Summary: Portulaca hirsutissima is a succulent herb that occurs in open fields, sandy or rocky soil in distinct regions in Brazil, belonging to the Portulacaceae family. We analyzed the external morphology, seeds and pollen grains in representatives of this species and related morphotypes along their known distribution. We observed a consistent variation in their micromorphology and two new species are here described and illustrated. Portulaca giuliettiae occurs in Eastern Brazil, from Paraiba to Rio de Janeiro and P. goiasensis is restricted to the Chapada dos Veadeiros, in Central Brazil, while P. hirsutissima is now considered as restricted to Minas Gerais State.

O grupo apresenta taxonomia complexa, com caracteres macromorfol?gicos vari?veis e muitas vezes de dif?cil interpreta??o. Neste trabalho foram analisados caracteres micromorfol?gicos das esp?cies que ocorrem no Brasil, como a ornamenta??o das sementes e morfologia pol?nica, em busca de melhor compreender os limites taxon?micos entre as esp?cies. As varia??es observadas envolveram a presen?a de poros ou colpos distribu?dos em todo gr?o de p?len, permitindo a identifica??o de tr?s tipos pol?nicos: pantossincolpado, com colpos organizados em pent?gonos; pantossincolpado, com colpos organizados em espiral; e pantoporado, com poros isolados e organizados em poliedros. A ornamenta??o das sementes forneceu os caracteres taxon?micos mais importantes e permitiu a separa??o de todas as esp?cies analisadas, apoiando inclusive a recente proposi??o de duas novas esp?cies end?micas do Brasil, relacionadas a P. hirsutissima e tamb?m distintas pela morfologia pol?nica.Submitted by Ricardo Cedraz Duque Moliterno (ricardo.moliterno@uefs.br) on 2016-09-26T21:20:40Z No. of bitstreams: 1 THA?LA VIEIRA ALVES DOS SANTOS_v_final_ficha-2.pdf: 5538347 bytes, checksum: f6306a15edb73efd871da71bcbbdd53c (MD5)Made available in DSpace on 2016-09-26T21:20:40Z (GMT).
