Diplycosia rigidifolia sp. nov. from Mount Kinabalu, Borneo, Sabah, Malaysia, is described and illustrated. This species is similar to D. urceolata, but differs by its shorter petiole, thicker, strictly elliptic leaf blades, longer pedicels, calyx lobes with sharply acuminate apex, and larger purplish black fruiting calyx. The species is known only from Mt Kinabalu in northern Sabah state, Malaysia. 相似文献

A new species, Aspalathus crewiana is described and illustrated. It is closely similar to A. lenticula in the strongly rostrate keel petals and thorny leaflets, but differs in the subulate, spine‐tipped bracts, bracteoles and calyx lobes, presence of a pseudo‐peduncle and larger flowers. The new species, like A. lenticula, is placed in the Terminales group of A. subgenus Aspalathus. It is known from only two localities in the Western Cape where it was collected in Swartland Granite Renosterveld. 相似文献

A new species, Tropaeolum sparrei Ståhl (Tropaeolaceae), is described from submontane cloud forest habitat in western Ecuador. It differs from T. papillosum Hughes (the species it resembles most) by having thinner, tomentose stems, smaller, glabrous or subglabrous leaves with the petiole inserted relatively closer to the lower leaf margin, and flowers with uniformly coloured and straight calyx spurs. In leaf shape it is also similar to T. repandum Heilborn, from which it differs in its larger flowers with entirely black petals and blue anthers. 相似文献

A table with similarities and differences between both species is provided. 相似文献

A new species of Gentianella, G. tumailica sp. nov., from Tumail in the Kargil district of Ladakh, northwest Himalaya, India is described and illustrated. This novelity is morphologically similar to the sympatric G. stoliczka in inflorescence pattern, calyx and corolla shapes, sagitate anthers, more or less rounded seeds, but differs in smaller size of vegetative and floral structures, larger basal leaves, few cauline leaves, leaf apex obtuse to rounded, calyx lobes unequal (2 longer, 3 shorter), inflorescence enveloped by 4 foliaceous bracts, capsule elliptic to oblong and seed coat smooth. In addition, a diagnostic key to all Indian species of Gentianella is presented. 相似文献

Daphne thanguensis sp. nov. from north Sikkim of eastern Himalaya is described and illustrated. It is a narrow endemic related to D. tangutica Maxim. Daphne thanguensis grows in open alpine pastures and differs from D. tangutica by having leaves with revolute margin and a tuft of hairs at apex, ebracteate inflorescence and flowers, calyx lobes with a tuft of hairs at apex and annular, slightly undulate hypogynal disk. The new taxon is also close to D. retusa Hemsl. But can easily be differentiated by its sessile inflorescence, ebracteate flowers and tuft of hairs at leaf apices and calyx lobe apices. A conservation status of the new species in accordance with the IUCN red list categories and criteria is provided and discussed. 相似文献

The anthocyanin pigmentation patterns of stem, epicalyx, calyx, fading corolla, colour of anthers and petal spot character were studied in Hibiscus sabdariffa L.The stem and epicalyx pigmentation are controlled by the c and r genes. The two genes C and R are involved so far as calyx pigmentation, fading corolla colour and the anther and spot colours are concerned but an additional factor f is assumed to explain the segregation of the calyx pigmentation and fading corolla colour. Thus, a total of three genes (c, r. f) is distinguished, segregating independently.The intermedius type resembles the green-light-red rype of altissima in stem and epicalyx pigmentation but shows distinct differences in calyx pigmentation and fading corolla colour. 相似文献

Limonium cedrorum Domina & Ramondo, a new species belonging to the L. palmare aggr., is described and illustrated from the inland near Becharre (Lebanon). Its relationships with morphologically close taxa are discussed. Limonium cedrorum differs from L. sieberi and L. postii mainly by looser inflorescences and larger flowers. It differs from L. galilaeum by longer outer bract and longer scale below the first inflorescence branch, few sterile branches, thicker base of the inflorescence and denser spikes, and from L. graecum by the shape of the inflorescence, longer basal internodes and the shape of the calyx. 相似文献

Hess, R. T., Poinar, Jr., G. O., Etzel, L., Merritt, C. C. 1980. Calyx particle morphology of Bathyplectes anurus and B. curculionis (Hymenoptera: Ichneumonidae). (Department of Entomological Sciences, University of California, Barkeley, California, U.S.A.) — Acta zool. (Stockh.) 61(2): 111–116. The calyx regions of the ichneumonid wasps Bathyplectes anurus and B. curculionis were observed with the electron microscope to contain ovoid membrane-bound particles, 300 nm long by 250 nm wide. These particles were produced in nuclei associated with fibrous strands from which they appeared to bud. Particles apparently moved into the cytoplasm and budded into the calyx lumen, thereby acquiring the host's plasma membrane. The similarities and differences of these particles to the calyx particles of other wasps is discussed. 相似文献

Calyces of 306 species representing 181 out of the 236 genera of Lamiaceae have been studied with particular emphasis on the
amount of fibres and similar xylem cells. A characteristic calyx tissue called ``mesophyll fibres', reported by earlier authors,
is found to belong to the xylem. Most species of the subfamilies Lamioideae and Scutellarioideae differ from most other labiates,
and particularly from Nepetoideae, in having much larger amounts of fibres and similar xylem cells in the calyx tube. This
result supports cladistic hypotheses based on cpDNA showing that Lamioideae and Scutellarioideae are closely related and remotely
related to Nepetoideae. The new data also contribute to the knowledge about the phylogeny within Lamioideae. The amount of
fibres and similar cells also seems to be positively correlated with calyx size, calyx width, a ballistic dispersal mechanism
in Scutellaria, and the aridity of the habitat. Possible adaptive significances of these correlations are discussed. 相似文献

Lindernia kinmenensis Y. S. Liang, C. H. Chen, & C. L. Tasi sp. nov. from Kinmen (Taiwan) is described. The new species belongs to section Torenioides and is most similar to L. crustacea. It differs from the latter by the following characters: calyx pubescent between the ridges (vs pubescent on ridges), with (2)3(4) bristles on the ridge near the apex of the calyx‐lobes (vs without such bristles), corolla shorter, 6–8 mm long (vs 7–11 mm long) and pale purple (vs purple or blue), posterior theca with obtuse (vs acute) apex. This species is usually found in sandy wetlands. A line drawing, colour photos and SEM micrographs of pollen and seed as aids for identification are provided. 相似文献
