Two basic types of tapetum have amoeboidal (periplasmoidal) type so that its periplasmoidal extensions are observed toward the anther locule. The microspores at releasing time are vacuolated and they have peripheral nucleus.
intybus the tapetum passes at the first a parietal (secretory) phase with multiplication of the nuclei (2-3 nuclei per cell) and later it changes in to amoeboidal (periplasmodial) type so that its periplasmodial extensions are observed toward the anther locule (Fig.
For the percentage of the empty locule fruit characteristic, the mean value of the progenies was 15% (Table 2).
Flowers leathery and greenish-white; buds (7) 9-12 mm long; bracteoles 4-6 mm long, (4) 5-7 mm wide, suborbicular, appressed to the calyx; sepals (4) 5-7 mm long, (5) 6-8 mm wide, orbicular to suborbicular; petals (8) 9-14 mm long, (5) 7-8 mm wide, free, oblong; stamens 42-48, 9-12 mm long; filaments free, linear; anthers sagittate with yellow pollen; ovary 6-8 (9) mm tall, pyriform, 5-locular with 16-20 ovules per locule; style 3-4 mm long, cylindrical; stigma capitate and somewhat 5-radiate.
The seeds were separated from others within a locule using a gentle stream of air.
Orbicules are readily observable by scanning electron microscopy (SEM) in mature anthers as a layer of tiny particles lining the inner locule wall, in close contact with the pollen grains (El-Ghazaly, 1999; Huysmans et al., 2000; Galati, 2003).
Flowers cream-colored; buds 8-9 mm long; bracteoles sepaloid, 4-5 mm long, 56 mm wide with membranaceous margins and appressed to the calyx; sepals suborbicular to orbicular, 5-6 mm long, 6-7 mm wide; stamens 45-50, 7-9 mm long with the inner whorl shorter than the outer whorl; filaments free and flattened; anthers sagittae with bright yellow pollen; ovary conical and striste, 4-5 mm tall, 6-loculed with 18-26 ovules per locule; style 3 mm long; stigma capitate and slightly 6-lobed.
Sections through the retrorectal tissue revealed a multilocular cyst with thin walls and smooth cyst lining, with the exception of one locule that measured 4.0 x 3.5 x 2.5 cm and was filled with glistening gelatinous content.
Several features common in Apiineae are also found in most of these groups, such as ovary-roof nectaries (Erbar & Leins, 2010), a single functional ovule (either per locule or per ovary), drupaceous fruits, and sheathing petiole bases, but there are significant exceptions to each.
Cranmeria trilocularis Reid and Chandler (1933; Chandler, 1961b), known only from the Sheppey locality, is a three-loculed berry, 17.5-18.5 mm, with 12-15 rows of seeds per locule attached to an axile placenta.
The surgical specimen consisted of a thin-walled, multilocular cyst with a dominant locule that measured 30 x 25 x 10 cm and weighed 3975 g (Figure 2).
