Ind. Lagenocarpus weigelti (Spreng.) Uittien, PI. Suriname 1(1) : 501. 1943. This species has generally passed under the name of Lagenocarpus uliginosus or Lagenocarpus kunthii. According to Uittien (1943), the correct name for it is Lagenocarpus weigelti (Sprengel, 1826, sub Fuirena) Uittien, because of priority. However, there is still an earlier name, Fuirena verticillata Sprengel (1819). It was validly published and represents this species, thus it takes priority over Fuirena- weigelti, i.e., Lagenocarpus weigelti. A few specialists including Kunth (1837) and H . Pfeiffer (1922) by published record indicate that Fuirena verticillata is not identical with Lagenocarpus kunthii but is the same as L. rigidus. There are apparently two different specimens bearing Sprengel's name, Fuirena verticillata, one in Halle and the other in Berlin. Arguments made by German cyperologists, who may have seen both specimens concerned, indicate the specimen in Halle to represent the present taxon, whereas the specimen in Berlin to be L. rigidus. Dr. Schultze-Motel (Berlin-Dahlem) and Dr. Werner (Halle) were kind enough to investigate the Sprengel herbaria and have found both specimens at present not extant. But, as early as 1842, the specimen at Halle, which is most likely to be the one cited by Sprengel in his Novi Proventes, had been chosen as the type specimen of Fuirena verticillata by Nees, who cited Fuirena verticillata as follows, under Cryptangium. uliginosum: Fuirena verticillata Spr. Nov. Prov. 46. Schult. Mant. II. 136 et Herb, (exempt, originale.) In the same paper, Nees again cited Sprengel's binomial under Lagenocarpus rigidus as '^Fuirena verticillata Spr. Nov. Prov. 46. in Herb. Reg. Berol. nee nov. Prov." These statements are certaintly pertinent to Article 8 of the International Rules of Botanical Nomenclature, and the specimen at Halle should be designated as the type of F. verticillata. Bockeler (1874) also confirms the identity between F. verticillata and Cryptangium uliginosum (= L. kunthii) by citing the former as a synonym of the latter as "—Fuirena verticillata C. Spreng. herb." Furthermore, Sprengel's original description in his Novi Proventus is applicable to Lagenocarpus kunthii (= L. uliginosus), viz. " F. cymis pedunculatis verticillatis, . . . Culmus . . . superne e vaginis verticillatim pedunculos cymosos capillares promens. . . . Pedunculi unciales . . . Squamae exteriores ternae,. . . interiores hyalinae, setis numerosis caducis mixtae.'' For these reasons, Fuirena verticillata is here brought under Lagenocarpus. Finally, the name, Cryptangium uliginosum, is superfluous and illegitimate smce an earlier valid name, F. verticillata, was cited under it as a synonym when published.
