Wintergreen ferns keep their leaves for an entire year before replacing them with new leaves in the spring. The overwintering leaves of Dryopteris intermedia provide carbon to the new leaves, and if these old leaves cannot become prostrate before winter via the hinge that develops at the base of the petiole, they are frost damaged and broken, which may affect the development of the new leaves in the subsequent year. I compared the vernal development of new leaves in D. intermedia between plants whose old leaves were intact and those whose petioles had been experimentally broken in the fall to determine the importance of the softening of the petiole-base in old leaves to the development of new leaves. Compared to the control, plants whose old leaves had broken petioles had a one-week delay in the development of their new leaves. This delay demonstrates that the evolutionary development of the petiole hinge may have been critical to the functional benefit associated with new leaf development in the wintergreen leaf habit in ferns.","PeriodicalId":50817,"journal":{"name":"American Fern Journal","volume":"111 1","pages":"110 - 116"},"PeriodicalIF":0.8,"publicationDate":"2021-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41737881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Platycerium plants circulating amongst hobbyists and growers under the common name Platycerium ‘Mount Lewis' is the same plant as the cultivar known as Platycerium ‘Venose Frond’, or, as it was later called, Platycerium willinckii var. venosum.

Morphological and molecular comparisons of this plant were made with members of the P. bifurcatum complex, particularly with P. bifurcatum and P. willinckii, to determine its true identity.

This study was carried out in the Gori Valley catchment of Uttarakhand, Western Himalaya, to document more fully the distribution and ecology of ferns and lycophytes at a montane site divided into 7 elevation sampling zones from 1,800–4,000 m (subtemperate to alpine) across a distance of approximately 30 km. A total of 16 families, 33 genera, and 92 species were found. Species richness, total species density ha–1, diversity, and Pielou's species evenness per elevation zone (m) were calculated for each zone. The data were used to evaluate three hypotheses addressing changes in density and species distribution in relation to the biogeographic and climatic conditions across the seven elevation sampling zones. Total density of ferns and lycophytes tended to decrease from Zone 1 toward Zone 7; although Zones 1-3 (sub-temperate) had clearly higher mean densities than those in Zones 5-7 (alpine). The highest density was found in Zone 1 (Lilam 1,800 m) and lowest density was found in Zone 6 (Burfu 3,450 m). After finding a significant difference among all mean densities for each elevation zone (p < 0.001), using a non-parametric Welch's ANOVA, a Games-Howell test for pairwise comparisons of the means showed that each of the mean densities for species in Zones 1 to 3 was significantly different from each of the species densities in Zones 5 to 7 (p < 0.05). The mean densities for Zone 4 were not significantly different from any of the other zonal mean densities (i.e., 1–3 and 5–7), suggesting that Zone 4 is a transitional zone between two end member Zones (1–3 and 5–7).","PeriodicalId":50817,"journal":{"name":"American Fern Journal","volume":"111 1","pages":"6 - 23"},"PeriodicalIF":0.8,"publicationDate":"2021-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49361221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
