FLOWERS Beautiful and LOVELY
The flowers are gathered in the spadix, that long part full of carobs that is wrapped in the white sheet (see photo beside). At this stage of flowering water should be watered twice a week, at most three, being careful not to water the flowers.

Abstract Abstract: This article is a stub. You can help Wikipedia by expanding it. . Wide species ranges are especially striking in the reef,Äêrich IndoÄêwest Pacific, the largest and most diverse marine biogeographic region, extending across half the planet. The insular marine biota of the tropical Pacific is characterized by wide-ranging species and provides the most striking examples of long distance dispersal, with endemism largely confined to the most remote island groups. Here we show that the gastropod Astralium, Äúrhodostomum,Äù has developed endemic clades on almost every Pacific archipelago sampled, a unprecedented pattern in marine biogeography, and reminiscent of the terrestrial biota of oceanic islands. Mitochondrial DNA sequences indicate that this species is comprised of at least 30 geographically isolated clades, separated by as little as 180 km. Evidence suggests that such fine scale endemism and high diversity is not exceptional, but likely characterizes a substantial fraction of the reef biota. These results imply that (1) marine speciation can regularly occur over much finer spatial scales than generally accepted, (2) the diversity of coral reefs is even higher than suggested by morphology, estimates, and (3) conservation efforts need to focus at The archipelagic level in the sea as on land.
