Abstract

This study describes the comprehensive micromorphology and taxonomic evidence of 28 species of Annonaceae from Nigeria and the Cameroons using light microscopy to provide additional anatomical and morphological diagnostic characters to complement the systematics boundaries of the infrafamilial and tribal clades. The epidermal cell shape varies from polygonal to irregular on both or either surface except Annona reticulata with isodiametric on the adaxial surface. The anticlinal wall patterns are either undulated, straight, or curved in the family. The constant generic feature encountered includes hypostomata which are mostly paracytic except in Cananga odorata, Isolona zenkeriUvaria angolensis and Letestudoxa bella possessing pericytic, 1 + 2 laterocytic and stephanocytic, respectively. Hemiparacytics, brachyamphiparacytic and brachyparacytic stomata, which are variables of paracytic are also present. These stomata complexes proved useful in species delimitation and diagnostic of the family Annonaceae. Other foliar epidermal features were crystals of different shapes and sizes mainly of druses and styloid, unicellular trichome type, and anticlinal wall pattern. The pattern of affinity among the species suggested evidence of similarity and differences in the micromorphological characters, which cumulated to the distinct identification of each species. Based on the most reliable characters within the family, the k-means cluster, distance matrix, correlation coefficient, and UPGMA dendrogram tree were constructed.

Abstract:

The foliar epidermal characteristics of all West African species of the tribe Parietarieae and some taxa in the tribe Urticeae were investigated by the means of light microscopy for the purposes of easy identification and justification of recent taxonomic merging of Fleurya with Laportea.

In the tribes, cell number is higher on the adaxial surface (52 to 110) than on the abaxial surface (19 to 96), stomata number varies from 31 to 42 per mm² while cell size ranged from 60.8 – 70.4 µm x 22.4 – 32.0 µm on the adaxial surface and 32.0 – 40.0 µm x 16.0 – 22.4 µm on the abaxial surface.

Generally, all the species have hypostomatic leaves and anomocytic stomatal type but paracytic and anisocytic types are diagnostic for Laportea aestuans, Laportea ovalifolia, Parietaria laxiflora, and Laportea alatipes.

Glandular and simple trichomes of different sizes were observed in all the taxa except in Girardinia heterophylla and L. ovalifolia.

The cell shape, anticlinal wall pattern, and stomatal type which correlate to a reasonable extent have supported the amalgamation of Laportea and Fleurya.

Crystal sands of calcium oxalate were found in L. ovalifolia, Girardinia condensata, and Parietaria laxiflora while peltate scales distinguished P. laxiflora from other species. The species have medicinal and economic values. An artificial indented dichotomous taxonomic key for separating the taxa is presented.

Abstract

A comparative foliar epidermal and petiole anatomical morphology of six commonly used pharmacodynamic species of Senna in Nigeria was investigated with a view to elucidating their taxonomic significance and present complementary data which would aid the recognition of the species.
The cell shape may be polygonal and irregular on both surfaces and either polygonal or irregular on any of the two surfaces of the leaf. Anticlinal wall is either straight or undulate and curved. Usually, the epidermal cell size is more on the adaxial surface and the leaf is either amphistomatic or hypostomatic.
Trichomes are usually slender acicular to conical and glandular or non-glandular. The vascular system of the petiole is arranged in a spaced arc.
Based on this an indented dichotomous key is presented to distinguish the species.

Abstract

Comparative foliar epidermal characteristics of 15 species of Acalypha L. in West Africa are analysed using both light and scanning electron microscopy.

Presence of hypostomatic leaves supports the series accepted by Bentham and Hooker (ser. Pantogynae-Acrogynae and ser. Pantogynae- Pleurogynae) except A. wilkesiana. In taxa of other series amphistomatic leaves were recorded.

Among other taxonomically useful features of the genus are polygonal and irregular epidermal cell shapes, curved and undulate anticlinal walls, presence of regular to irregular striae and deposition of waxy flakes on the leaf surfaces.

A. ceraceopunctata and A. segetalis can be distinguished from other species by the presence of peltate scale and only paracytic stomata respectively.

An artificial bracketed dichotomous key is presented to delimit species of the genus Acalypha.

Abstract:

Two complimentary studies of anatomy and phytochemistry used in pharmacognostic drug research have been conducted on Musanga cercropiodes using light microscopy and phytochemical methods.

Diagnostic anatomical features of the plant include bulbous trichome bases, and flaky strand-like waxes. Other distinguishing features of the plant are hypostomatic leaf, anomocytic stomata, abaxially restricted simple unicellular and non glandular trichomes as well as crescentiform and hairy petiole.

The bioactive compounds which are present in both leaf and bark are alkaloids, flavonoids, tannins, free and bound anthraquinone, saponin and cardiac glycosides but anthocyanosides and cyanogenic glycosides are absent.

Musanga cercropioides is a popular plant in folkloric medication in West Africa.

Abstract

Epidermal morphology has been used to delimit the species of Momordica (L.) (Cucurbitaceae).

The anticlinal wall pattern may be undulate, straight or curved while the epidermal cell shape is either polygonal or irregular.

The leaf is hypostomatic and stomatal type is usually anomocytic. Stomata index value ranges from 2.38% to 13.1%, while mean epidermal cell number on the abaxial surface is usually not less than 50.

Other features that show variations are stomatal and epidermal cell size.

Based on these features, the medicinal species M. balsamina Linn. and M. charantia Linn. and a commercial species M. angustisepala Harms are distinguished.

An artificial key has been prepared to identify the species even when the leaves are in fragments.

Abstract:

The genus possesses a suite of leaf epidermal characteristics which reflect the affinities among the species. The most generic constant features are anomocytic stomatal type and undulate anticlinal wall pattern on the abaxial surface.

Whereas the species distinguishing features include paracytic stomata which were recorded only in L. breviflora, hypostomatic leaf distinguishes L. abyssinica and L. rufa from other species that are amphistomatic, uniform epidermal cell shape on both surfaces of the leaf differentiates L. guineensis and L. siceraria from other species that have dissimilar patterns on the surfaces.

Other features are possession of globular head trichome in L. siceraria, imperfect conical trichome in L. abyssinica and bicellular glandular conical trichome in L. sphaerica.

Quantitatively, epidermal cells number generally varies from 28/mm² in L. vulgaris to 112/mm² in L. breviflora on the adaxial and abaxial surfaces respectively while stomatal number varies from 2-20/mm² and stomatal index is between 2.2 – 34.9 % on the adaxial surface and 8.2 – 20.8 % on the abaxial surface.

Based on these features, two main groups and subgroups are proposed based on neighbour joining cluster derived from Euclidean similarity measure. Also, an indented dichotomous key is presented for species delimitation.
