Structure and developmental processes were studied in a Quercus mongolica Fisch. var. grosseserrata (Bl.) Rehd. et Wils. forest in the Fagetea crenatae Bl. region in Japan. The Quercus forest was classified into three stand types: stands dominated by Quercus with many species (type Q-MIX), Quercus-Fagus (type Q-F), and Quercus (type Q). In Q-MIX, Alnus hirsuta Turcz. had a bell-shaped DBH-class distribution. Most Quercus trees were single stemmed. The establishment of Quercus trees occurred continuously from the 1900s. The percentage of growth change (%GC) exhibited negative values from the 1940s. In Q-F and Q, Quercus trees had bell-shaped DBH-class distributions, and multiple-stemmed trees showed broad distributions. In Q-F, tree establishment peak was in the 1870s. %GC exhibited large fluctuations. In Q, tree establishment peak was in the 1850s. %GC exhibited negative values for 60 years. In conclusion, type Q-MIX, Q-F, and Q developed mainly by seedling regeneration following major cutting in the 1900s, sprout and seedling regeneration following intermittent cuttings mainly in the 1870s, and sprout and seedling regeneration following successive cuttings mainly in the 1850s, respectively. Cutting disturbance can be a major factor in developmental processes in Quercus forest; the frequency and intensity of cuttings affect the stand structure and the dominance of Quercus in the Fagetea crenatae region.

A new species of Vernonia (Asteraceae, Vernonieae) is described from mountain cloud forest, Pinus forest and Pinus–Quercus forest in the State of Oaxaca, Mexico. Typical characters of this species are the lax corymbiform inflorescences, formed by 3–10 heads on peduncles > 4.5 cm long, and the lanceolate or elliptic-ovate shape of leaves. A key to the Mexican species of Vernonia is included.

We praise the authors for their work, and for the lyric title of their paper. We give a concise sketch of the present level of understanding of Quercus forest in Colombia. We identify the shortcomings in this published paper. We improve the relevance of this paper about Quercus as well as for future phylogenetic investigations other montane forest taxa to be framed in the rapidly improving palaeoecological understanding of the Northern Andes.
