Type :—Brasilia meridionalis, F. Sellow s.n . Lectotype (designated here): K 00584552!; isolectotypes G 00098413!, P 00130102!. The material examined by Kunth at B which photograph we examined at F is no longer extant. The above specimens at G, K and P has the same label as the B sheet, with the same handwriting on it which is not from Kunth, and were probably not examined by him. Most of the remaining types at B examined by Kunth (e.g. Sellow 249 ) or the Berlin types at F (e.g. Sellow s.n .— Scleria junciforme ) have notes from him which handwriting is different from the mentioned labels. The material selected as lectotype is a well preserved and complete plant while the materials at P and specially at G are incomplete or fragmented. Lagenocarpus tenuifolius (Boeck.) C. B. Clarke (1908: 64) . ≡ Cryptangium tenuifolium Boeckeler (1888: 32) . Type :— Rio de janeiro , Glaziou 15595 , 15596 . Lectotype (designated here):— BRAZIL : environs de Rio de Janeiro et D’Ouro Preto, 1883–1884, A.F.M. Glaziou 15595 (K 000584538!; isolectotypes BR 511243 !, F no. 538823!, G 00098410!, P 000130105!, 000272646!, 272647!) Boeckeler (1888) described Cryptangium tenuifolium based on two syntypes . We have examined nine specimens and selected Glaziou 15595 at K as the lectotype because it has more individuals, two complete inflorescences, and fruits in an envelope. It is worth to note that at K database Glaziou 15596 is erroneously registered as 15696 .
