Ourisia Spathulata
''Ourisia spathulata'' is a species of flowering plant in the family Plantaginaceae that is endemic to high-elevation habitats in Southland on the South Island of New Zealand. Mary Kalin Arroyo described ''O. spathulata'' in 1984. Plants of this species of New Zealand mountain foxglove are perennial, small-leaved herbs that are covered in a mixture of glandular and non-glandular hairs. They have velvety, hairy, crenate, spathulate leaves that are oppositely arranged and tightly packed along the creeping stem. The flowers are single or in pairs in each node, with a zygomorphic calyx and corolla. The corolla is white and the corolla tube is glabrous and yellow inside. It is listed as At Risk - Naturally Uncommon. Taxonomy ''Ourisia spathulata'' Arroyo is in the plant family Plantaginaceae. Mary Kalin Arroyo described ''O. confertifolia'' in 1984. The type material was collected by David Given in the Eyre Mountains, Southland, South Island, New Zealand. The holotype is ho ...

Mary Kalin Arroyo
Dr. Mary Therese Kalin-Arroyo was born in 1944 in New Zealand. She is currently a professor of biology at the University of Chile. Kalin-Arroyo is notable for revising the indigenous genus ''Ourisia'' and discovering several new species in New Zealand. Her studies have also led to the designation of central Chile as a biodiversity hotspot. Early life and education She earned her BSc honors degree at the University of Canterbury in Christchurch, New Zealand in graduating with first class honours in 1967. She then completed her Ph.D in Botany from UC Berkeley in 1971. The following year, Kalin-Arroyo did a post-doctoral with Peter Raven at the New York Botanical Garden. In 1978, she married her husband Manuel Arroyo and together with their son, moved to the University of Chile where she would work as an associate professor. Dr. Kalin-Arroyo would later become a full professor in 1984. Currently, she is the director of the Institute for Ecology and Biodiversity at the University ...

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ourisia Confertifolia
''Ourisia confertifolia'' is a species of flowering plant in the family Plantaginaceae that is endemic to high-elevations in the southern South Island of New Zealand. Mary Kalin Arroyo described ''O. confertifolia'' in 1984. Plants of this species of New Zealand mountain foxglove are Perennial plant, perennial, small-leaved rosette herbs that have hairy, crenate leaves, and flowers single or in pairs in each node. The corolla tube is glabrous and yellow inside. It is listed as At Risk - Naturally Uncommon. Taxonomy ''Ourisia confertifolia'' Arroyo is in the plant family Plantaginaceae. Mary Kalin Arroyo described ''O. confertifolia'' 1984. The type material was collected by Mary Kalin Arroyo at Gertrude Saddle, Fiordland National Park, South Island, New Zealand. The holotype is housed at the Allan Herbarium of Manaaki Whenua – Landcare Research. ''Ourisia confertifolia'' is morphologically similar to other New Zealand small-leaved species, namely ''O. sessilifolia, O. si ...
