Glandularia

Glandularia peruviana

The Glandularia are a plant genus in the family of the verbena family ( Verbenaceae ). This genus was separated from the genus Verbena, and contains about 70 to 80 species that are native only to North and South America.

Description

Glandularia species are mostly herbaceous plants, subshrubs to dwarf shrubs, bushes, erect, prostrate, can stolon- or mat -forming grow, some species form more often at the nodes ( more nodes ) roots. The stems are angular. The arranged alternate, sessile leaves are lobed, pinnatisect to pinnate. Stipules absent.

End or axillary either a ähriger inflorescence or two eared inflorescences that are on a forked branch can be formed. There are lanceolate bracts present. The hermaphrodite flowers are zygomorphic and fünfzählig. The five sepals are fused narrow cylindrical. The fünfrippige, just calyx tube ends in four or five narrow elongated calyx teeth. The crown is 1.5 - up to twice as long as the calyx. The five petals are fused salverform. The upper lip consists of two and the lower lip of three petals. It's just a circle with four stamens present. Two carpels are fused, they are divided by a false septum to a four-lobed, vierkammerigen, superior ovaries with one ovule per chamber ( This reflects the related genera Lippia and Lantana differ there is only one carpel available. ). The stylus is at least three times as long as the ovary. The scar consists of two branches of unequal grain with only a Narbenast Narbenpapillen bears. At Verbena and Glandularia the sterile Narbenast forms a conspicuous, the fertile branch often superior tip ( in these two species of the closely related Junellia and Lippia distinguish where the sterile branch is completely reduced). Pollination is mostly by insects ( entomophily ).

The Klaus fruit, a fruit decay is dominated by twice as long as calyx. It is divided into four large, elongated Klausen ( nutlets ). The Verwachsungsstelle the Klausen at Verbena and Junellia is narrow, in contrast Glandularia wide.

System

After Botta et al. In 1995, the species of the genera Glandularia and Junellia of the genus Verbena be outsourced. One can distinguish these three genera especially at the basic chromosome number: Verbena n = 7, Glandularia n = 5, n = 10 Junellia

In the genus Glandularia there are approximately 70 to 80 types:

• Glandularia alejandrana B.L.Turner
• Glandularia amoena ( Paxton ) Umber ( syn. Verbena amoena Paxton )
• Glandularia araucana ( Phil.) Botta ( syn. Verbena araucana Phil.)
• Glandularia aristigera ( S.Moore ) Tronc. ( Syn: Glandularia tenuisecta ( Briq. ) Small, Verbena aristigera S.Moore, Verbena tenuisecta Briq. )
• Glandularia aurantiaca ( Speg. ) Botta: Glandularia aurantiaca var aurantiaca ( syn.. Verbena aurantiaca Speg )
• Glandularia aurantiaca var glaberrima ( Moldenke ) Botta ( syn. Verbena aurantiaca var glaberrima Moldenke )

• Glandularia bipinnatifida var bipinnatifida ( syn. Verbena ambrosiifolia Rydb ex Small, Verbena bipinnatifida Nutt.. )
• Glandularia bipinnatifida ciliata var ( Benth. ) BLTurner ( Syn: Glandularia bipinnatifida var brevispicata Umber, Glandularia wrightii ( A. Gray ) Umber, Verbena ciliata Benth, Verbena wrightii A. Gray. )
• Glandularia bipinnatifida var latilobata ( LMPerry ) BLTurner ( Syn: Glandularia chiricahensis Umber, Verbena bipinnatifida var latilobata LMPerry )

• Glandularia pulchella var clavellata Tronc.
• Glandularia pulchella var gracilior Tronc.
• Glandularia pulchella pulchella var ( syn. Verbena pulchella Sweet, Verbena tenuisecta auct. )
