Rhipsalis Neves-armondii
''Rhipsalis'' is a genus of epiphytic flowering plants in the cactus family, typically known as mistletoe cacti. They are found in parts of Central America, the Caribbean and northern regions of South America. They also inhabit isolated locations in Africa and Asia, and are the only cactus group naturally occurring in the Old World. This is the largest and most widely distributed genus of epiphytic cacti (those which live on other plants without damaging them). The scientific name ''Rhipsalis'' derives from the Ancient Greek term for wickerwork, referring to the plants' Morphology (biology), morphology. History The genus was described by Joseph Gaertner in 1788. But when he described the plant, he had in fact not realised it was a cactus. Instead, he assumed he had found a new species of ''Cassytha'',The original spelling in publication is ''cassutha'', but this is presumably a typographical error. a parasitic Lauraceae, laurel from a completely different plant family.

Halimeda
''Halimeda'' is a genus of green macroalgae. The algal body (thallus) is composed of calcified green segments. Calcium carbonate is deposited in its tissues, making it inedible to most herbivores. However one species, '' Halimeda tuna'', was described as pleasant to eat with oil, vinegar, and salt. As in other members of the order Bryopsidales, individual organisms are made up of single multi-nucleate cells. Whole meadows may consist of a single individual alga connected by fine threads running through the substrate. ''Halimeda'' is responsible for distinctive circular deposits in various parts of the Great Barrier Reef on the north-east coast of Queensland, Australia. ''Halimeda'' beds form in the western or lee side of outer shield reefs where flow of nutrient-rich water from the open sea allows them to flourish, and are the most extensive, actively accumulating ''Halimeda'' beds in the world. The genus is one of the best studied examples of cryptic species pairs due to morph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
