| Distribution |
China (Yunnan & Guizhou) up to 2,500 m, Vietnam, Laos and
Myanmar (Burma). |
| Description |
Whole plant only 30 cm. - 60 cm. tall in the "wild" (perhaps
now only in cultivation even in Yunnan) but at least double that in European cultivation
even exceeding 2 m. when well fertilised and grown under heated glass. Plant
suckering more or less freely often producing multiple suckers at a time all opposed to
the same leaf. Pseudostem green with reddish tinges, broad at the base
tapering to a narrow top giving a distinctly conical appearance. In the
"wild" stems sending out at the base a stout horizontal rhizome but this not yet
seen in cultivation in the west and rather suggestive of a prolonged vegetative phase
under impoverished conditions. Leaves
oblong-lanceolate, tip apiculate, about 30 cm. long in the wild but at least double that
in cultivation, held rather stiffly upright giving a "shuttlecock" effect under
good light but held rather lax in shady conditions, glaucous greyish-green with very
narrow reddish-brown margins continued down petiole margin and onto the pseudostem,
narrowed at the base to a petiole one-third the lamina length, more under low light, the
broad, fleshy, truncate bases of the old leaves persisting round the base of the stem,
lamina withering rather rapidly at onset of flowering. Inflorescence long lived, relatively massive, pushing leaves out at
right-angles as it emerges, dense, erect, oblong, somewhat resembling a lotus flower in
bud or a globe artichoke, under 30 cm. long in the "wild" but more in
cultivation ; bracts thin, butter-yellow sometimes with a reddish tinge, persistent, the
upper ovate, the lower ovate-lanceolate. Flowers
yellowish, 4 - 8 in a cluster, above 2.5 cm. long. Calyx
5-lobed. Petal shorter, ovate-oblong. Fruit yellowish, oblong-trigonous, dry, pubescent, with 4 - 6
rounded, black-brown seeds in each cell, which fill up the whole cavity. (Based on Baker 1893 and observations by
drc). |

| Comments |
Reading some material on this plant one might reasonably
suppose it to have been a recent discovery by American botanists. This is not
correct. Known to the Yunnanese since antiquity the plant first came to the
attention of western botanists following its collection in 1885 at 1,200 m. in Yunnan by
the Abbé Delavay (Kew Bull., Add. Ser. 6: 15, 1906).
This taxon has caused and continues to cause problems for taxonomists and its status is
still somewhat controversial.
The
plant was first formally named by A. R. Franchet in 1889 who placed it in the genus Musa
but in a new section he named Musella. Baker (1893) also considered the
plant to be a Musa but placed it in the section Eumusa, as Cheesman
(1947) writes, "presumably because it is described as having a
rhizome, for it has scarcely any other character of Eumusa".
Cheesman examined Delavay's herbarium material at Kew (the type is in Herb. Mus. Paris)
and on the evidence before him commented that "whatever it may
be, it is certainly not a Musa sensu strictiore" and was not
therefore prepared to separate the plant from Ensete. While noting that
further study might find that the plant represented a new genus Cheesman thus created the
combination Ensete lasiocarpum while reviving the genus Ensete in his
1947 paper. The Iconographia Cormophytorum Sinicorum thus gives Ensete
lasiocarpum (A. R. Franchet) E. E. Cheesman as the accepted name of the plant.
Simmonds (1960) disagreed with Cheesman although he
acknowledged that the general appearance of the plant did indeed suggest an Ensete.
Simmonds noted however that the "perianth structure is like
that of Musa" and that the "perianth
characters are critically diagnostic of genus". Although it is clear
that he had not actually seen a living plant Simmonds thus preferred to regard it as a Musa.
Those authors who continue to treat the plant as a Musa e.g. Mabberley 1997 and
the 1999 - 2000 RHS Plant Finder are using Simmonds 1960
as their authority.
Other taxonomists consider the the plant to be an anomaly in both Musa and Ensete
and in 1978 C. Y. Wu (in H.-W. Li 1978) raised Musella to the status of
a separate genus. John Kress at the Smithsonian Institution has (as yet
unpublished) molecular as well as morphological data to support Musella's status
as a distinct, monotypic genus. We await the publication of this definitive work.
The chromosome number of Musella was reported in 1994 by Isobe and Hashimoto to
be 2n = 18; this is the same as Ensete but it is also shared by some Musa
such as M. beccarii. The work of Simmonds and Weatherup suggests, somewhat
counter-intuitively, that chromosome number is not a good basis on which to sort the Musaceae
taxonomically.
Musella
lasiocarpa was recorded first in Yunnan where the local names for the plant translate
as 'yellow lotus emerging from the earth' or 'yellow lotus of the earth mother' or, more
simply, 'rock banana'. The plant is also listed in the Flora of Guizhou as being
from s-e and s-w Guizhou. The plant is cultivated in Fujian and the Mobot Flora of
China website mentions its occurrence, perhaps in cultivation, in Vietnam and Laos.
The occurence of the plant in Vietnam is confirmed by Le Dinh Danh et al 1998 (who rather
oddly did not immediately recognise the plant for what it was) and by Ho Huu Nhi (personal
communication). According to David Bar-Zvi it occurs also in Myanmar (Burma).
Botanists with a working knowledge of Yunnan and Musella think that it may be
extinct in the wild and maintained only in cultivation by farmers. This suggests the
plant has some real economic or symbolic value rather than being purely ornamental.
The plant is said to be cultivated as pig fodder but Roy Lancaster mentions human
consumption in 'Travels in China' (Lancaster 1989).
Lancaster comments that "in October the leafy stems
[of Musella] are sliced into sections and, after boiling to
remove a poisonous principle, are cooked and eaten". In context, it
seems clear that the "leafy stems" referred to by Lancaster are suckers which
develop particularly after flower initiation in autumn. The plant is also grown as
an ornamental in Yunnan e.g. as potted plants in hotel courtyards. There is also a
medicinal use; I have been told by a Chinese contact that the "flower and the juice
of the stem can be used as medicine to stop bleeding etc.".
The Mobot Flora of China Checklist website also gives some
information on this plant:
http://mobot.mobot.org/Pick/Search/foc.html.
Still relatively little known in western horticulture this
plant continues to attract special interest, see for example:
http://www.ftg.org/horticulture/musellalasiocarp.html.
And here is an update about the
plant at Fairchild by David Bar-Zvi.
Musella
is becoming more widely available and as this happens more will be learned about its
horticulture. Raising plants from commercial seed is notoriously difficult either
because of poor viability or complex dormancy requirements or perhaps both. However,
the plant produces spontaneous suckers more or less freely and this phenomenon can be
manipulated for propagation by damaging the vegetative growing point as is done with Ensete.
Tissue culture can also be used to micropropagate the plant. Musella
seems to be adaptable to the climate of Florida as it is to the U.K., is easy to grow,
although spider mites are problematic, and responds well to high-N fertiliser although it
perhaps not so quick growing as, say, Ensete ventricosum.
In Yunnan the plant survives regular frosts but its cold hardiness in cultivation is not
properly known. Reportedly it is hardy to USDA zone 5 or 6.
