how is Brassia and Comesperma connected?
Comesperma Comesperma is a genus of shrubs, herbs and lianas in the family Polygalaceae. The genus is endemic to Australia. It was defined by the French botanist Jacques Labillardière in his 1806 work "Novae Hollandiae Plantarum Specimen". The genus name is derived from the Ancient Greek words "come" ("hair") and "sperma" ("seed"), and relates to the seeds bearing tufts of hair. The genus is distributed over southern Australia, particularly in the southwest of Western Australia, where 19 species are found. 24 species have been described.
Acetabularia Acetabularia is a genus of green algae, specifically of the Polyphysaceae family, Typically found in subtropical waters, "Acetabularia" is a single-celled organism, but gigantic in size and complex in form, making it an excellent model organism for studying cell biology. In form, the mature "Acetabularia" resembles the round leaves of a nasturtium, is 0.5 to 10 cm tall and has three anatomical parts: a bottom rhizoid that resembles a set of short roots; a long stalk in the middle; and a top umbrella of branches that may fuse into a cap. The single nucleus of "Acetabularia" is located in the rhizoid, and allows the cell to regenerate completely if its cap is removed. The caps of two "Acetabularia" may also be exchanged, even from two different species. In addition, if a piece of the stem is removed, with no access to the nucleus in the rhizoid, this isolated stem piece will also grow a new cap.
