“…The amphistomatic and hypostomatic patterns of distribution of stomata observed in species of Solanum sect. Polytrichum , were previously reported for species of others sections of Solanum by Ahmad (1964), Araújo et al (2010), Granada‐Chacón and Benítez‐Rojas (2005), and Nurit‐Silva et al (2011), inter alia , being the amphistomatic type the most common in all studied species of Solanum . Acccording to Parkhust (1978), amphistomatic feature may represent a means of increasing the photosynthetic rate to allow efficient gas exchange compared with the hypostomatic type, which was observed only in Solanum asterophorum .…”

“…Despite being a common type of trichome observed in the studied species of Solanum sect. Polytrichum , similar trichomes are also recorded for species of other groups such as the section Crinitum (Araújo et al, 2010). The stellate‐glandular trichome only observed in Solanum sublentum is a characteristic type of species of Solanum sect.…”

“…The pattern of leaf epidermal cells observed in this work in species of Solanum sect. Polytrichum , which has anticlinal walls of epidermal cells adaxially curved and sinuous in abaxial, is a common type in the genus and already reported to other sections: Geminata (Benitez‐Rojas, 2007), Brevantherum (Benitez‐Rojas and Mesa, 1991), Acanthophora (Granada‐Chacón and Benitez‐Rojas, 2005), Crinitum (Nurit‐Silva et al, 2011; Araújo et al, 2010) and Torva (Nurit‐Silva et al, in press), inter alia . The morphology of anticlinal walls in Solanum is variable compared with the adaxial and abaxial surfaces, and the curved type is most frequent for the studied species of the genus.…”

“…The importance of microscopic features of leaf epidermis and its annexes, stomata and trichomes, have long been recognized by taxonomists, and has proved to be very relevant in some taxonomic groups, providing an additional tool not only for systematic studies (Stace, 1984). The epidermal characters of Solanum , especially trichomes, are recognized as a valuable tool for taxonomic studies of the genus contributing not only to the infrageneric and interspecific delimitations (Roe, 1972; Seithe, 1962, 1979), as well as herbal drug control (Araújo et al, 2010). Relatively few studies have focused on the leaf anatomy of Solanum species as a support to the taxonomy of the genus, especially for the big subgenus Leptostemonum with only two studies, being one for section Acanthophora (Granada‐Chacón and Benitez‐Rojas, 2005) and another for section Crinitum (Araújo et al, 2010).…”

The morphological similarities among the species of Solanum are remarkable, and are often very difficult one clear distinction between them. This paper presents a comparative anatomical study of the leaf epidermis of five Brazilian species of Solanum sect. Polytrichum, carried out using light and scanning electron microscopy. The leaf epidermis surfaces were investigated to evaluate their taxonomic significance to be used for separation and delimitation of the species of the section. As results, some micro-morphological characters of the leaf epidermis, such as density, distribution and type of stellate trichomes, and the anticlinal walls of epidermal cells, and also the type and distribution of stomata proved to be the most useful and distinctive characters for the separation and delimitation of the species, and also may contribute as an additional support to the interspecific taxonomy and systematic of Solanum sect. Polytrichum.

“…According to Martins and Appezzato-da-Glória (2006), correct histochemical characterization and identification ensure confidence in the use the plants for therapeutic purposes and in complimentary chemical studies.

Solanum aculeatissimum Jacq. is a shrub considered to have valuable medicinal potential in folk medicine in China and Nepal. The fruit extract is used for toothache, scabies, headache, dandruff and lice infestation. A limited number of reports address techniques of tissue culture for this plant. Therefore, the objective of the present study was to establish the species in vitro from seeds and subsequently to compare the production of primary and secondary metabolites in the plant's leaves in situ and in vitro and in calluses obtained from leaf segments. Seedlings were established from seeds in Murashige and Skoog (MS) medium with a 50% salt concentration.The seedlings were kept under a photoperiod of 16 h of photosynthetically active radiation at 45-55 µmol m -2 s -1 provided by fluorescent bulbs. The callus induction experiment followed a completely randomized design consisting of 2 doses of kinetin (KIN), 2.5 and 10 mg L -1 , in the absence or presence of light. Segments were inoculated in glass bottles containing 50% MS medium, 30 g L -1 of sucrose, 3.5 g L -1 of agar and 1 mg L -1 of 2,4-D (2,4-dichlorophenoxyacetic acid), with the pH adjusted to 5.7±0.03. We observed that in vitro cultivation of calluses resulted in greater secondary metabolite production and accumulation, regardless of KIN concentration. In calluses, the best alternative for potentiation occurred in cultivation in the absence of light when compared to the tissues of both in situ and in vitro leaves.

The medicinal plants are utilized globally considering the cheap and chemical free source, but their correct identification and authentication is prerequisite for safety and efficacy of plant-based medicines. The present study encompassed traded medicinal plants (16) with high therapeutic value from diverse families like Brassicaceae, Berberidaceae, Malvaceae, Salicaceae, Myrtaceae, Papilionaceae, Ascelpiadaceae, Colchicaceae, Violaceae, and Vitaceae for detailed microscopic study of characters that is, morphology, pollen shape and sizes, P/E ratio, pore length and width, spine length, colpi dimensions, and exine sculpture pattern. The plants showed noteworthy differences in microscopy of Wattakaka volubilis having pollinia, translator and corpusculum like structures while pores were visible in Colchicum luteum, Alcea rosea, and Hibiscus syriacus. The spines were observed in Centipeda minima, A. rosea, and H. syriacus being dimorphic spines in A. rosea and monomorphic in H. syriacus. The exine sculpturing pattern was reticulate in mostly studied plants however distinctive exine pattern was noted in Berberis aristata and Berberis lyceum. The highest polar diameter, equatorial diameter and exine thickness among studied plants were observed in H. syriacus (161 μm), C. luteum (50 μm) and Vitis jacquemontii (1.10), respectively. Thus, microscopy of medicinal plants in addition to other taxonomic evidence offers a supportive skill in authentication, consequently utilization by local consumers and pharmaceutical industries.
