& Penas, A.--1999--A new nothospecies of the genus Quercus
In Mexico, the three sections of genus Quercus subgenus Quercus are well-represented (Nixon, 1993).
Analyses using scanning electron microscopy (SEM) were performed on mature leaves of 27 taxa of the genus Quercus sampled in 11 states of Mexico (Table 1).
Thus, if we want to recognize subgenus Cyclobalanopsis of genus Quercus
, we must also recognize subgenus Quercus, with at a minimum Quercus robur (the type of Quercus).
Hint: Hagrid's wand is from a tree belonging to the genus Quercus
The latter value was largely determined by the genus Quercus
which comprised nearly half of the species in the subclass and where nearly all species are thought to hybridize.
Abstract: We describe the habitat of species within the Fagaceae subgenus Lepidobalanus (genus Quercus
) and identify environmental variables related to their distribution in the Meseta Central of Chiapas, Southern Mexico.
(1994) tested these hypotheses with the genus Quercus
, using long-term data sets.
The genus Quercus
is the source of what is called true oaks.
Most of polypores which are parasitic upon oaks in local oakeries [1-3] are met on species of genus Quercus
All species of Disholcaspis induce detachable stem galls on white oaks (section Quercus of the genus Quercus
L.; Fagales: Fagaceae), with the exception of the Californian species, D.
Since Darwin (1859), the genus Quercus
has attracted the attention of evolutionists for its very poor development of reproductive barriers between species (Grant 1981; Rushton 1993).
Silky oak is often written in quotation marks because the tree is not considered a true oak of the genus Quercus
. Lacewood sold commercially in the United States also includes the related species Grevillea robusta, known also as southern silky oak, both of the family Proteaceae.
(2001) correlated foliar damage with a decrease in insect diversity, although other studies conducted on the genus Quercus
did not see such an effect (Hunter & Forkner 1999).
