Novelties in Myanmar Umbelliferae: a new species of Oenanthe L. and two new floristic records

Michael G. Pimenov

Botanical Garden, Lomonosov Moscow State University, Moscow, Russia

Oenanthe hortorum-natantium is described and illustrated as a new species, endemic to Myanmar (former Burma). It differs from closely related species of sect. Dasyloma in dissection of leaf laminas, and the form of terminal leaf segments, as well as some characters of lifeform. Two other Umbels species, widely distributed in tropical and subtropical regions, Hydrocotyle verticillata and Cyclospermum leptophylum had been recorded for Myanmar flora for the first time.

Пименов М.Г. Новинки Umbelliferae Мьянмы – новый вид Oenanthe и две новые флористические находки. Описан и иллюстритован новый вид Oenanthe hortorum-natantium, эндемичный для Мьянмы (бывшая Бирма). Он отличается от близких видов секции Dasyloma рассечением пластинок листьев и формой конечных листовых сегментов, а также особенностями жизненной формы. Два других вида зонтичных, Hydrocotyle verticillata и Cyclospermum leptophyllum, впервые указанные для Мьянмы, широко распространены в тропиках и субтропиках.
