of the late Consul F. C. Lehmann, a dried flower stated 
to be from Yarumal, in the province of Antioquia. The 
material for our figure of O. chiriquense has been derived 
from a plant acquired for the Kew collection at the Red 
Cross sale held in 1916. Until then this plant had been 
for upwards of twenty years in the collection of Mr. W.G. 
Grove, Holehird, Windermere. At Kew it flowered in 
October. It thrives well in a house suitable for species 
of Miltonia, the Odontoglossum house being too cold in 
winter for this species. It makes vigorous growth in a 
compost of peat fibre and sphagnum and requires a 
liberal supply of water. The nearest ally of O. chiriquense 
is O. coronarium, Lindl., figured at t. 7687 of this work, 
of which it has been regarded as a variety, but from 
which it is readily distinguished by its larger and very 
undulate flowers.
