FIGURE 1 in Atlas of leaf surface micromorphology in Aloe L. (Asphodelaceae) from the Horn of Africa region

FIGURE 1. Leaf surfaces of Aloe taxa from the Horn of Africa presenting no infraspecific variation in the data from this study. For subspecies listed here, no variation within this infraspecific delineation was detected. Two images per taxon at magnifications with 100 µm and 20 µm scale bars, respectively, are given. When the stoma shown at the higher magnification is located in the lower magnification image, a black line connects the two for ease of comparison. Longitudinal axes of the leaves are oriented ± vertically. a. A. ankoberensis. b. A. calidophila. c. A. camperi. d. A. gilbertii subsp. gilbertii. e. A. gilbertii subsp. megalacanthoides. f.

FIGURE 2. Leaf surfaces of Aloe taxa from the Horn of Africa that exhibit infraspecific variation in the data in this study. Two images per taxon at magnifications with 100 µm and 20 µm scale bars, respectively, are given. Longitudinal axes of the leaves are oriented + vertically. a. A. debrana. b. A. elegans. c. A. jucunda. d. A. pirottae. e. A. pubescens. f. A. secundiflora subsp. secundiflora. The different images for A. debrana, A. pirottae, and A. pubescens (b, d & e) exemplify how cuticular waxes can be lost during preparation for SEM, and how specimens with and without waxes differ in the characters they reveal.

FIGURE 3. Intraspecific variation in A. lateritia and A. wollastonii. Each letter represents a different individual, and the individuals in blue boxes are most similar to previously published data for the species (Grace et al. 2009). Images were taken at a magnification of 300× or 1000× for the images of stomata. Individuals are arranged to illustrate expression as spectra of variation within the morpho-types observed. Differences in wax preservation can also be observed in both species. In A. lateritia, morpho-type I is represented by 4/7 of the individuals in our data and Morpho-type II by 3/7 individuals. Morpho-type I is primarily categorized based on the presence of singular central papillae of the periclinal walls. Specimen a exhibits the mildest expression, b, c, and d are individuals that can be considered intermediate in their expression, and e is the individual that most strongly expresses this character. Within this morpho-type anticlinal walls present as single-raised ridges. The singular central papillae of the periclinal walls of Morpho-type I are not seen in Morpho-type II, which also differs in that the anticlinal walls present as single and/or double-raised ridges. The variation included here clarifies that considering a wide circumscription for the species A. lateritia.
