FIGURE 4 in Floral similarity and vegetative divergence in a new species of Bletia (Orchidaceae) from Mexico
FIGURE 4. Phylogenetic relationships in Bletia inferred by maximum parsimony (MP) and maximum likelihood (ML) analyses of ITS DNA sequences. A. One of the six shortest trees found by the MP analysis; an asterisk (*) indicates that the clade collapses in the strict consensus. B. ML tree. On both trees branch lengths are drawn proportional to the number of character changes; numbers associated to branches are bootstrap percentages.

FIGURE 3. Comparison of some floral attributes of Bletia mixtecana and B. parkinsonii (in all instances, placed on the left and right, respectively). A−B. Base of labellum; note in A the central channel formed by the thickened veins that turn into keels further up towards the apex. C−D. Midlobe of labellum. E. Column; note the prominent, yellow auricles on the ventral margins of B. parkinsonii (right). F. Ventral view of column apex. G. Dorsal view of column apex. H. Ventral view of column apex after dislodging the anther to show the pollinia. I−J. Pollinaria. Photographer: Gerardo A. Salazar.
