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.

Sengon gall rust (Uromycladium falcatarium)

Sengon gall rust ( Uromycladium falcatarium ) is a species of fungi in Raveneliaceae, grows on molucca albizia ( Falcataria moluccana ) as the host plant, the symptoms vary widely and sometimes are not obvious, the host stem shows brownish lumps to kill slowly. U. falcatarium infects host shoots at the age of 2-3 weeks which causes the leaves to curl, leg, do not develop normally and fall off easily. At 6 weeks of age, symptoms appear on curved and stiff stems and shoots. At the age of 3 months or more the tumor begins to enlarge. Symptoms begin with tumefaction on the leaves, branches and stems. Subsequent development creates a lot of brownish green bumps which then become small rashes on part of the stem or the whole. Kingdom: Fungi Phylum: Basidiomycota Subphylum: Pucciniomycotina Class: Pucciniomycetes Order: Pucciniales Suborder: Raveneliineae Family: Raveneliaceae Genus: Uromycladium Species: Uromycladium falcatarium
