(Platyloma) sagittata — Plat-yl-o'-ma j sag-it-ta'-ta (arrow-shaped), Moore and Houlston. This greenhouse species, of erect habit and of a somewhat deciduous nature, is the Pteris sagittata of Cavanilles, and the Allosorus sagittatus of Presl. It is a native of Mexico, and is closely allied to P. cordata, and nearer still to the variety fiexuosa, but its fronds are not zigzag, and the habit, instead of being drooping, is upright. Lowe states that P. sagittata was raised from spores at the Royal Gardens, "Kew, in the year 1842. Its fronds, triangular and bipinnate (twice divided to the midrib), are pro- duced from a short-creeping rhizome, and borne on pale brown or straw-coloured stalks Sin. to 12in. long. They- are l£ft. to 2ft. long, and their Fig. 25. Portion of Fertile Frond of stalked pinnules (leafits), smooth and of a glaucous Pelfsea sagittata r ' ° (nat ) (bluish-green) colour and soft, papery texture, have the singular property of rolling their margins under, and thus becoming quite arrow-shaped when fertile (Fig. 25) ; in the barren state these leaflets are heart-shaped.—Lowe, Ferns British and Exotic, hi., t. 28.

It is very like P. auriculata in habit and general appearance, differing from that species principally in its finer venation and narrower involucre.—Hooker, Species Filicum, ii., p. 141, t. 117b. P.
