79. ELISENA longipetala.

E. longipetala perianthii laciniis acuminatissimis convolutis. Folia numerosa, ferè bipedalia, sesquiunciam lata, lætè viridia, subacuta, leviter carinata, margine lævia, subtus glaucescentia. Scapus 2-3-pedalis, ancipiti- convexus, solidus, cœruleo-viridis, vix glaucescens. Umbella 5-flora, spathâ polyphyllâ scariosâ reflexâ; pedicelli rigidi, semunciam longi, trigoni. Ovarium trigonum, ovatum, levitèr glaucescens, triloculare; loculis apice inanibus, basi dispermis ; ovulis erectis obovatis, carnosis. Perianthium tubo brevi (semunciali) herbaceo, rigido, trigono, cum ovario continuo sed demum marcescente ; lacinis 4 uncias longis, linearibus, acuminatissimis, pone basin dorso herbaceis, cæterum albis, 2 inferioribus cæteris paulo magis declinatis, amnibus demum reflexis et convolutis. Corona alba, membranacea, cylindracea, sesquiuncialis, declinata, apice paulo dilatata,

margine 6-fido, revoluto: laciniis irregulariter tridentatis, dente intermedio, productiore. Stamina 6, declinata, subæqualia; filamentis subulatis, gla- berrimis, perianthio subæqualibus ; antheris linearibus, irregulariter cohæren- tibus. Stylus filiformis, declinatus, glaber; stigmate simplici, haud dila- tato, vix papilloso. To the cultivators of bulbous plants this fine species will form a welcome addition. It is very nearly related to the Pancratium ringens of the Flora Peruviana, out of which Mr. Herbert has formed his genus Elisena, and like it is a native of Peru. It was obtained from Lima by Richard Harrison, Esq. of Aighburgh, near Liverpool, and it blossomed in the stove of that gentleman in May 1838. The leaves are much like those of an Amancaes; the flowers are of a delicate semi-transparent white, and are remarkable for their long weak sepals, which are rolled up, and in that state scarcely wider than the long white declinate stamens. The technical description given above will enable the Botanist to see how very distinct this genus is from Pancratium.
