Highly variable shrub or small tree indigenous to Hawaii and widespread in the Pacific. Fruits about half an inch long, 2-4 winged, reddish purple. The fruit and leaves are commonly used in lei construction.
For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the Florida Hopbush, we have 1,569 observations. Compared to other species in this Class, this species is extremely common.
A two-sample t-test can be used to determine whether the trend in observations of the Florida Hopbush 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=22.47, p<0.001)
How do observation rates of the Florida Hopbush differ from those of Magnoliopsida? To answer this, we examined the percentage of observerations for Magnoliopsida that were observations of the Florida Hopbush each year. We then correlated this percentage with observation year. If observations of the Florida Hopbush 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=-.81), with a negative slope (m = -.002), suggesting that the Florida Hopbush may be in decline relative to other species of Magnoliopsida. This correlation is statistically significant. (F = 88.57, p<.05)
The scatter chart to the right shows the percentage of all observations for Magnoliopsida each year that were observations of the Florida Hopbush.
Trees or shrubs (or woody vines with tendrils in Cardiospermum and allied genera), rarely herbaceous climbers. Indumentum usually of simplehairs, often glandular on young parts, buds, and inflorescences. Leaves alternate, usually estipulate; leafbladepinnate or digitate, rarely simple; leaflets alternate to opposite, entire or dentate to serrate.Inflorescence a terminal or axillarythyrse; bracts and bracteoles small. Flowersunisexual, rarely polygamous or bisexual, actinomorphic or zygomorphic, usually small. Sepals 4 or 5(or 6), equal or unequal, free or connate at base, imbricate or valvate.Petals 4 or 5(or 6), sometimes absent, free, imbricate, usually clawed, often with scales or hair-tufted basal appendages. Diskconspicuous, fleshy, complete or interrupted, lobed or annular, rarely absent. Stamens 5-10(-74), usually 8, rarely numerous, variously inserted but usually within disk, often exserted in male flowers; filaments free, rarely connate; anthersdorsifixed, longitudinally dehiscent, introrse; staminodes sometimes present in carpellate flowers, but filaments shorter and anthers with a thick wall, indehiscent.Ovarysuperior, (1-) 3(or 4) -loculed; ovules 1 or 2(or several) per locule, placentationaxile, rarely parietal, anatropous, campylotropous, or amphitropous; style usually apical (terminal), semigynobasic in Allophylus [gynobasic in Deinbollia Schumacher & Thonning]; stigma entire or 2 or 3(or 4) -lobed, usually rudimentary in male flowers. Fruit a loculicidalcapsule, berry, or drupe, or consisting of 2 or 3 samaras, often 1-seeded and 1-loculed by abortion.Seeds 1(or 2 or more) per locule; testa black or brown, hard, often with a conspicuous fleshy aril or sarcotesta; embryocurved, plicate, or twisted, oily and starchy; endosperm usually absent. 2n = 20-36.
One hundred thirty-five genera and ca. 1500 species: widely distributed in tropical and subtropical regions, especially well represented in tropical SE Asia; 21 genera (one endemic) and 52 species (16 endemic, one introduced) in China.
There is some variation in the circumscription of Sapindaceae in taxonomic treatments, particularly with regard to the inclusion of genera from the closely related, predominately temperate families Aceraceae and Hippocastanaceae. Several studies including Müller and Leenhouts (in Ferguson & Müller, Evolutionary Significance Exine: 407-445. 1976), and more recently those based on molecular data (Stevens, AngiospermPhylogeny Website, 2001 onward; Harrington et al., Syst. Bot. 30: 366-382. 2005), supported the recognition of a broadly defined Sapindaceae incorporating Aceraceae and Hippocastanaceae. Harrington
et al. (loc. cit.) proposed four subfamilies or clades, comprising Sapindoideae (including
Koelreuteria and Ungnadia Endlicher), Dodonaeoideae, Hippocastanoideae (including taxa previously referred to Aceraceae and Hippocastanaceae, plus Handeliodendron), and a monotypic "Xanthoceratoideae". Within Hippocastanoideae, Acer Linnaeus and Dipteronia Oliver comprise a monophyletic group and are treated in this Flora as Aceraceae. Similarly, Aesculus Linnaeus, Billia
Peyritsch, and the Chinese endemic Handeliodendron Rehder form a monophyletic group and are treated here as Hippocastanaceae. There is some support for "Xanthoceratoideae" being the first lineage to diverge within the broadly defined Sapindaceae assemblage; consequently, Xanthoceras is treated separately from genera in Sapindoideae and Dodonaeoideae in the following account of Sapindaceae s.s. The sequence of genera reflects Müller and Leenhouts (loc. cit.) as modified by recent analyses based on molecular and morphological data, rather than following the order developed by Radlkofer (Sitzungsber. Math.-Phys. Cl. Königl. Bayer. Akad. Wiss. München 20: 105-379. 1890; and in Engler, Pflanzenreich 98a-h(IV. 165) : 1-1539. 1931-1934), which was previously followed in FRPS.
The main economic uses of this family include (1) timber: Amesiodendron chinense, Dimocarpus longan, D. confinis,Litchi chinensis, Pavieasia kwangsiensis, and Pometia pinnata; (2) fruit: Dimocarpus longan, Litchi chinensis, and Nephelium lappaceum; (3) medicine: Dimocarpus longan (arillode), Litchi chinensis (seeds), and Sapindus saponaria (roots) ; (4) oil: Amesiodendron chinense, Delavaya toxocarpa, and Xanthoceras sorbifolium. Saponins occur widely in the family, commonly used as a fish poison and for their detergent properties.[1]
Genus Dodonaea:

Stamens (male flowers) 5-8; filaments short; anthersellipsoid, obtusely 4-gonous, connectivesprominent.Ovary (female flowers) ellipsoid, obcordiform, or transversely ellipsoid, 2- or 3(or 5 or 6) -gonous, 2- or 3(or 5 or 6) -loculed; ovules 2 per locule, one ascending, and one pendulous; styleapical, much longer than ovary, often twisted, deciduous; stigma 2-6-lobed. Capsules samaralike, 2- or 3(-6) -loculed, septifragal, boatlike. Seeds 1 or 2 per locule, obovoid, lenslike, or subglobose; testacrustaceous, arillode present or absent;
