oy. ome time ago Anguloa uniflora var. Treyerani was figured in this 
= ¥ work (vol. II, p. 47, t. 310), and now a second variety is given. The 
ES. former one was characterised by the possession of an unusual number 
of spots near the base of the lip; but in the present one not only are these 
absent, but also the minute pink spots which are often found on the sepals 
and petals, thus leaving the flower of a uniform ivory-white, in allusion to 
which the name was given. It possesses no other distinguishing character. It 
was described from the collection of Sir Trevor Lawrence, of Burford Lodge, 
Dorking. 
The species is rather widely diffused, being found from Southern Peru to 
the north of New Granada, and probably into Venezuela, yet it seems subject 
to very little variation, and that chiefly in colour. For nearly half-a-century 
nothing was known of it beyond the original description, when suddenly in 1844 
it flowered among the collections sent home by M. Linpen, together with 
A. Clowesii and A. Ruckeri, since which time no new species has appeared. 
Two or three forms which have been described as such have proved to be 
only varieties of the older species. Besides these, two natural hybrids have 
since appeared, one of which as again been lost sight of. The other, 
Anguloa % media Reus. F., is one of the few hybrids which has both originated 
in a wild state, and been raised artificially under cultivation.
