Distribution
Brazil: Rio de Janeiro.
Ecology
Epiphytic on trees in rain forest at higher altitudes. Alt. c. 1800 m.
Morphology General Habit
Plant 15 - 35 mm tall
Morphology Leaves
Leaves up to 4 - 12 x 0.5 - 0.9 mm, erect, linear subulate, semi-terete to oval in cross-section, slightly sheathing and obscurely decurrent at base, apex acute
Morphology Reproductive morphology Flowers
Flowers resupinate, not opening widely, diaphanous and snow-white
Morphology Reproductive morphology Flowers Calyx
Dorsal sepal 4.7 - 5 x 0.5 - 1.2 mm, narrowly lanceolate to narrowly ovate lanceolate, acute, abaxially weakly carinate Lateral sepals 5 - 6 x 0.8 - 1.2 mm, obliquely narrowly lanceolate or obliquely linear-ovate, falcate, acute, abaxially slightly carinate
Morphology Reproductive morphology Flowers Column
Column 1.5 mm long (excluding the tabula infrastigmatica), geniculate near the base, distinctly sigmoid at apex, sulcate underneath; stigmatic cavity somewhat elliptic, placed at the base of the column; rostellum 3-lobed, the lateral lobes much shorter than the middle one; tabula infrastigmatica c. 1.5 mm long, bearing a central, longitudinal, conspicuous callus which is somewhat nose-shaped in side view, elliptic or narrowly ligulate and slightly concave from above, flanked by a pair of sub-erect and spathulate arm-like appendages at base; anther c. 1.5 mm long, hooded, clavate, distinctly beaked and somewhat recurved towards the apex, acute; pollinia arranged into two superposed, usually slightly unequal pairs, clavate; stipe c. 1 mm long, slightly spathulate and convex, the base somewhat curved, the apex obtuse; viscidium small, elliptic, slightly concave
Morphology Reproductive morphology Flowers Corolla
Lip 5.5 - 6.5 x 3 - 3.5 mm, rhombic, cuneate towards base, distinctly acuminate at apex; margins slightly erose at middle of the lip, becoming entire towards the base and the apex; base provided with a concave, broadly ligulate callus which is glandular within and somewhat recurved towards the apex; just beyond the main callus of the lip there is an obscure hump or hint of a second callus Petal 4.5 - 5 x 1 - 1.4 mm, narrowly lanceolate, acute, abaxially slightly carinate
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary c. 0.6 mm long, angular in cross-section
Morphology Reproductive morphology Flowers Pedicel
Pedicel c. 3 mm long, somewhat twisted, slightly angular, inconspicuously papillose on the angles
Morphology Reproductive morphology Inflorescences
Inflorescence up to c. 30 mm long, up to c. 6-flowered, racemose; peduncle c. 10 mm long, angular in cross section, covered by few fleshy, falcate, slightly concave, triangular, subulate sterile bracts, up to c. 2.5 x 0.5 mm, acute; rachis c. 10 mm long, slightly flexuous, angular in cross-section; floral bracts similar to the sterile ones, decreasing slightly in size towards the apex of inflorescence
Morphology Roots
Roots several, elongate, terete, thickish, glabrous, flexuous
Morphology Stem
Stem up to c. 3 mm long
Note
This species is closely related to Phymatidium mellobarretoi from which it may be distinguished by the shape of the lip, which has a cuneate base and lacks a lamella projecting beyond the main callus, and by the shape of the rostellum, which has two small, tooth like lateral lobes and a conspicuous middle one. The flowers of P. limae do not open widely in the type collection whereas in P. mellobarretoi the floral segments are always somewhat spread, the lateral sepals being strongly reflexed and the lip deflexed. Phymatidium limae is apparently a rare species and is known only from the type collection. The description provided here is based on the type material and original description. Some characters stated in the type description have been omitted because I have been unable to observe them. Named after Mr. J. Santos Lima who, together with Dr. A. C. Brade, collected the type specimen.
Type
