Abstract Phylogenetic analyses of early-diverging Faboideae have indicated that genera previously positioned in distinct tribes are instead closely related, e.g. in the Amburaneae clade, and the relatively recent rearrangements of many genera into clades has hampered the identification of morphological synapomorphies for previously unrecognized clades. Our aims are to evaluate anatomical vegetative characters of leaflets attached to reproductive features in the Amburaneae clade, to identify new synapomorphies for the clade and subclades, to identify characters supporting intergeneric relationships and diagnostic characters for the genus and species and to provide information about the morphology and histochemistry of secretory structures. The study was based on the anatomy of the leaflet of 19 species of the Amburaneae clade. Papillae cells, the presence of vascular system units and hypodermis are shared features of Amburaneae. Anatomical characters of the leaflet can be diagnostic at the generic and specific levels in Amburaneae. Secretory structures found in the clade are secretory cavities, secretory channels, idioblasts, mucilaginous epidermal cells and glandular trichomes. The broader concept of Amburaneae is reinforced here by morphological and molecular data, with the identification of new synapomorphies. Our dataset supports the intergeneric relationships resolved by molecular data.

Superficial Portion

The blood supply to the nape-of-the-neck flap was studied in 11 18-week-old fetuses by infusion of methyl methacrolate into the vascular system. Dissection of the posterior cervical region showed that the major blood supply to this area was through perforating vessels from the superficial portion of the ramus decendens of the occipital artery and the posterior auricular artery. Since a “named artery” was not found in the longitudinal axis of the flap, as is reported in the literature, it should be considered a cutaneous rather than an arterial flap. The findings of this study are consistent with classical anatomical descriptions about blood supply to this region. Collateral vascular pathways from the occipital artery and the costicervical trunk are discussed.

Anatomical Study

An anatomical study was made of galls which occur naturally on the stems of boysenberry and Himalaya blackberry plants. The galls form at any region of the stem of the floral canes of plants systemically infected with Agrobacterium rubi and originate from or near the cambial layer, and not from the outer layer of the pericycle. The vascular system in galls caused by A. rubi and A. tumefaciens on broad bean, tomato, sugar beet, loganberry, and Himalaya blackberry plants is connected to the vascular system of the organ on which they are growing.

Rabbits have been used as an experimental model in many diseases and for the study of toxicology, pharmacology and surgery in many universities. However, some aspects of their macro anatomy need a more detailed description, especially the abdominal and pelvic arterial vascular system, which has a huge variability in distribution and trajectory. Thirty cadaveric adult New Zealand rabbits, 13 male and 17 female, with an average weight and rostrum-sacral length of 2.5 kg and 40cm, respectively, were used. The thoracic aorta was cannulated and the vascular system was filled with stained latex S-65. The celiac artery and its proximal branches were dissected and lengthened in order to evidence origin and proximal ramifications. The celiac artery emerged between the 12th and 13th thoracic vertebra in 11 (36.7%) rabbits; at the level of the 13th thoracic vertebra in 6 (20%) rabbits; between the 13th thoracic vertebra and the 1st lumbar vertebra in 12 (40%) rabbits; and at the level of the 1st lumbar vertebra in only one (3.3%) rabbit. The mean length of the celiac artery was 0.5cm. The celiac artery first branch was the lienal artery, the second branch was the left gastric artery and the hepatic artery arose from the left gastric artery in all the dissected rabbits. No relation was observed between the celiac artery length and the rostrum-sacral length in rabbits. The number of left gastric and lienal artery branches and the distribution of celiac artery origin are not gender dependent.

The process of in vitro rooting and the anatomical characters of in vitro and ex vitro leaves and roots of Prunus x davidopersica 'Piroska' were studied. Best rooting percentage (50%) and highest root number (5.0) was achieved in spring on a medium containing 0.1 mg/I NAA + 30 g/1 glucose. At the end of rooting the parenchyma of the in vitro leaves was more loose and spongy, than during the proliferation period. In the first newly developed leaf of an acclimatised plant, the parenchyma was much more developed, contained less row of cells and less air space too, compared to the leaves developed in the field. The in vitro developed root had a broad cortex and narrow vascular cylinder with less developed xylem elements, but at the end of the acclimatisation the vascular system became dominant in the root.

Based on floral vascular system, the authors analysed the problem of pseudomonomeria, and the inter-generic relationships within the Calloideae. The hermaphrodite flowers of Calla do not have a perianth. The superior, unilocular ovary is surrounded by 10 to 12 extrorse stamens. Most of these flowers have an ovary wall which receives three carpellary traces. These three traces divides again to produce 9–12 bundles. At the base of the ovules, an oval vascular plexus can be seen on which the traces of the ovules are inserted. It originates from three carpellary bundles, even though it is connected to certain staminal traces. The anatomical study showed that the syncarpous gynoecium of Calla is composed of three carpels that are joined edge to edge. The bitegmic, anatropous, apotropous ascending ovules are located on a basal placenta. The number of ovules varies from 4 to 10. The basal placentation of Calla is of the basal-axile type. It derives from an axile placentation which is similar to that found in Lysichitum. Among the Calloideae, it is with Orontium aquaticum that Calla palustris shares the greatest number of characters: superior ovary, unilocular, tricarpellate gynoecium, basal placentation, and a reticulate pollen. In Orontium, the existence of 6 tepals and 6 stamens was noted while in Calla, 10–12 stamens were observed. It is possible that 6 of the 12 stamens of Calla, correspond to the 6 tepals of Orontium. The subfamily Calloideae is a heterogeneous taxon at the level of floral morphology.

Multicellular green algae may be an ancestral form of the vascular plants. These algae exhibit cell wall structure, chlorophyll pigmentation, and physiological processes similar to those of higher plants. The presence of a vascular system which provides water, minerals, and nutrients to remote tissues in higher plants was believed unnecessary for the algae. Among the green algae, the Chaetophorales are complex highly branched forms that might require some means of nutrient transport. The Chaetophorales do possess apical meristematic groups of cells that have growth orientations suggestive of stem and root positions. Branches of Chaetophora incressata were examined by the scanning electron microscope (SEM) for ultrastructural evidence of pro-vascular transport.
