Chrysocolla has a cyan (blue-green) color and is a minor ore of copper, having a hardness of 2.5 to 7.0. It is of secondary origin and forms in the oxidation zones of copper ore bodies. Associated minerals are quartz , limonite , azurite , malachite , cuprite , and other secondary copper minerals.
The plant is native but a well-known nuisance in deciduous forests of the eastern U.S. because the seeds can be difficult to remove from clothing and especially pet fur. [8] [9] The seeding part of the plant—the upper stem—dies earlier than most other plants, and becomes very brittle. Often the entire seed stem, or even the entire plant ...
Dioptase is popular with mineral collectors, and it is occasionally cut into small emerald-like gems. Dioptase and chrysocolla are the only relatively common copper silicate minerals. A dioptase gemstone should never be exposed to ultrasonic cleaning or the fragile gem will shatter.
The plant morphologist goes further, and discovers that the spines of cactus also share the same basic structure and development as leaves in other plants, and therefore cactus spines are homologous to leaves as well. This aspect of plant morphology overlaps with the study of plant evolution and paleobotany.
Boquila is a genus of flowering plants in the family Lardizabalaceae, endemic to temperate forests of central and southern Chile and Argentina. It is monotypic, being represented by the single species Boquila trifoliolata, locally known as voqui blanco or pilpil in its native range, [2] and sometimes referred as the chameleon vine since a recent report on leaf mimicry.
The ability of the same AM fungi to colonize many species of plants has ecological implications. Plants of different species can be linked underground to a common mycelial network. [43] One plant may provide the photosynthate carbon for the establishment of the mycelial network that another plant of a different species can utilize for mineral ...
These plants often parasitize alders but they are found on many other plants. Groundcones often look at first glance like pine cones lying on the ground, especially when they are brown in color. They may also be shades of yellow, red, and purple. Each plant may be a few inches tall, and pine-cone-shaped or cylindrical.
Typha latifolia is a perennial herbaceous wetland plant in the genus Typha.It is known in English as bulrush [4] [5] (sometimes as common bulrush [6] to distinguish from other species of Typha), and in American as broadleaf cattail. [7]
