| Labellar papillae show greater diversity, and may be conical, obpyriform, villiform, fusiform or clavate. |
| The retiform pattern consists of elongated, slitlike branching tubules containing intraluminal papillae lined by flattened to cuboidal cells. |
| The critical process depends upon whether the ectoderm can contact a condensate of specialized mesenchyme called the dermal papillae. |
| This paper reports the presence of bacteria on the surface of filiform and fungiform papillae of rats using scanning electron microscopy. |
| As the style grows and the papillae develop, adherent pollen grains are observed with increasing frequency. |
| Anthers are introrse and fused longitudinally through many papillae, in such a way that they form a cuff around the ovary. |
