Angiosperm‐wide analysis of fruit and ovary evolution aided by a new nuclear phylogeny supports association of the same ovary type with both dry and fleshy fruits

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 2, Page 228-251, February 2024.
Phylogenetic analysis and molecular dating elucidate relationships for orders and families, trace crown angiosperms’ Triassic origin, unveil parallel carpel fusions in early eudicots, monocots, and magnoliids and associate specific fruit types sharing the same ovary type.

Pollen morphology of Boraginaceae s.l. from Brazilian forest fragments: aperture types and ornamentation on Cordiaceae and Heliotropiaceae

open access: yesPalynology, 2021
Boraginaceae s.l., the single family of Boraginales, are extremely diverse in terms of morphology, and their species are well distributed in South America especially in Brazilian ecosystems. The pollen morphology of 11 Brazilian native species and four genera (Cordia L., Varronia P. Browne, Heliotropium L. and Myriopus Small) of Boraginaceae s.l.

MORFOANATOMÍA FOLIAR COMO EVIDENCIA TAXONÓMICA EN LA DELIMITACIÓN DE LAS ESPECIES QUE FORMAN EL COMPLEJO Varronia bullata (CORDIACEAE) [PDF]

open access: yes, 2020
The neotropical genus Varronia P. Browne is one of the most problematic, taxonomically, among the Boraginales. This may be due to the frequency of overlapping the boundaries between intra and interspecific variation of some characters.
