A developmental classification system for the comparison of Puya raimondii giant Andean rosettes

Two datasets containing measurements of Puya raimondii plants, used as the basis of a developmental classification system for these giant Andean rosettes: "All data" contains data for all measured plants, while "Equal N data" contain a subset of the whole dataset used in statistical comparisons. "Microhabitat data" contain estimates of variables used to characterize different sampling locations.

Fig. 7 in Identification of anthocyanin and other flavonoids from the green-blue petals of Puya alpestris (Bromeliaceae) and a clarification of their coloration mechanism

Fig. 7. In vitro reconstruction of the petal color using the purified anthocyanin (preternatin C5, 1), flavonol (myricetin 3,3′,5′-tri-O-glucoside, 2), and flavone (luteolin 4′-O-glucoside, 4). The absorption spectra of the mixture of 1 and 2 (1:0, 1:1 and 1:3, A–C), and 1 and 4 (1:0, 1:1 and 1:3, E–G) were measured after being dissolved in three McIlvaine buffers (pH 5.6, 6.2 and 6.8). (D and H) Photographs of the mixed solutions shown in B and F, respectively.

A) Cross-section of the tip (the upper side is the adaxial layer); B) enlarged view of epidermal cells of (A); C) cross-section of the base (the upper side is the adaxial layer); D) epidermal cells in the center part. Length of bar = 100 μm (A, C, and D) and 20 μm (B).
