Anatomical and nutlet differentiation between Teucrium montanum and T. polium from Turkey
TLDR
Comparative anatomical and micromorphological studies of the two Teucrium montanum and T. polium species show that both taxa are similar in stem anatomy and their leaves exhibit xeromorphy, however, trichome morphology on the stems and the leaves appear to have a taxonomic value in segregation of the pair.Abstract:
Teucrium montanum L. and T. polium L. are the two closest Teucrium L. species from sect. Polium (Mill.) Schreb in Turkey. In addition, they are sympatric for some part of their range in Turkey. In this study, comparative anatomical and micromorphological studies of the two species are carried out. They have been investigated by their leaf and stem anatomical features, as well as nutlet micromorphological characteristics. The results of anatomical studies show that the anatomical characters of both taxa are observed to be similar to the general features of the family Lamiaceae anatomy, except for lacking rich collenchyma at the corners. Both taxa are similar in stem anatomy and their leaves exhibit xeromorphy. However, trichome morphology on the stems and the leaves appear to have a taxonomic value in segregation of the two taxa. Light and scanning electron microscope studies on the nutlets also show that nutlet shapes, measures and surface micromorphologies are different in the two species. Whereas nutlet surfaces are bireticulate in both species, the nutlets are larger and primary sculpturing is more distinct in T. polium than in T. montanum. Moreover, the nutlets are oblong to oblong-ovoid and larger in T. polium, but ovoid and smaller in T. montanum.read more

TL;DR: It was revealed that the isolated population of T. montbretii represent a new subspecies of Isotriodon, and trichome types on the vegetative organs and nutlet shape and sculpturing are generally the same or similar in the studied taxa, but trichomes on the nutlets are different among them.

Micromorphological characters on nutlet and leaf indumentum of Teucrium sect. Teucrium (Lamiaceae) in Turkey
TL;DR: The indumentum types on nutlets and leaves have a high taxonomical value for the species of the genus Teucrium and the current study supports this grouping.

I. morphological nutlet characteristics of some lamiaceae taxa in saudi arabia and their taxonomic significance
TL;DR: Observations revealed that nutlet color, shape, size, presence of areole are of limited taxonomic value, however the pericarp sculpturing are the most important diagnostic characters for differentiating the species through a constructed key.
