    Cryptangium stellatum Bockeler, Linnaea 38: 421. 1874. Acrocarpus stellatus Nees ex Bocklr., Linnaea 38: 422. 1874. Nomen invalidum ex synonymis. Lagenocarpus stellatus (Bockeler) O. Kuntze, Eev. Gen. PL 2: 754. 1891. Bidymiandrum guaiquinimae Schnee, Bol. Soc. Venez. Cienc. Nat. 9: 81. 1944. Syn. nov. Schnee (1944) recognized three species in this genus, when he proposed Didymiandrum guaiquinimae. D. fiexifolium is in this paper transferred to Everardia. Schnee's reason for establishing D. guaiquinimae is obscure as he merely stated as "comprende 3 especies que son endemicas en las montanas altas de la Guayana Venezolana. ..." Examining an isotype of D. guaiquinimae we come to the conclusion that it is identical with D. stellatum, which is the sole species of the genus.

  • Distribution

    Distribution. This species is rather common in the east half of the Roraima Sediment area from Cerro Sipapo eastwards to Pakaraima Mountains in British Guiana, thus the range resembles that of Everardia montana subsp. monfana and Cephalocarpus rigidus. The following specimens have been examined iacluding the type of synonymized names. VENEZUELA. Amazonas: Cerro Sipapo, Maguire & Politi 27830 [male], 27875 [male], 27951 [male] & [female]; Cerro Huachamacari, Maguire, Cowan & Wurdack 30093 [male];
