Indicum has 2 variations, especially in terms of flowers, namely elongated and rounded types with antioxidant effects. So the aim this research is to know C. leaves, one varieties Banjar, Banjarbaru Tanah Laut areas, that variety indicum varr.M. Antioxidant testing using TLC quantitative UV-Vis spectrophotometer. The results qualitatively have activity marked by a yellowish white stain. test 97...

The results of the comparative-morphological analysis Typha astrakhanica are presented. It has been established that according to morphological signs, plants from southern reservoirs (Volga delta) Astrakhan oblast differ those given in botanical literature, T. angustifolia, australis, domingensis, grossheimii. described species membranous, rounded at apex upward-directed lobes (ears) vagina ste...

Golden trumpet, Tabebuia chrysotricha, is a native tree from the Brazilian Atlantic rain forest, with a broad latitudinal distribution. In this study, we investigated the potential effects of short-term changes in micro-weather conditions on structural features, and total protein and carbohydrate content of golden trumpet leaves, using structural and histochemical approaches. Leaves were harves...

Lejeunea pocsiana, a new species from Fiji, is described and illustrated. It characterized by its large size, robust stems, ventral merophyte 4-8 cells wide, broadly ovate to triangular-ovate leaves with rounded leaf apex, subquadrate almost flat lobules two distinctly differentiated teeth, bifid underleaves cordate slightly auriculate bases, smooth cuticle poorly developed trigones. A key that...

Leaves are packed in a bud in different ways, being flat, enrolled, or folded, but always filling the whole bud volume. This « filling law » has many consequences, in particular on the shape of growing folded leaves. This is shown here for different types of folding and packing. The folded volume is always part of an ellipsoid, with the veins on the outside rounded face, and the lamina margin o...

Strong latitudinal patterns in leaf form are well documented in floristic comparisons and palaeobotanical studies. However, there is little agreement about their functional significance; in fact, it is still unknown to what degree these patterns were generated by repeated evolutionary adaptation. We analysed leaf form in the woody angiosperm clade Viburnum (Adoxaceae) and document evolutionaril...

Since 1968, three spontaneous 4x melons (Cucumis melo L.) plants were discovered in our field or greenhouse plantings. Two were found in the cultivar Planters Jumbo and one in the virescent marker C879-52. Each of these 4x plants had rounded cotyledons, shorter internodes, thicker stems and leaves, more hairs, and smaller fruits, with larger stem and blossom scars, than their 2x counterparts. A...

Miliusa gokhalaei (Annonaceae), a new species from the Western Ghats, India, is described and illustrated. It is distinguished by unequal rounded leaf bases, sessile or shortly pedicellate flowers, thick fleshy petals, glabrous carpel, and included connective of anther. It is closely related to M. indica and M. eriocarpa, with which it shares sub-sessile or shortly petiolate, hairy-nerved leave...
