“…The presence of polymorphic stomata in a single species is rare (PATEL & INAMDAR, 1971;GHOSH & BANERJI, 1981;SHARMA & SEN, 1969). The dimorphism of stomata in more than 200 species of dicotyledonous plants has been discussed by BOLDT & RANK (2011). METCALFE & CHALK (1950) mentioned rubiaceous (paracytic) stomata in the family Canellaceae.…”

“…However, in case of giant stomata the size attaines c. 7.2 × 2.16 µm and such stomata are scattered throughout the laminar surface instead of concentrating along the veins. Though CHANDRA et al (1969, SITHOLEY & PANDEY (1971), TRIVEDI & UPADHYAY (1974), JAIN & SINGH (1975), GHOSH & BANERJI (1981), BOLDT & RANK (2011) reported the existence of giant stomata in many species of angiosperms. However in the plant kingdom in general, particularly in angiospermous families, it is regarded as unusual.…”

Structure of Polymorphic Stomata in Canella winterena (L.) Geartn. (Canellaceae)

The presence of 10 types of normal stomata along with 4 subtypes, one intermediate type between stephanocytic and hemiparacytic and some abnormal stomatal structures both in the vegetative and floral organs of Canella winterena (L.) Geartn. (Canellaceae) is reported here. The epidermal cells are polygonal, isodiametric in surface view with straight anticlinal walls. The stomata are amphibrachyparacytic, anomocytic, anisocytic, brachyparacytic, brachyparatetracytic, cyclocytic, hemiparacytic, laterocytic, holoparacytic, stephanocytic, one intermediate type between stephanocytic and hemiparacytic, etc. Abnormalities like contiguous stomata, different types of twin stomata and cytoplasmic bridge between adjacent stomata, stomata with single guard cell, single guard cell with pore juxtaposed with normal stoma are also found. The presence of giant stomata is a significant finding. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

“…Position within the crown is also important; in North Bosnia and Herzegovina, Oljača, Govedar, and Hrkić () recorded stomatal density of 293–372 per mm 2 at edge of the crown in full light, and 169–230 per mm 2 on an inner, shaded part of the crown. Similarly, Boldt and Rank () found density to vary from 146 per mm 2 at the base of the crown to 321 per mm 2 in the middle and 322 per mm 2 at the top. Boldt and Rank () also found that stomata can vary in size within a leaf, with 3%–10% of the stomata being “giant”‐sized, reaching 25 to >40 μm long, mixed with those c .…”

Biological Flora of the British Isles:Aesculus hippocastanum

et al. 2019

View full text Add to dashboard Cite

This account presents information on all aspects of the biology of Aesculus hippocastanum L. (horse‐chestnut) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. Aesculus hippocastanum is a large deciduous tree native to the Balkan Peninsula. Native populations are small (<10,000 trees total) and apparently in decline, but the tree has been widely planted in gardens and streets across Europe and other temperate areas from the 17th century onwards. It was voted the UK's favourite tree in a 2017 poll. As a British neophyte, it is occasionally naturalised in open wooded habitats. Horse‐chestnut is renowned for the beauty of its large (up to 30 cm long), upright panicles of white flowers, and for the large seeds (up to 42 g each) used in the formerly common children's game of “conkers.” More recently, the triterpene glycosides, extractable from various plant parts but especially the seeds, have been widely used in medicine. In much of Europe, horse‐chestnut is affected by chestnut bleeding canker (caused by Pseudomonas syringae pv. aesculi), the horse‐chestnut leaf miner Cameraria ohridella and the leaf blotch fungus Guignardia aesculi. The canker is likely to lead to death of <10% individuals, but seeds of plants infested with the leaf miner are 40%–50% smaller, which may affect long‐term establishment in non‐planted areas.

The genus Iris L., comprising approximately 210 species, is one of the most species-rich genera in the family Iridaceae. In this study, the first comprehensive leaf micromorphological characters of Korean irises were studied using light and scanning electron microscopy. Our objective was to evaluate the foliar micromorphological characteristics (namely epidermal cells, stomata types, and guard cell size) of Korean Iris taxa in a systematic context. All the investigated Korean Iris taxa had amphistomatic or hypostomatic leaves with anomocytic stomatal complexes. Guard cell length varied among species, ranging from 24.8 μm (I. rossii) to 56.0 μm (I. domestica). Although the presence of papillae on the outer periclinal wall is not of taxonomic significance, leaf margin pattern, guard cell size, and sunken stomata type were useful for species-level identification of Korean Iris species. The occurrence of polymorphic stomatal types was reported here for the first time, and the correlation between genome size and epidermal guard cell length was discussed.
