Biseriate glandular trichomes and uniseriate flagellar covering hairs occur in all or most of the 20 genera examined and thus do not provide important taxonomical hints. In contrast, T- or Y-shaped hairs have been found inSantolina, Anthemis, Leucanthemopsis, Dendranthema, Tanacetum,Balsamita, Sphaeromeria (?),Artemisia, andAchillea clavenae only. Stellate hairs appear to be rare (inSantolina andArtemisia sect.Dracunculus). For details, additional hair types, and relationships see Tab.1 and Fig… 

Glandular hairs of the ovary: a helpful character for Asteroideae (Asteraceae) taxonomy?

The usefulness of glandular hairs of the ovary for taxonomic purposes is discussed and hair morphology and distribution, cell number, and presence of subcuticular chambers and chloroplasts are considered.

Glandular trichomes of Tussilago Farfara (Senecioneae, Asteraceae)

The study has shown that the practical value of the aerial organs of coltsfoot is provided with flavonoids produced in the capitate glandular trichomes, similar to the metabolites from leaves, in which photosynthesis happens.

Trichomes in the tribe Lactuceae (Asteraceae) — taxonomic implications

This subtribe is characterized by a unique combination of two trichome types and comprises the following genera: Andryala, Hieracium, Hispidella, Pilosella, Stenotheca, and a new circumscription of the Hieraciinae is proposed, in accordance with recent molecular data.

Micromorphological and Anatomical Characteristics of the Genus Chrysophthalmum Schultz Bip. (Asteraceae) Growing in Turkey

A diagnostic key based on combined leaf, trichome and cypsela characteristics of the Chrysophthalmum species has been given.



Beiträge zur Systematischen Anatomie derAnthemideae: Die Spaltöffnungsapparate

The subdivision of theAnthemideae into two subtribes purely on the grounds of the presence or absence of receptacular paleae can no longer be maintained. Anatomical data may serve as a basis for a

The classical concept of the Asteroideae tribes has been confirmed in general, but recent investigations suggest numerous corrections, and some genera (e.g.Liabum, Echinops, Tarchonanthus, Arnica) do not fit into the scheme.

Zytotaxonomische Untersuchungen des Formenkreises Achillea millefolium (Asteraceae) in der DDR

Chromosomenzahl, Morphologie and Proazulengehalt of 70 Wildpopulationen and deren Kulturen wurden untersucht, indicating clearly the occurence of the following species: A. millefolium-complex and among other species of the sect.

The genus Cotula (Asteraceae) in New Guinea. Sertulum Papuanum 21

This group of small, mat-forming species has been known in New Guinea to date only by C. leptoloba Mattfeld, but the species limits are not well known and the descriptions may need revising when further material is available.
