Question: What is the difference between Stachyurus and Cucumis?

full_context: Document 1: Stewartia: Stewartia (sometimes spelled Stuartia) is a genus of 8-20 species of flowering plants in the family Theaceae, related to "Camellia". Most of the species are native to eastern Asia in China, Japan, Korea, Laos, Myanmar, Thailand, and Vietnam, with two ("S. malacodendron, S. ovata") in southeast North America, from Virginia and Kentucky south to Florida and Louisiana.
Document 2: Orostachys: Orostachys is a genus of Crassulaceae that contains 14 accepted species. It is a biennial herb growing in China, Japan, Kazakhstan, Korea, Mongolia, Russia. Eight species occur in China.
Document 3: Sphingomonas melonis: Sphingomonas melonis is a bacterium from the genus of Sphingomonas which has been isolated from the plant Cucumis melo var. inodorus in Madrid in Spain. "Sphingomonas melonis" can cause brown spots on melon fruits from the melon plant (Cucumis melo var. inodorus).
Document 4: Melon soup: Melon soup is a soup prepared with melon as a primary ingredient. Melons such as bitter melon, cantaloupe, crenshaw melon, honeydew (casaba melon) and winter melon may be used, among others. Some melon soups are prepared with whole pieces of melon, and others use puréed melon. Some are served hot, while others are served chilled. Some cold varieties are prepared without any cooking involved. Several styles and varieties of melon soups exist, including bitter melon soup, cantaloupe soup and winter melon soup, among others. The origin of some melon soup recipes may cross international boundaries.
Document 5: Squash bee: The name squash bee, also squash and gourd bee, is applied to two related genera of bees in the tribe Eucerini; "Peponapis" and "Xenoglossa". Both genera are oligoleges (pollen specialists) on the plant genus "Cucurbita" and closely related plants, such as cucumbers. They are small genera, containing only 13 and seven described species, respectively, and their combined range is nearly identical to the range of "Cucurbita" in the New World, from South America to North America. Their range has become somewhat expanded along with the movement of cucurbits into other areas (as crop plants). These bees are of moderate size, equal to various bumblebees. The pollen-carrying hairs on their legs (the scopa) are unbranched or nearly so, and sparse, to accommodate the exceptionally large, coarse pollen of the host plants. They have also evolved a matinal daily activity cycle, flying before sunrise. Some "Xenoglossa" species have become morphologically specialized to fly while it is still dark, with greatly enlarged ocelli to allow them to fly in near-darkness.
Document 6: Strobilanthes: Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their 2-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.
Document 7: Acanthosicyos: Acanthosicyos is a genus of thorny shrubs of the botanical family Cucurbitaceae, subfamily Cucurbitoideae. The genus name derives from the Greek words ""akantha"" for thorn and ""sykios"" for cucumber or gourd. Endemic to the Namib Desert in Africa, this genus is represented by two known species including "Acanthosicyos horridus", the nara melon, an important food plant in its native range.
Document 8: Pachystachys: Pachystachys is a genus of 12 species of flowering plants in the family Acanthaceae, native to rainforest in the Caribbean and Central and South America. They are evergreen perennials and shrubs bearing prominent terminal spikes of flowers with brightly coloured bracts.
Document 9: Dichroa: Dichroa is a genus of 12 species of flowering plants in the family Hydrangeaceae, native to eastern and southeastern Asia. They are deciduous shrubs growing to 1-3 m tall, with their leaves arranged in opposite pairs. The flowers are produced in a broad inflorescence similar to that of the related genus "Hydrangea". The fruit is a glossy metallic purple-blue berry.
Document 10: Stachyurus praecox var. matsuzakii: Stachyurus praecox" var. "matsuzakii (Hachijō-kibushi, ハチジョウキブシ), is a variety of "Stachyurus praecox", and is only found in Japan. Compared to the other "Stachyurus praecox" varieties, this variety has thicker branches, longer inflorescences, and larger fruits.
Document 11: Cucumis (website): Cucumis is a website where translators share their linguistic knowledge and exchange services online. One unusual feature of Cucumis is that all translations are peer reviewed and may be edited by other Cucumis translators. This provides for high quality translations, and often achieves a target text that is both faithful in meaning to the source text and fully idiomatic in the target language.
Document 12: Tromboncino (squash): Tromboncino (] ), also known as zucchetta (] ), is a type of squash most often used as a summer squash. While nearly all summer squash are cultivars of "Cucurbita pepo", tromboncino is a cultivar of "Cucurbita moschata". The vining growth habit, is similar to many winter squashes, but unlike most other summer squash. It is more tolerant to some common summer squash pests, including squash vine borer, squash bugs, and powdery mildew, than the more commonly grown, bushy, "C. pepo" summer squash cultivars. The plants are slower to start producing than some "C. pepo" types. The fruit color is usually pale green, fading to beige upon maturity, and it is picked around one foot long for summer squash. It is an heirloom, originally from Liguria, and remains popular throughout Italy and abroad. Tromboncino squash can be left to mature into a winter squash; such is often compared to a watery butternut squash. If left to ripen, the fruits can grow over three feet in length.
Document 13: Cucumis: Cucumis is a genus of twining, tendril-bearing plants in the Cucurbitaceae family which includes the cucumber ("Cucumis sativus"), muskmelons ("Cucumis melo", including cantaloupe and honeydew), the horned melon ("Cucumis metuliferus"), and the West Indian gherkin ("Cucumis anguria").
Document 14: Stachyurus: Stachyurus is the only genus in the flowering plant family Stachyuraceae, native to the Himalayas and eastern Asia. They are deciduous shrubs or small trees with pendent racemes of 4-petalled flowers which appear on the bare branches before the leaves. The plants have leaves with serrate margins. Stachyuraceae contains a single genus with eight species.
Document 15: Stephanandra: Stephanandra is a genus in the family Rosaceae that is sometimes included in the genus "Neillia". The deciduous, thicket-forming shrubs have attractive wavy-margined leaves that resemble maple leaves and have a good orange-yellow fall color. Cutleaf "Stephanandra" grows to less than 2 feet tall but spreads by suckering. In winter it has rich brown, arching shoots. It grows in full sun. The fruits of "Stephanandra" are dry dehiscent fruits.
ground_truth: Stachyuraceae contains a single genus with eight species.
