The fruit and seed micromorphology of 22 species of Geranium, representing the eight sections of the genus represented in Iran (G. sectt. Dissecta, Geranium, and Tuberosa of subgen. Geranium; sectt. Batrachioidea, Divaricata, Lucida, Ruberta and Trilopha of subgen. Robertium), have been examined by scanning electron microscopy (SEM). Macro‐ and micromorphological characters, including fruit and seed shape, size, color, hair type and density, mericarp ornamentations, hilum position, seed coat pattern, epidermal cell shape, and anticlinal and periclinal cell walls, are presented. Two microsculpturing patterns are recognized on the mericarp surface: reticulate and pusticulate. The micromorphology of the seed coat showed four distinctive cell patterns. The seed epidermis is constructed either of polygonal, elongated polygonal, or square to rectangular cells. The polygonal type is the most common among the studied species, but the variation in testa cell characters, their size and shape, may provide further information and useful diagnostic characters at specific and infraspecific rank. The shape and color of the seeds are, however, of little systematic value. Fruit characters were found to be important for separating taxa at infrageneric rank and our results show that the species can be separated into subgenera and sections based on fruit morphology.

“…400 species in temperate areas and tropical mountains throughout most of the world (Aedo, Muñoz Garmendia & Pando, 1998a). A brief history of the generic delimitation and infrageneric classification, as well as a description of the genus, can be found in Aedo (1996). In addition, a key for subgenera and sections can be found in Aedo, Aldasoro & Navarro (1998b) and Aedo et al .…”

“…The subgen. Erodioidea which includes 22 species in four sections has recently been monographed (Aedo, 1996, 2001a): two sections are in the Mediterranean and western Asia, one is centred in the mountains of tropical East Africa, and one is in southern Brazil and northern Argentina. According to Yeo's (1984) sectional classification, the subgen.…”

The sections Andina and Chilensia of Geranium from South America, Australia and New Zealand are taxonomically revised. Fruits with ‘seed ejection‐type’ dispersal have been found in all species, which confirms their classification within subgen. Geranium. Section Andina consist of four species, while sect. Chilensia comprises 11 taxa. In sect. Andina, G. brevicaule and G. parodii, previously considered as synonyms or recognized as infraspecific taxa, are accepted at species level. In contrast, G. tucumanum, G. sessiliflorum ssp. novaezelandiae and 17 other taxa have been reduced to synonyms. In sect. Chilensia, G. patagonicum, G. fiebrigianum and G. drumondii have been considered as synonyms of G. berteroanum, G. fallax and G. solanderi, respectively. Additionally, another 24 taxa have been reduced to synonyms. Diagnostic morphological features are analysed and compared within and between the sections. A multivariate morphometric study from 258 specimens was carried out to test the most significant characters. The chromosome number of six species (five never previously counted) was established. A key, species descriptions, a complete list of synonymy, a list of specimens examined and distribution maps are provided. Most species are illustrated for the first time. Thirty‐seven lectotypes and one neotype are designated. © 2005 The Linnean Society of London, Botanical Journal of the Linnean Society, 2005, 149, 1–68.
