For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the Mountain Strawberry, we have 373 observations. Compared to other species in this Class, this species is moderately common.
A two-sample t-test can be used to determine whether the trend in observations of the Mountain Strawberry is the same as the trend in observations of Magnoliopsida. Is this species just as common, as a proportion of all observations, as it once was? The answer is no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=5.342, p<0.001)
How do observation rates of the Mountain Strawberry differ from those of Magnoliopsida? To answer this, we examined the percentage of observerations for Magnoliopsida that were observations of the Mountain Strawberry each year. We then correlated this percentage with observation year. If observations of the Mountain Strawberry are becoming more common relative to other species of Magnoliopsida, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.36), with a negative slope (m = -.000), suggesting that the Mountain Strawberry may be in decline relative to other species of Magnoliopsida. This correlation is statistically significant. (F = 43.96, p<.05)
The scatter chart to the right shows the percentage of all observations for Magnoliopsida each year that were observations of the Mountain Strawberry.
Trees, shrubs, or herbs, deciduous or evergreen.Stemserect, scandent, arching, prostrate, or creeping, armed or unarmed.Buds usually with several exposed scales, sometimes with only 2. Leaves alternate, rarely opposite, simple or compound; stipulespaired, free or adnate to petiole, rarely absent, persistent or deciduous; petiole usually 2-glandular apically; leafblade often serrate at margin, rarely entire.Inflorescences various, from single flowers to umbellate, corymbose, racemose or cymose-paniculate. Flowers usually actinomorphic, bisexual, rarely unisexual and then plantsdioecious.Hypanthium (formed from basal parts of sepals, petals, and stamens) free from or adnate to ovary, short or elongate. Sepals usually 5, rarely fewer or more, imbricate; epicalyxsegments sometimes also present. Petals as many as sepals, inserted below margin of disk, free, imbricate,
sometimes absent. Disk lining hypanthium, usually entire, rarely lobed. Stamens usually numerous, rarely few, always in a completering at margin of or above disk; filaments usually free, very rarely connate; anthers small, didymous, rarely elongate, 2-locular. Carpels 1 to many, free, or ± connate and then adnate to inner surface of cupularreceptacle; ovary inferior, semi-inferior, or superior; ovules usually 2 in each carpel, rarely 1 or several, anatropous, superposed.Styles as many as carpels, terminal, lateral, or basal, free or sometimes connate.Fruit a follicle, pome, achene, or drupe, rarely a capsule, naked or enclosed in persistent hypanthium and sometimes also by sepals. Seeds erect or pendulous, sometimes winged, usually exalbuminous, very rarely with thin endosperm; cotyledons mostly fleshy and convexabaxially, rarely folded or convolute.
Between 95 and 125 genera and 2825-3500 species: cosmopolitan, mostly in N temperate zone; 55 genera (two endemic) and 950 species (546 endemic) in China.
Many plants of this family are of economic importance and contribute to people s livelihoods. The Rosaceae contain a great number of fruit trees of temperate regions. The fruits contain vitamins, acids, and sugars and can be used both raw and for making preserves, jam, jelly, candy, various drinks, wine, vinegar, etc. The dried fruits of the genera
Amygdalus and Armeniaca are of high commercial value. Some plants in the genusRosa containing essential oils or with a high vitamin content are used in industry. Rosaceae wood is used for making various articles, stems and roots are used for making tannin extract, and young leaves are used as a substitute for tea. Numerous species are used for medical purposes or are cultivated as ornamentals.
The Rosaceae are very well represented in China, with great economic and scientific importance. The Co-chairs of the Editorial Committee (Wu and Raven) here note that the patterns of relationship are complex and the group is taxonomically difficult. [1]
Genus Fragaria:
Herbs perennial, mostly stoloniferous, polygamo-dioecious, usually spreading or appressedhairy.Stolons often rooting at nodes and forming plantlets. Leaves alternate, petiolate; stipulesadnate to base of petiole, often membranous, sheathing; leafblade 3-foliolate or pinnately 5-foliolate. Inflorescenceerect, cymose or corymbiform, few flowered, rarely a solitary flower.Hypanthiumobconic or turbinate.Sepals 5, valvate, persistent; epicalyxsegments 5, alternating with and smaller than sepals, marginentire.Petals 5, white, rarely yellow, broadly obovate or suborbicular.Stamensnumerous; anther 2-loculed. Carpels numerous, free, borne on convexreceptacle; ovuleascending from middle of locule; styleadaxial, short, persistent.Aggregate fruit formed from enlarged receptacle, berry-like, long conic to globose, fleshy.Achenes numerous,
seated in pits on surface of aggregate fruit, minute, brittle. Seedtesta membranous; cotyledonsconvex.x = 7.
About 20 species: temperate and subtropical regions of N hemisphere, extending to South America; nine species (three endemic, one introduced) in China.[2]
