Question: can both Diospyros and Erythrina be trees?
Context: Diospyros is a genus of over 700 species of deciduous and evergreen trees and shrubs.  The majority are native to the tropics, with only a few species extending into temperate regions.  Depending on their nature, individual species are commonly known as ebony or persimmon trees.  Some are valued for their hard, heavy, dark timber, and some for their fruit.  Some are useful as ornamentals and many are of local ecological importance. Erythrina schliebenii is a species of legume in the Fabaceae family.  It is found only in Tanzania.  Believed to have gone extinct in 2008 when the only known surviving trees fell victim to commercial logging, a small population of fewer than 50 individual trees was rediscovered in March 2012 during botanical explorations in the south-east of Tanzania. Nothocestrum breviflorum, commonly known as smallflower ʻ aiea, is a species of tree in the nightshade family, Solanaceae, that is endemic to the island of Hawaiʻ i.  It inhabits dry and mixed mesic forests at elevations of 180 - .  These forests are dominated by ʻ ōhiʻ a lehua ("Metrosideros polymorpha") and koa ("Acacia koa") or lama ("Diospyros sandwicensis"), while plants associated with smallflower ʻ aiea include wiliwili ("Erythrina sandwicensis") and uhiuhi ("Caesalpinia kavaiensis").  "N. breviflorum" reaches a height of 10 - .  It is threatened by habitat loss.  It is federally listed as an endangered species of the United States.  There are fewer than 50 individuals remaining. The persimmon (sometimes spelled persimon) is the edible fruit of a number of species of trees in the genus "Diospyros".  The most widely cultivated of these is the Oriental or Japanese persimmon, "Diospyros kaki".  "Diospyros" is in the family Ebenaceae, and a number of non-persimmon species of the genus are grown for ebony timber. The Hawaiian tropical dry forests are a tropical dry broadleaf forest ecoregion in the Hawaiian Islands.  They cover an area of 6600 km2 on the leeward side of the main islands and the summits of Niʻ ihau and Kahoʻ olawe.  These forests are either seasonal or sclerophyllous.  Annual rainfall is less than 127 cm and may be as low as 25 cm ; the rainy season lasts from November to March.  Dominant tree species include koa ("Acacia koa"), koaiʻ a ("A. koaia"), ʻ akoko ("Euphorbia" spp.) , ʻ ōhiʻ a lehua ("Metrosideros polymorpha"), lonomea ("Sapindus oahuensis"), māmane ("Sophora chrysophylla"), loulu ("Pritchardia" spp.) , lama ("Diospyros sandwicensis"), olopua ("Nestegis sandwicensis"), wiliwili ("Erythrina sandwicensis"), and ʻ iliahi ("Santalum" spp.) .  Endemic plant species in the dry forests include hau heleʻ ula ("Kokia cookei"), uhiuhi ("Caesalpinia kavaiensis"), and "Gouania" spp.  The palila ("Loxioides bailleui"), a Hawaiian honeycreeper, is restricted to this type of habitat. Diospyros candolleana, is a tree in the Ebony family, endemic to the Western Ghats of India and Sri Lanka.  The trees are usually 20m tall, and found as subcanopy trees in wet evergreen forests up to 90m. Erythrina is a genus of flowering plants in the pea family, Fabaceae.  It contains about 130 species, which are distributed in tropical and subtropical regions worldwide.  They are trees, growing up to 30 m in height.  The generic name is derived from the Greek word ερυθρóς ("erythros"), meaning "red," referring to the flower color of certain species. Gasparito is a village on the island of Aruba, located towards the northwestern end of the island.  The name of the area where we are located and the name of our Restaurant-Art Gallery.  In the past, areas and properties were named after the families who owned the land.  Our ancestors were Arawak and Europeans, therefore the areas on the Island have distinct Native and European names.  Gasparitos are beautiful, deep red, dagger shaped flowers that people boil and serve in scrambled eggs, beans, and various other dishes.  The scientific name is Erythrina americana, a member of Coral Trees. Samsonia is a genus of Gram-negative bacteria in the family Enterobacteriaceae.  Species within this genus were originally found in the bark of diseased Erythrina trees.  Among bacterial plant pathogens within the Enterobacteriaceae, "Samsonia" species may be most closely related to "Pectobacterium" species.  Up to now there is only one species of this genus known ("Samsonia erythrinae"). Diospyros discolor (commonly known as velvet apple, velvet persimmon or mabola tree) is a tree of the genus "Diospyros" of ebony trees and persimmons. Its edible fruit has a skin covered in a fine, velvety fur which is usually reddish-brown, and soft, creamy, pink flesh, with a taste and aroma comparable to fruit cream cheese.  It is native to the Philippines, where "kamagong" usually refers to the entire tree, and "mabolo" or "tálang" is applied to the fruit.  Velvet apple trees are found, but rare, in Sri Lanka too.
