In many treatments (e.g., E. G. Voss 1972+, vol. 2), Quercus ellipsoidalis is included in Q . coccinea . Variation in fruit morphology has led to recognition of several formae (W. Trelease 1919; see also R. J. Jensen 1986) and one variety ( Q . ellipsoidalis var. kaposianensis , based on specimens from St. Paul, Minnesota, in which the cup tightly encloses the nut for two-thirds its length at maturity).
Quercus ellipsoidalis reportedly hybridizes with Q . rubra and Q . velutina .
The Menominee used Quercus ellipsoidalis medicinally to treat suppressed menses caused by cold (D. E. Moerman 1986).

treeNorthern pin oak is a small to medium-sized, native, deciduous tree,
typically reaching heights to 70 feet (21 m) [

wikipedia CA tarafından sağlandı
Quercus ellipsoidalis és una espècie de roure que pertany a la família de les Fagàcies i està dins de la secció Lobatae, dins del gènere Quercus. És originària de l'Amèrica del Nord.
Descripció
És un arbre caducifoli de grandària mitjana que pot arribar a créixer fins als 20 m d'alçada i forma una capçada rodona i oberta. Les seves fulles són lluents, de color verd i fan entre 7 i 13 cm de llarg per 5 a 10 cm d'ample, lobades, amb cinc o set lòbuls separats per profunds buits entre ells i que al seu torn cada un d'aquests lòbuls té entre 3 i 7 dents punxegudes. Les fulles gairebé no tenen vellositats, llevat de petits flocs de color taronja pàl·lid o cafè on s'uneixen les venes dels lòbuls amb la vena central. Les glans tendeixen a ser de forma el·líptica, i d'allí prové el nom científic d'aquesta espècie, encara que tendeixen a ser de formes molt variables i tendeixen a ser globoses, de 6 a 11 mm de llarg i 10 a 19 mm d'ample, amb la seva cúpula que recobreix a la gla entre la tercera part o fins i tot fins a la meitat. Aquestes glans quan maduren, aproximadament després de 18 mesos després de la pol·linització, són d'un color verd marró pàl·lid i de sabor molt amarg. La superfície interna de la tapa de les glans és glabra (sense pèls) o moderadament pubescents, i els pèls, si és que estan presents, tendeixen a ser arrissats en lloc de rectes.
Distribució i hàbitat
Principalment es desenvolupa a la zona nord del Mig Oest dels Estats Units, i també al sud-est i sud-oest d'Ontàrio a Canadà. Preferentment es desenvolupa en sòls secs, arenosos i en general en sòls àcids. Encara que el seu nom en anglès "Northern Pin Oak" suggereix algun tipus de semblança amb el "Pin Oak" (Quercus palustris), aquest en realitat tradicionalment ha estat relacionat estretament amb Quercus coccinea i de fet va ser inclòs dins d'aquesta espècie per diversos botànics. Però treballs recents suggereixen que Quercus ellipsoidalis està més relacionat amb Quercus velutina conegut com a roure negre i que pot existir alguna correlació entre els gens d'aquestes dues espècies.[1] La similitud morfològica entre Q. ellipsoidalis i Q. coccinea segueix sent una font de confusió, sobretot al nord-est d'Indiana i el sud del Comtat de Cook a Illinois.
Usos
Ocasionalment Quercus ellipsoidalis és plantat com un arbre ornamental, molt popular pel color vermell brillant de les seves fulles a la tardor, i per la seva tolerància als sòls sorrencs i infèrtils. El seu tronc és massa petit per ser aprofitat com a fusta, però és similar a la d'altres "roures vermells".

Quercus ellipsoidalis
(
İngilizce
)
wikipedia EN tarafından sağlandı
Quercus ellipsoidalis, the northern pin oak or Hill's oak, is a North American species of oak tree native to the north-central United States and south-central Canada, primarily in the Great Lakes region and the Upper Mississippi Valley.[2] It most commonly occurs on dry, sandy soils.[3]
Description
Quercus ellipsoidalis is a medium-sized deciduous tree growing to 20 meters (66 feet) tall with an open, rounded crown. The leaves are glossy green, 7–13 centimetres (2+3⁄4–5 inches) long and 5–10 cm (2–4 in) broad, lobed, with five or seven lobes, and deep sinuses between the lobes. Each lobe has 3–7 bristle-tipped teeth. The leaf is nearly hairless, except for small tufts of pale orange-brown down where the lobe veins join the central vein. The acorns tend to be ellipsoid (ellipse-shaped, from which its scientific name derives), though they tend to be highly variable and range to globose, 6–11 millimetres (1⁄4–7⁄16 in) long and 10–19 mm (13⁄32–3⁄4 in) broad, a third to a half covered in a deep cup, green maturing pale brown about 18 months after pollination; the kernel is very bitter. The inner surface of the acorn cap is glabrous (hairless) to sparsely or moderately pubescent, and the hairs if present tend to be kinky rather than straight.[4][5]
Taxonomy
Although the common name suggests a resemblance to the pin oak (Q. palustris), Q. ellipsoidalis has traditionally been thought to be closely related to the scarlet oak (Q. coccinea), and was in fact included in that species by many botanists. Recent work suggests that there is more gene flow between Hill's oak and black oak (Q. velutina), but the phylogenetic position of these species is still uncertain.[6] The morphological similarity between Q. ellipsoidalis and Q. coccinea remains a source of confusion, especially in northwestern Indiana and southern Cook County, Illinois.[6][7]
Uses
Northern pin oak is planted as an ornamental tree, popular for its bright red fall color and tolerance of infertile sandy soils. The wood is used for fence posts, fuel and general construction. The cultivar 'Hemelrijk' has gained the Royal Horticultural Society's Award of Garden Merit.[8][9]

Descripción
El roble de Hill es un árbol caducifolio de tamaño mediano que llega a crecer hasta los 20 m de altura y forma una corona redonda y abierta. Sus hojas son lustrosas, de color verde y miden entre 7 y 13 cm de largo por 5 a 10 cm de ancho, lobadas, con cinco o siete lóbulos separados por profundos huecos entre ellos y que a su vez cada uno de estos lóbulos tiene entre 3 y 7 dientes puntiagudos. La hoja casi no tienen bellos, a excepción de pequeños mechones de color naranja pálido o café donde se unen las venas de los lóbulos con la vena central. Las bellotas tienden a ser de forma elíptica, y de allí proviene el nombre científico de esta especie, aunque tienden a ser de formas muy variables y tienden a ser globosas, de 6 a 11 mm de largo y 10 a 19 mm de ancho, con su cúpula que recuble a la bellota entre la tercera parte o incluso hasta la mitad. Estas bellotas cuando maduran, aproximadamente luego de 18 meses después de polinización, son de un color verde marrón pálido y de sabor muy amargo. La superficie interna de la tapa de las bellota es glabra (sin pelos) o moderadamente pubescentes, y los pelos, si es que están presentes, tienden a ser rizados en lugar de rectos.
Distribución y hábitat
Principalmente se desarrolla en la zona norte del Medio Oeste de Estados Unidos, y también en el sur este y sur oeste de Ontario en Canadá. Preferentemente se desarrolla en suelos secos, arenosos y por lo general en suelos ácidos. Aunque su nombre en inglés "Northern Pin Oak" sugiere algún tipo de parecido con el "Pin Oak" (Quercus palustris, éste en realidad tradicionalmente ha sido relacionado estrechamente con el Quercus coccinea y de hecho fue incluido dentro de esta especie por varios botánicos. Sin embargo trabajos recientes sugieren que el roble de Hill está más relacionado con el Quercus velutina conocido como roble negro y que puede existir alguna correlación entre los genes de estas dos especies.[3] La similitud morfológica entre Q. ellipsoidalis y Q. coccinea sigue siendo una fuente de confusión, sobre todo en el noroeste de Indiana y el sur del Condado de Cook en Illinois.
Usos
El roble de Hill ocasionalmente es plantado como un árbol ornamental, muy popular por el color rojo brillante de sus hojas en otoño, y por su tolerancia a los suelos arenosos e infértiles. Su tronco es demasiado pequeño para ser aprochado como madera, pero es similar a la de otros "robles rojos".
Taxonomía
Quercus ellipsoidalis fue descrita por Ellsworth Jerome Hill y publicado en Botanical Gazette 27(3): 204–208, pl. 2–3. 1899.[4]
