Phylogenetic Relationships of Didymocistus and Hymenocardia ( Euphorbiaceae )
The genus Hymenocardia has been placed either in Euphorbiaceae subfamily Phyllanthoideae or in its own family and then associated with the Urticales, particularly the Ulmaceae. However, the pollen exine wall of Hymenocardia lacks the microchanneled tectum, granular interstitium, and thin foot-layer of the Urticales. Hymenocardia instead has many palynological features found in the Phyllanthoide...
متن کاملIn vitro culture of Phyllanthus stipulatus (Euphorbiaceae)
(In vitro culture of Phyllanthus stipulatus (Euphorbiaceae)). An efficient micropropagation protocol was developed for the medicinal plant Phyllanthus stipulatus (Euphorbiaceae) using nodal segments for axillary shoot proliferation. Maximum multiplication rates (8-9 shoots per explant) was achieved on MS media supplemented with either 2.5-5.0 μM IBA. The best basal media for axillary shoot prol...

15 صفحه اولPhylogenetic Implications of Pollen Ultrastructure in the Oldfieldioideae (Euphorbiaceae) Author(s):
The pollen structure of members of Euphorbiaceae subfamilies Oldfieldioideae and Phyllanthoideae was studied using scanning and transmission electron microscopy in order to assess taxonomic relationships. We identified 10 palynological characters that appear to have systematic significance. We also identified 37 characters of vegetative morphology and anatomy, mostly based on data obtained by H...
