Abstract

Plectranthus monostachyus (P. Beauv.) B. J. Pollard yang dikoleksi dari Dramaga-Bogor dan Jatinangor-Sumedang merupakan rekaman baru untuk marga Plectranthus di Pulau Jawa. Keberadaannya di Jawa belum dicatat oleh Backer (Flora of Java Vol. II, 1965: 635─636) dan Keng (Flora Malesiana Vol. 8 (3), 1978: 382─393). Jenis tersebut merupakan tumbuhan asli dari kawasan Afrika Tropis dan banyak ternaturalisasi di luar daerah sebaran aslinya. Chung et al. (dalam Nature in Singapore 8: 1–13. 2015) melaporkan bahwa P. monostachyus pertama kali direkam di Singapura pada tahun 2009 dan saat ini telah tersebar secara luas di pulau tersebut. Pada lokasi pengamatan di Dramaga dan Jatinangor, jenis ini tumbuh di area persawahan, sepanjang aliran air, dan daerah yang ternaungi. Penyebaran bijinya diduga dibantu oleh air. Plectranthus monostachyus dipertelakan sebagai berikut.

Abstract

Mayacaceae Kunth is a monogeneric family with a single genus, Mayaca Aubl. Its family members are herbs found in swamps, lakes, and rivers. The family is distributed throughout the Neotropics, except for M. baumii Gürke, which is only found in Africa [de Carvalho MLS & Machado AFP., Revisiting Mayacaceae Kunth towards to future perspectives in the family, Rodriguésia 66(2): 421-427. 2015]. Mayacaceae consists of ten species and one of them, Mayaca fluviatilis Aubl. is widely cultivated as an aquascape ornamental plant, including in Indonesia. This aquatic family is not yet recorded in the Flora of Java Vol. III [Backer CA & Bakhuizen van den Brink RC., Flora of Java, Vol. III, Groningen: NVP Noordhoff. 1968].
