Sirih keraton or keraton pepper (Piper bandoro) and a name

Keraton pepper (Piper bandoro) in Indonesia is called Sirih Keraton, this is a rare species and there is no information on taxonomic nomenclature. So I named and entered as a new species.

Sirih keraton (P. bandoro) is different to Piper ornatum and Piper crocatum as the closest species, although they have similarities in other parts. The key differences are the morphology and features of the leaves. You can read the taxonomic nomenclature here: https://www.dlium.com/2020/01/keraton-pepper-piper-bandoro.html

I found keraton pepper at several sites in Menoreh mountains. I first saw at Samigaluh and Kokap in Kulon Progo, this in Yogyakarta Province. Then I found it again at Kaligesing in Purworejo, Central Java Province.

Menoreh mountains have complex landscape, topography is hilly to elevation of 50 m to 1050 m. This is ancient volcano and is routinely fogged on this day. I found Piper bandoro at several sites at height of 300 m to 800 m. You can see on Google Map: https://goo.gl/maps/K…

Cacao tree (Theobroma cacao)

Kakao or cacao tree (Theobroma cacao) is a perennial plant species in Malvaceae in the tropics, in the form of a tree 10 m high but in cultivation it will be limited to only 5 m to expand the canopy and multiply branches so that more fruit grows where the seeds are processed as chocolate.

T. cacao has flowers like other Sterculiaceae members that grow directly from the stem, perfect and single flowers, 3 cm in diameter, but appear in panicles because often a bunch of flowers emerges from a single bud.

The flowers are white and are ready to be pollinated within a few days especially by the Forcipomyia fly, winged ants, aphids and some Trigona bees which usually occur at night. The main pests of this plant are Bactrocera carambolae and Bactrocera papayae.

Cacao trees generally cross-pollinate and have their own incompatibilities, but some varieties are capable of self-pollinating and produce higher-selling commodity types.

The fruit grows from pollinated flowers, has a fruit size much la…
