[lep-toss-er-ass]
From leptos, slender, and ceros, a horn.
Glabrous plants. Leaf short, broad and smooth. Sepals acute or rather obtuse, the upper one erect or incurved, concave, petals erect, linear-clavate (club-shaped), longer than the sepals. Note by Dr. Rogers: "The one species in this genus is closely allied to Caladenia Menziesii and the genu Eriochilus) which have been included under Leptoceras by some botanists. On the other hand the single member of the genus is commonly placed under Caladenia by taxonomist and is so included by Bentham."

L. fimbriatum, Lindley; fringed. (Caladenia fimbriata, Reichenbach, Eriochilus fimbriatus, F. von Mueller.)
"Hare orchid" "Fly orchid"
Stems 6in. to 1 ft. high. Leaf (occasionally two) clasping stem close to ground, about 1 in. long, ovate lanecolate or oblong. Flowers usually two or three, purple and green. Petals erect, longer than the sepals, clavate. Lip very broad, lobed, fringed at the end, the disk without calli.
W.A.: Greemount, Highbury, Kalamunda, Midland Junction, South Perth, York. May - August.
South Australia, Victoria.
Note by Fitzgerald: "Leaves much more frequently observed than flowers. It is with great reluctance I depart from the naming in 'Flora Australiensis,' but I cannot concur with the inclusion of this with Caladenia, and have placed it in Lindley's Leptoceras for the following reasons: Leaf or leaves not those of Caladenia. In Caladenia I have never seen more than one leaf, always thin and usually hairy; in this plant leaf thick, hard and shining, occasionally two. In Caladenia tubers are generally numerous, in L. fimbriata I have only observed one. The labellum, is without the characteristic glands and is not of the form obtaining in Caladenia, the stigma is very different in form being triangular and deep sunk, the upper parts overhanging, not oval and shallow; and the flowers have the peculiarity of drying and continuing in a state hardly to be distinguished from the fresh flowers long after the seed has been shed. It approaches C. Menziesii only (so far as I can see) in having erect linear-clavate petals, in which C Menziesii is itself peculiar, L. fimbriata seems to come nearer to Eriochilus than to Caladenia but differs from it again."
