Figs 38-45. Fig. 38. Oblique view from removed bract showing differential enlargement of stamen 
primordia on a single flowered unit that follows the pattern of initiation (numbered). The median 
furrow (mf) has begun on the first initiated stamen primordium. Fig. 39. Polar view of floral 
meristem (M) after stamen initiation. Fig. 40. Side view of enlarging floral meristem/early carpel 
(arrow) with one stamen primordium removed illustrating the growth on the side of the largest 
stamen primordium. Fig. 41. Later stage of enlarging floral meristem/carpel primordium. 
Fig. 42. Side view of carpel primordium, the cleft beginning to form (arrow). Fig. 43. Polar view 
of carpel primordium with cleft (arrow). Fig. 44. Oblique side view of carpel primordium, all 
stamens and tepals removed. Fig. 45. Oblique view of incomplete valvate tepal aestivation; only 
two tepal tips converge and come into contact over the other floral organs. The other two tepals 
fit Into the comers formed by the contacting tepals. Scale bars; 38-44 = 50 pm; 45 = 100 pm.
