expand
Shoot apex and spathella: two problematical structures of Podostemaceae–Podostemoideae
TLDR
The presence of a shoot apex and shoot apical meristem (SAM) is confirmed for Marathrum utile and M. foeniculaceum and the view that the spathella is formed by two fused bracts (hypsophylls) is supported. Expand
Dalzellia gracilis: A New Species of Podostemaceae (Tristichoideae) from Kerala, India
TLDR
The establishment of roots and numerous root‐borne shoots that develop into plagiotropously creeping crusts in Dalzellia gracilis links the related but rootless D. ceylanica to the other members of subfamily Tristichoideae. Expand
Embryological and floral studies in Weddellina squamulosa Tul. (Podostemaceae, Tristichoideae)
TLDR
New data favour a re-establishment of the former subfamily Weddellinoideae, as well as the development of the male and female gametophyte, the nucellar plasmodium, embryogenesis and seed structure, which is marked by characteristic deviations from the usual pattern of angiosperms. Expand
Morphology and morphogenesis of ensiform leaves, syndesmy of shoots and an understanding of the thalloid plant body in species of Apinagia, Mourera and Marathrum (Podostemaceae)
TLDR
The results of this study enable an understanding of the particular appearance of these Podostemoideae as modifications of the typical structures according to the ‘principle of variable proportions’. Expand
Podostemaceae Depend on Sticky Biofilms with Respect to Attachment to Rocks in Waterfalls
Investigations of the method by which the plant body of Podostemaceae fastens to naked rocks in waterfalls refute the hitherto accepted existence of a special glue secreted by these plants. Instead,Expand
Crustose root and root-borne shoots of Zeylanidium olivaceum (Podostemaceae - Podostemoideae)
TLDR
The renewed debated nature of the crust (root versus thallus) is clarified and the root nature is evidenced by the existence of a fringe of root cap cells, the presence of an inner meristem, and the endogenous development of secondary (root-borne) shoots. Expand
Comparative studies in the morphology of Crenias weddelliana and Maferria indica with reference to Sphaerothylax abyssinica (Podostemaceae: Podostemoideae)
TLDR
The study highlights intrinsic characters of the widely enigmatic plant body of many species of the subfamily Podostemoideae, which include dorsiventrality of shoots occurring irrespective of gravity, incurvate distichy and one-sided spirodistichy correlated with shoot dorsivENTrality, asymmetric leaves, and several types of positioning of the two prophylls and inflorescence structures.
