Description
Family Melastomataceae
Herbs, shrubs
, or trees
(to 20 m
tall), erect
, climbing
, or rarely epiphytic. Stipules lacking. Leaves simple
, commonly opposite and decussate with one of a pair slightly smaller than other, rarely verticillate
or alternate by abortion
of one of a pair, usually 1-4(or 5) secondary veins on each side of midvein
, originating at or near base
and anastomosing apically, tertiary veins numerous, parallel, and connecting secondary veins and midvein but in Memecylon secondary veins pinnate and tertiary veins reticulate
. Inflorescences cymose
, umbellate
, corymbose
, in paniculate
clusters
, or a cincinnus, rarely flowers single, fascicled, or born on a spike; bracts sometimes conspicuous
and persistent
. Flowers bisexual
, actinomorphic
but androecium often slightly zygomorphic, usually (3 or) 4- or 5(or 6) -merous, perianth biseriate
, perigynous; bracteoles opposite, usually caducous
. Hypanthium funnel-shaped, campanulate
, cyathiform
, or urceolate
. Calyx lobes
(3-) 5(or 6), valvate
(rarely connate
, but not in Chinese species) . Petals (3-) 5(or 6), equal to number of sepals, distinct
, imbricate. Stamens usually twice as many as petals and in 2 whorls, rarely as many as petals by loss of 1 whorl, isomorphic
or dimorphic
; filaments
distinct, often geniculate
, inflexed
in bud; anthers
typically 2-celled, introrse
, basifixed
, dehiscent
by 1 or 2 apical pores
or by short longitudinal
slits (Astronia, Memecylon) ; connective
often variously appendaged. Pistil and style 1; stigma minute, capitate or truncate
. Ovary commonly inferior or semi-inferior, locules usually (3 or) 4 or 5(or 6) with numerous
anatropous ovules
, rarely 1-loculed and ovules ca.
9 (Memecylon) ; placentation axillary
, parietal
(Astronia and, outside China, Pternandra Jack
), or free
central (Memecylon) . Fruit a dry or fleshy
capsule or a berry, loculicidally dehiscent or indehiscent. Seeds (when 3-6-loculed) usually small, curved
through half a circle (cochleate) or wedge-shaped (cuneate), in Memecylon seeds large and ovoid
; endosperm absent.
Between 156 and 166 genera (150-160 in Melastomataceae sensu stricto
and six in Memecylaceae here considered part of Melastomataceae) and ca. 4500 species (ca. 4050 in Melastomataceae sensu stricto and 450 in Memecylaceae [Olisbeoideae if considered a subfamily
of Melastomataceae]) : primarily in tropical
and subtropical
regions; 21 genera (five endemic) and 114 species (72 endemic) in China.
Chinese genera of economic value include Osbeckia (medicine) and Melastoma (wild fruit and ornamental
flowers) .[1]
