Abstract
Amomum fulviceps Thwaites is correctly identified for the first time from India. Previous record regarding
the occurrence of the species is discussed. Detailed description, illustration, photographs, distributional and
ecological details are provided.
Keywords: Amomum fulviceps, Zingiberaceae, New Record, India
Introduction
Amomum Roxb. is the second largest genus of the
family Zingiberaceae (Tripathi & Prakash, 1999).
The first account on Amomum was given by Roxburgh (1820). Baker (1892) recorded 12 species of
Amomum from Indian subcontinent. Subsequently
Karthikeyan et al. (1989) enumerated 14 species
and Jain & Prakash (1995) 16 species from India.
Since Baker, 5 new species, viz. A. deorianum D. P.
& N. Dam, A. jainii S. Tripathi & V. Prakash, A.
garoense S. Tripathi & V. Prakash, A. ghaticum
K. G. Bhat and A. vermanum S. Tripathi &
V. Prakash have been added to this genus. The first
description of A. fulviceps was given by Thwaites
(1864), followed by Baker (1892) and Trimen (1898)
from Ceylon (Sri Lanka). Thwaites described two
variations of A. fulviceps – one with glabrous leaves
collected from Raxawa in Central Province (C. P.
3122) and another with hairy leaves collected from
Reigam Corle (C. P. 3704). Baker (1892) established
a new species named A. ciliatum based on the specimen C. P. 3704. Fischer (1928) reported 5 species of
Amomum including an endemic from South India
of which one species has been transferred to Alpinia
thus reducing the number of species to four. Mitra
(1958) reported 8 species of Amomum from Eastern
India. Rao & Verma (1972) reported 5 taxa including one variety from Assam. Bhat (1988) added
A. ghaticum, a new species and A. masticatorium
Thwaites, a new record for India. Recently, Sabu
(2006) dealt 6 species for South India.
Panigrahi & Naik (1966) reported the occurrence
of A. fulviceps Thwaites in Northeast India based
on an earlier collection (Meghalaya, Khasia &
Q020-Rheedea-080901_CH003.indd 13
Jaintia Hills, Dawki forest, 27.4.1940, R. N. De 20322
(ASSAM)). After critical study of the specimen it
has been identified as A. deorianum, a new species
established by Dam & Dam (1992) based on the collections from East of Dawki (Meghalaya, Khasia &
Jaintia Hills, East of Dawki, 22.4.1972, N. C. Deori
51696 (ASSAM)). The common characters such as
pale yellow flowers, red-coloured bracts, trilobed
labellum and hairy nature of bracts must have led
to the wrong identification.
During recent explorations in Agasthyamala Hills
of Western Ghats (Kerala), A. fulviceps has been
collected and it forms a new addition to the Zingiberaceae flora of India. Its identity has been confirmed by comparing it with the photograph of
type specimen obtained from National Herbarium,
Paradeniya (PDA), Sri Lanka. Detailed description, distribution, ecology, etc. along with illustration and photographs are provided to facilitate its
easy identification.

Flowering & Fruiting: February – April.
Distribution: India and Sri Lanka; in India, this species
is reported only from Agasthyamala Hills of Kerala.
Ecology: Plants growing in deep evergreen forests
at an altitude between 1200 and 2000 m.
Notes: The species can be easily distinguished from
other Amomum spp. by red-coloured bracts, pale
yellow flowers with trilobed lip, semi-lunar anther
crest, yellow-brown indumentum when dry and
echinate red capsule. However, descriptions given
by Burtt & Smith (1983) has 2-lobed calyx instead
of three lobed, corolla lobes flushed with brownish
red on middle of back (here colouration only near
lower part of corolla tube) deep yellow lip instead
of pale yellow and slight changes in size. But the
specimens match with the type and protologue.
Etymology: The specific epithet ‘fulviceps’ derived
from a Latin word ‘fulvous’ means yellow-brown
(tawny) indicates the presence of yellow-browncoloured hairs on surface of bracts, bracteole, calyx
and ovary.
