Spadix (botany) Typically, the stigmas are no longer receptive when pollen is released which prevents self-fertilization. We also have Compound Spadix Inflorescence in which the axis is branched. Usually whole Inflorescence is covered by a stiff boat shaped path for example- Coconut. Spadix (botany) In botany, a spadix ( ; plural spadices , ) is a type of spike inflorescence having small flowers borne on a fleshy stem.

Enteric coating However, as the solvents for such solutions are organic solvents, there's a concern about the toxicity potential of the traces of the residual solvents in the tablet coating. The first form of gastro-resistant coating was introduced by Unna in 1884 in the form of keratin-coated pills, although it was later discovered that they weren't able to withstand gastric digestion. Salol was also used by Ceppi as one of the first forms of enteric coating. However, the first material that was extensively used as enteric coating agent was shellac, since its introduction in 1930. Properly treated or hydrolyzed shellac showed different
