The family is large and diverse, characterized by radially symmetric flowers with a fundamentally saucer-shaped hypanthium and peripheral calyx, corolla, androecium, and, usually, superior gynoecium. Considerable variation occurs in important details of flower and fruit, this enhanced by a very adaptable hypanthium, which is discussed in more detail below.<p><p>Rosaceous inflorescences vary in the number of flowers from one to about 500. A great variation occurs also in inflorescence form, though a pattern is perceived when they are viewed as reduction series from a terminal, determinate panicle that is fundamentally bracteate, thus generating a range of panicles, racemes, corymbs, cymes, solitary flowers, or other forms. In this treatment, appendages on the inflorescence are distinguished by the terms bract and bracteole. Bract is used for the larger, laminate, usually chlorophyllous leaf homologues that subtend axes and may be indistinguishable from foliage leaves. Bracteoles are scalelike, often membranous, often caducous, and of uncertain homology, in part due to not being restricted to axis-subtending positions.<p><p>The floral architecture in Rosaceae is radially symmetric around a disc-shaped to urceolate hypanthium. Flowers normally have a four- or five-merous corolla and calyx; great variation is found in the numbers of stamens and carpels. Pollination is usually entomophilous, the flowers having normally green sepals and showy, often more or less clawed, usually white, yellow, or pink, less commonly red or green, petals. The flowers in some genera are relatively small and anemophilous and may lack one or two of the principal whorls. An unusual feature of some rosaceous flowers is the torus, a pad of receptacular, usually spongy, tissue, sometimes relatively large, in the center of the hypanthium that, when present, bears the gynoecium. Another unusual feature of some genera is an epicalyx that comprises a ring of sepaloid bractlets, usually of the same number as sepals, which is located on the hypanthium proximal to the calyx.<p><p>Fruit types are particularly significant both in rosaceous identification, taxonomy, and diversity, as well as for successful dispersal. Fruit in Rosaceae may be either dry, then dehiscent or not, or succulent and indehiscent; it sometimes involves accessory organs such as the torus or a persistent hypanthium.<p><p>Dry indehiscent fruits are achenaceous, in certain cases involving modifications to the style. In anemochorous (adapted for dispersal by wind) situations, this may involve a plumose style, for example, <i>Cercocarpus</i>; in epizoochorous (distributed on the outside of animals) cases, the styles may bear stiff hairs or barbs, for example, <i>Geum</i>. Alternatively, achenaceous fruits may lack styles (sometimes due to abscission) or, more commonly, have a relatively short one, for example, <i>Potentilla</i>. In situations where there appears to be no significant post-flowering function for the style, dispersal may be myrmecochorous (by ants), anemochorous, or in the rare torus-borne cases (for example, <i>Fragaria</i>), the fruit may be endozoochorous (eaten by animals and passed through the gut). Sometimes, fruits with such styles are aggregated in acheneta that rely on barbed, persistent hypanthia for epizoochorous dispersion, for example, <i>Acaena</i> and <i>Agrimonia</i>. Dry dehiscent fruits are follicular with seeds normally distributed by air after splitting of the ripe follicle, for example, <i>Gillenia</i>.<p><p>Succulent, endozoochorous fruits exhibit a similar range of variation. The most common types are: multiple drupelets on the surface of a more or less conic torus (for example, <i>Rubus</i>); individual and sometimes large drupes on a flat receptacular apex (<i>Prunus</i>); pomes, which are berrylike fruits in which a fleshy hypanthium more or less completely surrounds and is generally more or less fully adnate to the carpels (for example, <i>Amelanchier</i>, <i>Crataegus</i>). The result is that a terminal orifice may remain open, often bearing floral remnants around its rim. Pomes with hard pyrenes are sometimes distinguished as polypyrenous drupes, a term not used in this treatment due to antonymic confusion caused by combining the roots for pyrene (hardened mesocarp) and drupe (fleshy mesocarp), although the relevant distinction is well recognized (J. Rohrer et al. 1991).<p><p>Some important temperate fruits are members of the Rosaceae: apples (<i>Malus</i>), pears (<i>Pyrus</i>), almonds, apricots, cherries, peaches, and plums (<i>Prunus</i>), blackberries and raspberries (<i>Rubus</i>), strawberries (<i>Fragaria</i>), loquat (<i>Eriobotrya</i>); minor fruits include those of <i>Amelanchier</i>, <i>Crataegus</i>, <i>Cydonia</i>, <i>Mespilus</i>, and others. Some genera are popular in ornamental horticulture in North America, for example, most of the above as well as, especially, <i>Chaenomeles</i>, <i>Cotoneaster</i>, <i>Pyracantha</i>, <i>Rhaphiolepis</i> Lindley, <i>Sorbus</i>, <i>Photinia</i>, <i>Physocarpus</i>, <i>Rosa</i>, and <i>Spiraea</i> among trees and shrubs; and <i>Filipendula</i>, <i>Geum</i>, <i>Potentilla</i>, and <i>Spiraea</i> among plants suitable for flower borders.<p><p>Apomixis is a feature of some rosaceous genera and may make taxonomic decisions difficult or equivocal in genera such as <i>Alchemilla</i>, <i>Amelanchier</i>, <i>Crataegus</i>, <i>Rubus</i>, and others. Apomixis always seems to be associated with polyploidy and often with hybridization; in some apomictic genera, sexual species and apomicts are facultatively sexual.<p><p>Rosaceae lack alkaloids and blue anthocyanic pigments. Some have foliage or seed that becomes toxic due to hydrolysis of benzaldehyde cyanohydrins.<p><p>The great diversity of Rosaceae reflects the age of the family (since at least the mid Eocene) and its evolutionary success. The family has needed no fundamental change in circumscription since Jussieu first recognized it, the sometimes included outgroups, for example, Chrysobalanaceae, Neuradaceae, already being confidently excluded in more recent pre-molecular classifications, while segregate families (for example, Malaceae) have received little currency. This reflects a lack both of close neighbors and of large internal discontinuities. Species limits are often debatable, especially where apomixis is present; generic limits are much more fixed, apart from the familiar historic trend to recognizing smaller, more discrete units. What has principally been fluid in rosaceous taxonomy until modern molecular research are the phylogenetic relationships, both to neighboring families and within the family. Rosales once contained families such as Crassulaceae and Saxifragaceae, which have many morphological similarities to Rosaceae, but Angiosperm Phylogeny Group (2003) indicated instead that in Rosales, Rosaceae is sister to a group of families including Moraceae, Rhamnaceae, Ulmaceae, and Urticaceae.<p><p>The internal relationships of Rosaceae have received much study, including morphological, anatomical, cytological, phytochemical, breeding system, fungal pathogenicity (especially rusts), and molecular. Among these studies, that of D. Potter et al. (2007) resulted in the first comprehensive molecular phylogeny of Rosaceae, and the treatment in this volume reflects it. Potter et al. recognized three subfamilies with 15 tribes worldwide. Their classification used the ranks supertribe and subtribe, not used here. The subfam. Dryadoideae, with one tribe and four genera, diverged early and is unique in Rosaceae for its actinorhizal symbiosis; it has achenaceous fruits. Subfamily Rosoideae has six tribes and 29 genera and is only slightly altered from its traditional circumscription by shedding Dryadoideae and three small genera. Most Rosoideae have achenaceous fruit; some have multiple drupelets or achenes borne on a torus. The remainders of Rosaceae are found in the large and heterogeneous subfam. Amygdaloideae of nine tribes and 54 genera. This subfamily has the largest diversity of fruit types. Amygdaloideae now contains the traditional spiraeoid genera with follicular fruit, Maleae with pome fruit, and Amygdaleae with drupaceous fruit.<p> <p> SELECTED REFERENCES Kalkman, C. 1988.
