Tilney and Van Wyk (1997) report protrusions of intine,
and is distinguished from the intine in containing more pectin and less
Clypeate grains are either functionally omniaperturate and have a thin exine and uniformly thickened intine
(Thanikaimoni, 1986; Furness & Rudall, 1999, 2000) or are porate with localized thickenings of intine
(Chanda & Ghosh, 1976; Halbritter & Hesse, 1995).
Exine (Ex) and Intine
(In) are formed in this stage (fig 2 E) and tapetum in this plant is plasmodial type.

All conifer pollen is dehydrated on its release into air, but all swell in varying degrees on contact with water as result of hydration of the cellulosic intine.
In Clade IV all families show the same response, in which pollen sinks, the intine expands considerably, and the exine is shed (Southworth, 1988).
Si tenga presente, intine
, che agli studenti e stato chiarito esplicitamente che il lavoro non sarebbe stato sottoposto a verifica formale, (6) ne avrebbe influito sul voto finale del corso.
The exine has a very thin endexine layer, and a fibrilar intine
with numerous invaginations coated by the plasmalemma can be observed.
Pollen grains possessing a much-reduced exine and elaborated intine
(omniaperturate and/or exineless) are known to occur in 54 families of angiosperms and are nearly ubiquitous in Zingiberales (Kress, 1986).
The bonuses played were; INTINeS, COERCES, and INHALER and the game was finally won by the Pakistan's Sulaiman 469-392, which makes him the 3rd MISO Champion.
