Life history evolution and genome size in subtribe Oncidiinae (Orchidaceae). [PDF]
Annals of Botany, 2005 Within Oncidiinae, there are several groups of species that are effectively annuals, and we wished to see if these species had smaller genome sizes than average for the subtribe.Fifty-four genome size estimates (50 of which are new) for species in subtribe Oncidiinae (Orchidaceae) were examined for the first time in a phylogenetic context to evaluate ...

Capanemia (Oncidiinae): an orchid genus revised and simplified
Plant Systematics and Evolution, 2020A taxonomic revision of Capanemia (Orchidaceae) was completed after morphological, nomenclatural and phylogenetic studies. Our analyses do not support the infrageneric classification (Capanemia sect. Capanemia and Capanemia sect. Planifolia) proposed by Pabst in the seventies and recovered Sanderella as the sister group of Capanemia, albeit with low ...

Seed Morphology in the Oncidiinae and Related Subtribes (Orchidaceae)
Systematic Botany, 1988A survey of seed morphology, using scanning electron microscopy, of the Oncidiinae and related Neotropical subtribes found that the majority of these taxa exhibit a uniform seed condition, designated the Maxillaria type. The two major variants within the Oncidiinae are anticlinal wall ornamentation and two different forms of extensions of the testa ...
