The plant genus of the sun rose ( Helianthemum ) belongs to the cistus family (Cistaceae). The 95 to 175 species, depending on the author, are mainly found in the Mediterranean region.
Origin of the common name
The common German name Sonnenröschen comes from the ability of the flowers to align themselves with the sun. The bright yellow flowers and the preference for sunny places may also have contributed to this.
description
Vegetative characteristics
Helianthemum species are mostly evergreen to semi - evergreen subshrubs to shrubs , rarely perennial or annual herbaceous plants .
The leaves are usually opposite, or the topmost alternate. The leaf blades are simple. There are often Stipules present, sometimes they are missing.
Generative characteristics
The flowers are solitary and few to many in terminal zymose , racemose , umbrella-racemose , capitate , or rarely panicle inflorescences together. The flowers are mostly stalked, rarely sessile.
The hermaphrodite flowers are radially symmetrical and five-fold. Of the five sepals, the outer two are linear and about half the size of the inner three, which are unequal and relatively wide. The petals can be shorter to much longer than the sepals. The five free petals are most often yellow to orange-yellow, there are also types in the colors purple, pink, red, scarlet and white. There are usually many stamens , all of which are fertile. The ovary is on top. The slim stylus ends in a relatively large, capitate stigma .
The capsule fruits, which are simple or incompletely divided into three fruit compartments, are triangular and contain many seeds.
Systematics and botanical history
Taxonomy
The genus Helianthemum was abridged by Philip Miller in The Gardeners Dictionary ... in 1754 . , 4th edition, Volume 2. The botanical genus name Helianthemum is derived from the Greek words helios for "sun" and anthemos for flower . Helianthemum nummularium Mill. Was specified as the lectotype species by Alfred Rehder in Notes on some cultivated trees and shrubs , page 471 in 1949 . Synonyms for Helianthemum Mill. Are Anthelis subg. Horanthes Raf. , Crocanthemum Spach , Halimium sect. Lecheoides (Dunal) Grosser , Halimium sect. Spartioides Grosser , Helianthemum sect. Lecheoides Dunal , Helianthemum subg. Lecheoides (Dunal) Reiche , Heteromeris Spach , Horanthes Raf. , Rhodax Spach , Taeniostema Spach .
Internal system
Helianthemum is the most biodiverse, most widespread and taxonomically most complex genus of the Cistaceae family. For a comprehensive study of all the data were Helianthemum studied species, sequences of the plastid - DNA (ndhF, psbA trnH, trnL-trnF) and the nucleus - ITS region gathered and the results by Aparicio et al. Published in 2017.
Classification of the genus Helianthemum before 2017
By 2017, the 95 Helianthemum species and subspecies will be divided into two sub-genera with ten sections:
- Subgenus Helianthemum Mill .: It contains six sections:
- Section Argyrolepis Spach : The only species occurs on the Iberian Peninsula and in northern Algeria.
- Section Brachypetalum Dunal : The approximately five species occur in Macaronesia and the Mediterranean region.
- Section Eriocarpum Dunal : The approximately 24 species occur in Macaronesia and Saharo-Arab and Irano-Turanian regions (perhaps also the Mediterranean region).
- Section Helianthemum : The approximately 43 species (with 21 subspecies) occur in Macaronesia, in the Mediterranean area and in the Eurosiberian area.
- Section Lavandulaceum G.López : There are about two species in the Mediterranean area.
- Section Pseudomacularia Grosser : The four or so species occur in the Irano-Turanian region.
- Subgenus Plectolobum Willk. : It contains four sections:
- Section Atlanthemum (Raynaud) G.López & al. : The only species occurs in the Mediterranean area.
- Section Caput-felis G.López : The only species occurs in the Tyrrhenian area.
- Section Macularia Dunal : The roughly two species only occur in the Maritime Alps.
- Section Pseudocistus Dunal : The approximately 17 species (with 23 subspecies) occur in the Mediterranean and Eurosiberian areas.
In Aparicio et al. In 2017, there are three clades that do not confirm the previous division into the previous sub-genera and sections; it is proposed that the monophyletic genus Helianthemum should also be reorganized in the previous scope .
