Cirrhopetalum tseanum S.
Y. Hu & Barretto
We are very grateful to Peter Taylor, and his associate,
J. Wood, who spent many hours going through the literature and
collections at Kew, on the identification of this species. The
conclusion they reached is that the orchid appears to be undescribed.
Their view is that it is closely related to Bulbophyllum
morotaiense J. J. Smith, on floral characters, but this
species has smaller leaves and is from the Moluccas. In addition
to geographical separation, the floral parts of the two species
differ proportionately. In Smith's species the odd sepal is
7-8 mm. long, and the lateral sepals are 13-17 mm. long, while
in C. tseanum the odd sepal is 5 mm. long, and the
lateral sepals are 18-20 mm. long.
This orchid was discovered in 1974 and transplanted to his garden
by Tse Shing Chee. It flowered in March this year. It is named
for its discoverer.
