Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...

Kaliandra (Calliandra houstoniana)

Kaliandra ( Calliandra houstoniana ) is a plant species in Fabaceae, grows rapidly to 2.5-3.5 m tall in 6 months and 3-5 m high in the first year with a 60% light quantity, widely used for energy wood, animal feed, erosion control, soil nitrogen repair, fire retardant, shade and source of nectar for bees. C. houstoniana grows to a maximum of 12 m and a stem diameter of 20 cm, red or gray bark covered by small, pale oval-shaped lenticels. Increasingly to the tip of the stem tends to jagged and reddish brown stems have a red tip. Taproot system is supported by finer roots with very large numbers and extends beyond the soil surface. The leaves are small, compounded pairs, soft texture and dark green, 20 cm long, 15 cm wide and at night will fold toward the trunk by the motion of the dictation due to changes in light to dark. The canopy widens to the side and is very dense. Flower bunches develop in a centralized position and flowers cluster around the end of the stem with threads gen...

Gualaquiza hanging flower (Ceratostema gualaquizensis) from Ecuador is new to science, similar to Ceratostema pendens

NEWS - Gualaquiza hanging flower ( Ceratostema gualaquizensis M.M.Jiménez & H.Garzón, sp. nov.) from southern Ecuador is reported as a species new to science as part of an ongoing study of the biodiversity of the Cordillera Real de Los Andes. Ceratostema Jussieu (1789) includes 35 known species of which 2 are native to Colombia, 3 from Peru, 1 from Venezuela-Guayana and 32 in Ecuador of which 26 are endemic. The species are mostly restricted to the eastern montane forests of the Ecuadorian Andes. Ceratostema are terrestrial or epiphytic, but sometimes grow as dwarf shrubs and often exhibit lignotubers. The genus is characterized by flower stalks that are mostly articulated to the calyx; flowers with large, thick corollas and elongated lobes; long stamens; coarse anthers and elongated tubules. C. gualaquizensis are pendant epiphytic shrubs; indumentum consisting of short, white, almost persistent, eglandular trichomes of 0.2–0.9 mm long, trichomes arranged unevenly, sparsely to de...
