Species Utricularia praetermissa P. Taylor
Note TYPE: Costa Rica, Prov. San Jose, La Palma, 1550 m, Aug. 1898 Tonduz 12471 (K, holotype; BM, F, G, M, MO, US, W, isotypes ).
Description Perennial epiphytic herbs; stolons branched, filiform, radiating from the base of the inflorescence, several swollen at or near the point of origin to form ellip- soid tubers 1-2 cm long. Photosynthetic organs 2-4 from the inflorescence base, leaflike, 8-15 cm long; lamina coriaceous, multinerved, the nerves drying promi- nent on both surfaces, narrowly elliptic, the apex acute or acuminate; pseudo- petiole usually as long as or longer than the lamina. Traps borne on filiform stolon-branches, ovoid, stalked, ca. 1 mm long, the mouth basal, the upper lip with 2 subulate recurved appendages. Inflorescences to 30 cm long; peduncle 1.5-2 mm thick, 1-3-flowered; bracts linear-lanceolate, acute or acuminate, straight, 5-7 mm long, the bracteoles similar but narrower and sometimes shorter, the sterile scales on the peduncle usually ca. 4, similar to the bracts but usually smaller; pedicels erect, 2-4 times as long as bract. Flowers with the calyx lobes Utricularia praetermissa P. Taylor, sp. nov. Species affinis U. unifolia Ruiz & Pavon sed bracteis multo brevioribus et corolla calcari longiore apice deflexo satis differt. subequal, ovate, ? obtusely acuminate, 2.5-3 cm long, 1.2-1.5 cm wide; corolla white or mauve with a yellow palate, 4-5 cm long, glabrous or with a few stipitate glands, the upper lip broadly ovate to orbicular, a little shorter and wider than the upper calyx lobe, the lower lip much larger, transversely elliptic or almost orbicular, to 5 cm wide, apically retuse, the palate gibbous, prominent, the spur narrowly cylindrical, about as long as lower lip, curved upwards, abruptly terminating in an acute subulate deflexed apex. Capsules + globose, ca. 1 cm long; seeds numerous, narrowly cylindrical-fusiform, ca. 0.8 mm long.
Habit herbs
Distribution This species occurs in Costa Rica, Nicaragua, Panama, and probably Colombia.
Note The identification of Utricularia praetermissa, which is closely allied to U. unifolia and U. alpina, is not difficult with reasonably complete material. From U. unifolia it differs in its much shorter straight bracts and bracteoles, its deflexed spur apex, and its relatively short pseudopetiole. From U. alpina it may be dis- tinguished by spur apex, the shape of the lower lip, and the shape and venation of the photosynthetic organs. Within this group of large-flowered epiphytic Utricularia species there is one other (to be described shortly) which apparently occurs only in a restricted area in northern Venezuela. Its corolla is similar in shape to that of U. praetermissa but is smaller. This is a much smaller plant with very small photosynthetic organs, only a centimeter or two long.
