In 1892 the late Dr. M. T. Masters gave a description in the Gardeners' Chronicle of an interesting hybrid which had been raised by Messrs. Clibran. The parents of this hybrid were Urceolina pendula, Herb., figured at t.5464, and Eucharis grandiflora, Planch., figured at t.4971 of this work; the name given to the plant was Urceocharis Clibrani. Two years ago the plant now figured was acquired for the Kew Collection by purchase from Messrs. Sander & Sons, St. Albans. This plant had been for- warded from Peru by the firm's collector, Mr. Forget, who, it is understood, had met with it in a wild state and in a remote part of that country. It flowered in a moist tropical house at Kew in July, 1909 ; another specimen, identical in every respect, flowered at St. Albans in Januarv, 1910. So nearly allied to Urceocharis Clibrami, Mast., is this Peruvian form, which Mr. Wright has described as Urceocharis edentata, that there is hardly room for doubt as to its being another hybrid, perhaps identical as to parentage with Messrs. Clibran's plant, but FEBRUARY, 1911.

in this case probably a natural one. The two plants referred to Urceocharis have a perianth with a narrowly cylindric tube and a camnpanulate limb, the lobes of which curve outwards at the apex only ae as in Urceolina, and not, as in Eucharis, almost at right angles to the tube. They further agree with Urceolina in being deciduous. Tle flowers of Urceolina, are either devoid of a staminal corona or possess one that is quite rudimentary : those of Eucharis, have a distinct corona with free teeth between the bases of the filaments. In the hybrid raised by Messrs. Clibran there are two such teeth about one-third the length of the filaments between each pair of stamens. But in the pre- sumably wild plant sent by Forget from Peru, which in every other respect is indistinguishable from Urceocharis Clibrani, there is no trace of these appendages.
