Dendroviguiera is a genus of flowering plants in the sunflower family. [2] Its native range stretches from Mexico into Central America. Formerly part of the Viguiera genus, until a DNA study in 2011 separated out all the shrub/tree species of the Viguiera genus.

Description

Dendroviguiera species generally are shrubs and trees with phyllaries (modified leaves) with oblong, indurated (hardened) bases and short, triangular herbaceous apices (leaf-tips). The pappus (flowerhead) has awns (hair r bristle-like appendages) which are usually broad, greater than 3 mm (0.1 in) mm across. The abaxial (underneath) leaf surfaces usually not densely pubescent (downy; covered with short, soft hairs). [3]

Taxonomy

Originally the (woody) species of Viguiera were placed in Viguiera ser. MaculataeS.F.Blake, Contr. Gray Herb. 54: 62. (1918) in 1918. [4]

Molecular phylogenetic studies by Schilling in 1991, suggested that there is an unexpectedly close relationship between Iostephane (genus of Mexican flowering plants in the family Asteraceae) and Dendroviguiera (formerly Viguiera sect. Maculatae). [5]

Botanists Edward E. Schilling and José Luis Panero in 2002 and 2011, studied the subtribe Helianthinae based on molecular sequences of nuclear ITS, ETS, and cpDNA, coming to a conclusion that that the genus Viguiera Kunth, did not constitute a monophyletic group. Among their conclusions they proposed to reclassify the genus, dividing and relocating its species in at least eleven genera: Aldama La Llave, Bahiopsis Kellogg, Calanticaria (B.L. Rob. & Greenm.) E.E. Schill. & Panero, Davilanthus E.E. Schill. & Panero, DendroviguieraE.E. Schill. & Panero, Gonzalezia , Heliomeris Nutt., Heiseria E.E. Schill. & Panero, Hymenostephium Benth., Sidneya E.E. Schill. & Panero, and ViguieraKunth. [6] [3]

Genus Dendroviguiera was first described and published in Bot. J. Linn. Soc. vol.167 on page 325 in 2011 by . [2] After using plastid DNA sequence data for internal transcribed spacer (ITS) and partial external transcribed spacer (ETS) studies,

The genus name of Dendroviguiera is in honour of Louis Guillaume Alexandre Viguier (1790–1867), who was a French doctor and botanist, [7] preceded by the Greek words dendron meaning 'tree'. [8]

GRIN (United States Department of Agriculture and the Agricultural Research Service) only class it as a possible synonym of Viguiera Kunth and list no species. [9]

Species

As accepted by Kew, [2] and WFO; [10]

Distribution

Most of the species in the genus are found in Mexico, [3] [2] [11] Only one species, Dendroviguiera sylvatica is only found in Costa Rica and Panama. [3]

Habitat

They are normally found in tropical deciduous forests. [3]

Like Dendroviguiera splendens which is found within temperate forests, oak forests and subtropical dry shrublands and at altitudes of 1,600–2,300 m (5,200–7,500 ft) above sea level. [12]

Endangered

Found in Morelos, State of Mexico, Dendroviguiera mirandae on IUCN RED list as "least concern". [11]

While Dendroviguiera splendens (Vara blanca) has been assessed for the IUCN Red List of Threatened Species in 2021 and was listed as vulnerable , due to threats from livestock farming & ranching and logging & wood harvesting, damaging the local habitats. [12] While Dendroviguiera puruana, Dendroviguiera quinqueradiata and Dendroviguiera sphaerocephala have all been assessed as near threatened (NT) for similar reasons. [13]

Uses

Secondary metabolites (or organic compounds) such as germacrolides (GERM), heliangolides (HELI) and furanoheliangolides (FUHE) and tetracyclic diterpenes (TETD) have been characterized from various Dendroviguiera species. [14]

Sesquiterpene lactones 52 and 96, were isolated from Dendroviguiera sylvatica have found to inhibited the nitric oxide production and phagocytosis of macrophages (Dupuy et al. 2008). [15] They and millerenolide and thieleanin have also been used on the growth of melanoma tumors in mice (Taylor et al. 2008). [16]
