perfect agreement in all essentials of structure. The 
chief differences are, the greater luxuriance of the cul- 
tivated specimen, its more numerous suberect, oblanceolate 
bright green leaves, its reticulated sheaths on the brown 
stem, its pale lilac sepals and petals; also the spur of 
its posticous sepal is rather longer and narrower, and the 
lamina is quite entire. The species is referred to the 
section Coryphxa, both by Lindley and Bolus, in which 
there should be two glands of the pollinia, whereas a 
single 2-lobed one is (correctly) represented in Bolus’ 
figures and in that here given. JD. sagittalis is a native of 
both the South Western and South Eastern regions of 
South Africa, extending in the East to Natal. The 
specimen represented was sent to the Royal Gardens by 
H. J. Elwes, Hsq., F.L.S., from his gardens at Coles- 
borne, Andoversford, which have contributed so many 
rarities to this work, and amongst them more terrestrial 
Cape Orchids than has any other contributor. It flowered 
early in May of the present year.
