Field studies in the Lamagetou Nature Reserve,
Mianning Xian, Sichuan Province, in the summer of
2005 revealed aparticularly rich and diverse flora . The
vegetation in the area comprises thickets and forests of
mixed shrubs ( Salix, Lonicera, Rhododendron) and
trees ( Abies, Picea, Acer, Prunus) in ravines andon
mountain slopes and interspersed meadow-shrub clear-
ings on broader, more level sites . One particularly
noteworthy plant growing in openings in the forest, at
woodland margins and on exposed slopes was the re-
cently described Meconopsis wilsonii Grey-Wilson sub-
sp. wilsonii (Papaveraceae) (Grey-Wilson, 2006) . The
last and only other collectionof M. wilsonii subsp. wils-
onii was made nearly 100 years ago, in 1908 . Because
of the wide horticultural and taxonomic interests in
Meconopsiswewish to make our discovery known .
Meconopsis wilsonii had previously been included
within a widespread and highly diverse M. napaulensis
until Grey-Wilson′s ( 2006 ) careful study brought to
light thedifferences that separate thevarious elements .
Meconopsis napaulensis is restricted to central Nepal
and most conspicuously differs from M. wilsonii by hav-
ingyellow petals; Grey-Wilson ( 2006) reports M. wil-
sonii to have“ flowers wine-purple to purple or crim-
son .”Our collections were recorded as having bluish
purple petals .
Meconopsis wilsonii comprises two subspecies,
which are separated by Grey-Wilson ( 2006) using the
following key characters:
Basal and lower leaveswith6 - 8 pairs of primary segments, mid-
dle and upper cauline leaves and bracts deeply divided, with6 -
8 pairs of segments; hairs of peduncle and pedicel ascending to
subappressed (Sichuan plants)
subsp . wilsonii (Figs . 1 - 3)⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯
Basal and lower leaves with 4 or 5 pairs of primary segments,
middle and upper cauline leaves and bracts shallowly divided,
with 3 - 5 pairs of segments; hairs of peduncleand pedicel patent
(plants of Yunnan and Myanmar)
subsp . australis (Figs . 4 - 6)⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯⋯
Grey-Wilson′s description of Meconopsis wilsonii ,
with which we agree, states“ . . . generally a large and
rather coarseplantwithhandsomerather greyishor bluish-
green leaf rosettes . It isvery distinctive in flower with its
erect to sharply ascending, rather short branches which
give thewhole inflorescence a narrow‘fastigiate’appear-
ance .”He (Grey-Wilson, 2006) further states that the
species is theonly member of subsection Eupolychaetia to
be found inChina . Meconopsiswilsonii exhibits adisjunct
distribution, with subsp. wilsonii restricted towestern Si-
chuan and subsp. australis occurring in western Yunnan
andnorthernmost Myanmar .Subspecies australishasbeen
collected a number of times, but subspecies wilsonii was
known only fromthe typespecimens collected in 1908, in
Sichuan, south of Moupin (nowBaoxing) .
