Temu Bosuang (Boesenbergia bosuangii), Temu Gana-gana (Boesenbergia ganaensis) and Temu Gokusing (Boesenbergia gokusingii)

NEWS - Researchers from the University of Malaya in Kuala Lumpur, the Forest Research Institute Malaysia in Kepong and the Royal Botanic Garden in Edinburgh have identified three new species, Temu Bosuang (Boesenbergia bosuangii), Temu Gana-gana (Boesenbergia ganaensis) and Temu Gokusing (Boesenbergia gokusingii).

B. bosuangii is similar to B. stenophylla R.M.Sm. in its narrow-oval lamina but differs in the shape of its bract and calyx. The species is endemic to Borneo, Sabah. The specific epithet is given by Dr Steven Bosuang, owner of Kipandi Park, an entomologist who works on insect and plant conservation in Sabah.

The new species grows in riverine areas in mixed dipterocarp forests at elevations of 50-300 metres and flowers in August. The researchers have proposed the status Vulnerable VU D1 due to its small population, limited space outside protected areas and potential threats from development, landslides and flooding.

B. ganaensis is closely related to B. burttiana R.M.Sm. but differs in the absence of ligule, longer petiole, blunt leaf base, pointed leaf tip, bilobed calyx and anthers peeled off by pores. This species is endemic to Kalimantan, Sabah.

The specific epithet refers to the location where the species was collected in Kampung Gana-gana, Ranau. This plant grows in granite areas at an elevation of 500-600 meters. The researchers proposed the conservation status Vulnerable (VU D2) because there are only four populations at the type site.

B. gokusingii is similar to B. variegata R.M.Sm., in that it has single-leafed shoots but differs in having unequal oblong laminae, heart-shaped leaf base, pointed leaf tip and anthers peeled off by pores. This species is endemic to Kalimantan, Sabah.

The specific epithet is based on Mr. Linus Gokusing from Kipandi Park who collected this plant in 2011. His passion for plants has provided useful information to the public. This species is in mixed dipterocarp forest at an elevation of 500-600 meters. Vulnerable status (VU D2) because it is only in the type location with 3-6 populations in each location.

Green-spored parasol (Chlorophyllum molybdites)

Green-spored parasol or false parasol ( Chlorophyllum molybdites ) is a species of fungus in Agaricaceae, has a large size, umbrella canopy, ringed pillar, dominant white color, grows widely spread in various latitudes, is poisonous and produces severe gastrointestinal symptoms in the form of vomiting and diarrhea. C. molybdites has a diameter of pileus up to 40 cm, sponges, round, flat top, convex or concave, whitish color with coarse brownish scales. The gills are white and will turn dark and green as they mature. Stipe has a height of up to 25 cm and has a ring. Green-spored parasols have green spores, thrive on manure in the yard and park, are solitary or crammed into an area, often arising from between the grasses in temperate, subtropical and tropical highlands throughout the world. C. molybdites is a poisonous fungus that is most often eaten by similarity to other agricultural fungi. Symptoms of poisoning come 1-3 hours after consumption, most of which are gastrointestinal w...

Plumeria rubra and Plumeria obtusa, the differences

SPECIES HEAD TO HEAD - The genus frangipani trees ( Plumeria Tourn. ex L.) has only 18 officially recorded species and two very similar species, frangipani ( Plumeria rubra L.) and white frangipani ( Plumeria obtusa L.). Both have the same habitus, flowers and fruits and are difficult to distinguish. The leaves of both species have slightly different shapes. Therefore, the leaves are very important to distinguish the two species, especially the shape of the tip. P. rubra has simple, lanceolate leaves with acute tips. P. obtusa has simple, elliptic leaves with rounded tips. By Aryo Bandoro Founder of Dlium.com . You can follow him on X: @Abandoro . Read more: Plumeria rubra Plumeria obtusa
