2 THE SPECIES
Veitch (James Veitch & Sons, Manual of Orchidaceous Plants, published around 1890) notes this species was first described in 1844. Hawkes (Alex D. Hawkes, Encyclopaedia of Cultivated Orchids), notes this plant produces somewhat cylindric pseudobulbs which are some 125 - 150 mm tall, clustered together, and which become furrowed with age. Its wide plicate leaves are deciduous over time, from 450 to 600 mm long, and are prominently folded. Single flowered inflorescences are produced, usually several at any one time, which are 300 mm tall. The flowers produce a heavy medicinal fragrance, are very waxy, bright golden yellow in colour. There is, as occurs in all the species, a complex hinged lip. Spring - summer flowering, it is native of Colombia and Venezuela. The plant is very similar in structure to ruckeri, its major distiction being its very different colouration.
Hawkes notes there are a number of colour variants, the most important he lists being var. ebumea, described as being extremely rare. This is ivory/white in colour, but "The same as the typical form in every other way". Williams notes this is "a magnificent plant". Kennedy1 states that all the plants he has seen labelled ebumea have been referable to the species uniflora or virginalis. Perhaps this is why it is so rare!!
Of all the Anguloa species clowesii has been the most widely used and the most successful in breeding.
Originally it was called cliftoni but was quickly corrected to clitfonii
Kennedy notes the lip of clowesii and cliftoni are distinct, the lips of all three yellow anguloas illustrated here in their flattened form
Oakeley states this is a very rare endemic Colombian species, showing pale yellow petals and sepals, sparsely spotted red. Oakley also notes the artificial hybrid uniflora x closesii bearing the hybrid grex name of Ang dubia shows no resemblance to this species, the cross requiring a new name in the Sander's List of Orchid Hybrids.
