Zingiberaceae, J.M.Lock. Flora of Tropical East Africa. 1985

Habit
Perennial herbs, usually with creeping rhizomes; usually terrestrial but occasionally (not in East Africa) epiphytic; sterile and fertile shoots often separate, usually unbranched All parts are glabrous, or hairy with simple (rarely stellate) unicellular hairs (bicellular in >i>Costus)
General
Vegetative parts with oil cells (except in Costus) and aromatic
Leaves
Leaves solitary at the nodes or occasionally crowded at the base of the stem, alternate and 2-rowed, or (>i>Costus) in an open spiral, consisting of sheath, ligule and lamina; sheaths encircling the stem, sometimes forming a pseudostem, with the margins free or joined; ligule adaxial, often bilobed, sometimes (>i>Costus) encircling the stem and then often called an ochrea; lamina usually narrowly elliptic, narrowing into a short false petiole, with a strong median nerve and parallel laterals which diverge from the midrib at about 45° (in >i>Costus the laterals are themselves joined by parallel tertiary veins)
Inflorescences
Inflorescences racemose (spikes, panicles and racemes occur); bracts and bracteoles (if present) usually large and conspicuous, sometimes coloured
Flowers
Flowers (hermaphrodite, strongly zygomorphic, 3-merous
Calyx
Calyx tubular or spathaceous, often 3-lobed at the apex, valvate
Corolla
Petals 3, equal or unequal, fused at the base with the androecium to form a perianth-tube, imbricate in bud
Androecium
Androecium composed of a single, often petaloid stamen, with anther-thecae dehiscing by longitudinal slits, and a large petaloid variously lobed member, the labellum, formed from 2 fused staminodes (filamentous outgrowths at the base of the stamen are sometimes claimed to represent other staminodes; in >i>Costus 5 staminodes are believed to be involved in the formation of the labellum)
Gynoecium
Ovary inferior, 3-locular, with axile placentation and usually numerous ovules; style and stigma one
Nectaries
Nectaries of various forms occur either beside the style-base (those which are paired and elongated have often been called stylodia), or embedded in the top of the ovary
Fruits
Fruit a berry or capsule, often large and with thick fleshy walls, usually black or red when ripe; sometimes subterranean
Seeds
Seeds surrounded by a fimbriate aril, usually smooth and hard, with abundant endosperm

Morphology
Description

Perennial often large-sized, aromatic herbs, with rhizomes; indument composed of simple to stellate hairs. Stems terete , straight. Leaves alternate , distichous , with open sheaths and a very small, truncate ligule . Inflorescence generally a terminal panicle , mostly on a separate leafless shoot ; bracts mostly herbaceous to membranous , often soon falling off, each subtending 1-10 flowers; bracteole herbaceous , tubular and closed before anthesis, sometimes cup-shaped and open even before anthesis. Flowers zygomorphic ; calyx tubular, turbinate , or urceolate, 3- lobed ; petals 3, connate into a distinct tube; fertile stamen 1, with a very short filament , anther 1; labellum equaling the corolla , basal part narrowed, with 2 minute tooth-like lateral staminodes, apical part 3- lobed , tubular or horizontally spreading; style 1, filiform , lying close to the stamen and embraced by the thecae, stigma 1, cup-shaped; ovary inferior, 3-locular, with nectarial glands around the base of the style , placentation axile , ovules many, anatropous. Fruit an often red to black capsule , 3-locular, mostly crowned by the persistent calyx , longitudinally and loculicidally dehiscent . Seeds many, ellipsoid , with a large, yellow, orange, or white aril , glossy brown.

General Description
Notes on delimitation
  • Zingiberaceae belong to the order of Zingiberales. Neotropical Zingiberaceae can be distinguished from all other families in this order by being aromatic and in having an indument often composed of stellate hairs.
Status
  • Aframomum K.Schum. - cultivated.
  • Alpinia Roxb. - cultivated.
  • Boesenbergia Kuntze - cultivated.
  • Curcuma L. - cultivated and sometimes naturalized (C. xanthorrhiza).
  • Etlingera Giseke - cultivated.
  • Hedychium J.Koenig - cultivated, but often naturalized (H. coronarium).
  • Kaempferia L. - cultivated.
  • Renealmia - Native.
  • Zingiber Boehm. - cultivated.
Number of genera
  • 1 genus: Renealmia (60 spp.).
General notes
  • Aframomum melegueta K.Schum. is cultivated in the Guianas for its spicy fruit.
  • Several species of Curcuma and Zingiber are cultivated for their spicy rhizomes.
  • Hedychium coronarium J.Koenig is naturalized all over the Neotropics, and in the Andes it is even a pest, replacing the original vegetation along roads.
  • The other genera are cultivated as ornamentals, 2 important species being Alpinia purpurata K.Schum. and Etlingera elatior (Jack) R.M. Sm.
Distribution
Distribution in the Neotropics

Family:  from Mexico in the North to Bolivia and S Brazil in the South, also present in the West Indian Islands.

  • Renealmia L.f. is the only native genus in the Neotropics.
Diagnostic
Distinguishing characters (always present)
  • Aromatic herbs.
  • Indument composed of simple to stellate hairs.
  • Leaves distichous, with a very small, truncateligule and an open sheath.
  • Inflorescence generally a bracteate panicle.
  • Flowers zygomorphic.
  • Stamen 1.
  • Labellum more or less the same size as the petals, basal part narrowed, apical part tubular to spreading.
  • Fruit a capsule, 3-locular, mostly crowned by the persistentcalyx, longitudinally and loculicidally dehiscent.
Key differences from similar families

Zingiberaceae differ from Costaceae in having:

  • Aromatic leaves.
  • Open leaf sheaths.
Other important characters
  • Leaf sheaths striate to reticulate or sometimes smooth, often beset with minute stellate hairs.
  • Inflorescence generally a panicle, but sometimes a raceme or spike, sometimes terminal on a leafy shoot.
  • In several species the basalinflorescence trails on the ground.

Habit
Perennial herbs, usually aromatic, with horizontal tuberous rhizomes; stems sometimes very short, leafy or bearing only flowers

Perianth
Perianth 6-merous, 2-seriate, the outer calyx-like, the inner corolla-like and often very showy and delicate; outer segments united into a tube, inner more or less united, the posterior segment usually the largest
Androecium
Stamen 1, with a 2-locular anther, sometimes accompanied by petaloid staminodes which may form the conspicuous part of the flower (see Fig. 341)
Gynoecium
Ovules mostly numerous Ovary inferior, (2-)3-celled with axile placentas, or 1-locular with parietal or rarely basal placentas; style sometimes enveloped in a groove of the fertile stamen
Fruits
Fruit fleshy and indehiscent or a capsule
