Abstract The genus?l(ijJcetiaof Thailandisrevised and 12 species includingfournew species, M. membranaeea, ML ovatistipulata, ML Panieulij2)rmis,^{and Ml siamensis are} enumerated.

The Malayan species M. ianceelataisreduced to a synonym of M, .t?isciculata^of

Java.

^An

artificial kcy to the species isprepared.

Key words:

membranacea, Alycetiaovatistiputata, ?VOcetia

Panicutijbrmis, decetia

^siamensis.

^The genus M]eetia

is

characterized as erect shrub or rarely shrublet,

branch

^with

bark

^soon

becoming pa!e

^{corky or rarely not,}

glandulose bract

and calyx, two- or rarely

more-celled ovary whose placenta

is

swallen and

bears

many ovules,

yellow

^{or rarely}

white corolla, and white

berry.

There are about

30

^species

in Himalayas, South

^and

Southwest China, Continental

Southeast

^{Asia, and Malesia.}

Hitherto five

^species _,of

Myeetia

^{are reported}

from Burma (KuRz ^{1877, CRAm 1911}

& l914),

fbur from Indochina (PiTARD ^1923),

^and

^{fbur from Malaya} (RmLEy ^1923).

In

Thailand CRAiB

(1932)

^{enumerated eight species}

^including

^{one endemic species.}

Recently many specimens were collected

in

this country.
