Quercus manzanillana

Quercus manzanillana is a shrub in the genus Quercus indigenous to Mexico. It was described in 1924 by William Trelease. It is found in the Mexican state of Puebla. [1]

Description

The twigs of Quercus manzanillana measure about 2-3 mm in diameter. They are fluted and initially covered in a grayish, tomentulose coating. The buds are light brown, glabrous and glossy, ovoid in shape, and approximately 2 x 3 mm in size. [2]

The leaves of this oak species are deciduous and elliptical in shape. They are obtuse and exhibit a more or less cordate base. The leaf margins are typically entire or very obscurely repand towards the upper part. The leaves measure 2.5-3.5 cm in width and 5-8 cm in length. The upper leaf surface is essentially glabrous and somewhat glossy, while the lower surface is densely covered in a persistent rusty-tomentose pubescence. The leaves have approximately 10 pairs of looped veins, and the petiole is tomentulose and measures around 5 mm in length. [2]

Validity

According to Susana Valencia-A. in 2004, this species described by Trelease is not valid. They claim that Quercus manzanillana represents a hybrid between different oak species or a morphological variety of an existing species. In 2003, Zavala-Chavez proposed an alternative classification for Quercus manzanillana. According to Zavala-Chavez's research, this oak species could be considered a variety of Quercus deserticola . However, these proposals are not universally accepted, and the taxonomic relationship between Quercus manzanillana and other oak species requires additional investigation. [1]

<i>Quercus ellipsoidalis</i> Species of oak tree

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. It most commonly occurs on dry, sandy soils.

<i>Quercus chrysolepis</i> Species of oak tree

Quercus chrysolepis, commonly termed canyon live oak, canyon oak, golden cup oak or maul oak, is a North American species of evergreen oak that is found in Mexico and in the western United States, notably in the California Coast Ranges. This tree is often found near creeks and drainage swales growing in moist cool microhabitats. Its leaves are a glossy dark green on the upper surface with prominent spines; a further identification arises from the leaves of canyon live oak being geometrically flat.

<i>Quercus durata</i> Species of oak tree

Quercus durata, commonly known as leather oak, is a species of oak endemic to California, common in the Coast Ranges and the foothills of the Sierra Nevada. The common name "leather oak" is derived from the leathery texture on the lop of its leaves. Taxonomically it is placed in the white oak group.

<i>Cephalotaxus fortunei</i> Species of conifer

Cephalotaxus fortunei, commonly called the Chinese plum-yew, Fortune's yew plum, simply plum yew, Chinese cowtail pine or in Chinese as san jian shan, is a coniferous shrub or small tree in the family Taxaceae. It is native to northern Burma and China, but is sometimes grown in western gardens where it has been in cultivation since 1848.

<i>Commelina diffusa</i> Species of flowering plant

Commelina diffusa, sometimes known as the climbing dayflower or spreading dayflower, is a pantropical herbaceous plant in the dayflower family. It has been introduced to the southeastern United States where it is most common in wet disturbed soils. There are two recognised varieties, one being the type and the other being C. diffusa var. gigas, which is native to Asia and has been introduced to Florida. It flowers from spring to fall and is most common in disturbed situations, moist places and forests. In China the plant is used medicinally as a febrifuge and a diuretic. A blue dye is also extracted from the flower for paints. In the Hawaiian Islands, it is known as "honohono grass", although it is technically not a grass. "Honohono" refers to the alternating structure of the leaves. At least one publication lists it as an edible plant in New Guinea.

<i>Quercus havardii</i> Species of oak tree

Quercus havardii is a deciduous, low-growing, thicket-forming shrub that occupies some two million to three million hectares in the southern Great Plains of North America. Clones may reach hundreds to thousands of years old, although aboveground stems typically live only 11 to 15 years. Shinnery oak stems are usually 1 to 2 metres tall and codominate the plant community with mid- and tall-grasses, which are usually taller than the oaks.

<i>Quercus sinuata <span style="font-style:normal;">var.</span> breviloba</i> Variety of a species of oak tree

Quercus sinuatavar. breviloba, commonly called Bigelow oak or Bigelow's oak, is a variety of Quercus sinuata, a species of oak tree that grows in parts of the southern United States and northeastern Mexico. Common names for this taxon are shallow-lobed oak, white shin oak, scaly-bark oak, limestone Durand oak, and shortlobe oak. The less specific common name bastard oak may refer to either of the two varieties of Quercus sinuata, var. sinuata and var. breviloba. Other common names include scrub oak or shin oak, but these names may refer to a number of other low growing, clump forming oak species, subspecies or varieties. For clear differentiation in common reference, American Forests uses Durand Oak to mean Quercus sinuata var. sinuata and Bigelow oak to mean Quercus sinuata var. breviloba, a shrubby variety of Quercus sinuata distinguished in part by its habit of forming clonal colonies in parts of its range.

Neuroterus numismalis is a gall wasp that forms chemically induced leaf galls on oak trees. It has both bisexual and agamic (parthenogenetic) generations and forms two distinct galls on oak leaves, the silk button gall and blister gall. The galls can be very numerous with more than a thousand per leaf.

<i>Quercus cornelius-mulleri</i> Species of tree

It can most easily be observed in Joshua Tree National Park and in the woodlands along the western margins of the Colorado Desert in San Diego County, California.
