An apex alone weighed about 2 μg dry weight but, due to the difficulty of precise dissection, dry weights of apex plus leaf and stem base tissue ranged at the extreme from 2 to 25 μg. However, as the floral apex enlarges and undergoes perianth initiation, the cells in the abaxial region of the bract enlarge and become more vacuolated than those of the floral apex or adaxial portion of the bract (Fig. Flowers are inconspicuous, tubular structure and attached to the showy heart-shaped bracts. It uses the formal upright design, but you'll remove all the branches until the main foliage at the top. Instead of leaves, various floral appendages arise from the node.
