EUCHARIS grandiflora; foliis in stirpe florifera 2-4 cordato-ovatis medio canali- culatis, scapo 3-5-floro, perigonii laciniis exterioribus ovatis interioribus latioribus, ovarii loculis 16-18-spermis. EUCHARIS grandiflora. Planch. et Lind. Flore des Serres, v. 9. p. 255. t. 957.

From the collection of Messrs. Veitch and Son, King's Road, Chelsea, where it bears the appellation of Eucharis Amazonica, a name we find nowhere recorded, and there can be no question of its being the E. grandiflora of Planch. and Linden, in the work above quoted, where however we find the specific character at variance with the figure, "perigonii laciniis exterioribus ovato- lanceolatis interiora latitudine excedentibus :" the reverse is the case, both in their figure and in our specimens. Those authors notice its affinity with their E. candida of the same work, vol. ix. MARCH 1ST, 1857.

p. 107, a species with which we are not acquainted. With us it blossoms in the stove in the winter months, and the truly noble pure white flowers, the large staminal cup slightly suffused with pale yellow-green, are highly fragrant. Inhabits the Province of Choco, New Granada. It is impossible not to see a very close analogy between Linden and Planchon's genus Eucharis and Eurycles of Salisbury (in our Tab. 3399); the true nature of the bulbs, leaves, and flowers are the same. The latter genus is exclusively a native of the warm parts of the Old World, whilst our plant is peculiar to the New. DESCR. Leaves rising from a rather large tunicated bulb. Petioles from five to seven inches long, semiterete, plane or slightly grooved above: the blade about equal in length to the petiole, or longer, ovate, shortly acuminate, striated, dark green above, paler beneath. Scape a foot or more high, bearing about six or seven large white fragrant flowers, which emerge from a bifid membranaceous spatha. Peduncles very short, with subu- late bracteas at their base. Perianth hypocrateriform : the tube curved, narrow for its greater length, expanding upwards, three inches long, including the oblong, green, subtrigonal ovary. Limb of six, horizontal, acute or subapiculate segments: three outer exactly ovate; three inner cordiform-ovate. Staminiferous cup large, white, tinged with green, six-lobed at the margin, each lobe bifid, with its obtuse lobules subdivergent, and bearing a stamen in the centre. Filament short, subulate, erect: anther linear, versatile. Ovary oval, trigonous, three-celled, with fourteen to sixteen ovules, in two rows. Style longer than the stamen: stigma three-lobed.
