| Differential Staining with Orcein, Giemsa, CMA, and DAPI for comparative chromosome study of 12 species of Australian Drosera. |
| The organisms stained faintly with Giemsa and were negative by Grocott methenamine silver, periodic acid-Schiff, and mucicarmine stains. |
| On histologic examination, granules exhibited a typical, although faint, metachromasia with toluidine blue and Giemsa stains. |
| Organisms are large, usually located in a perinuclear or subnuclear, intraepithelial location, and stain positively with Giemsa, PAS, and methenamine silver stains. |
| Giemsa and toluidine stains revealed metachromatic granules in neoplastic cells. |
| Cytoplasm was abundant and intensely basophilic with Giemsa stain. |
