| Annona | genus | A plant genus of the family ANNONACEAE. It has edible fruit and seeds which contain acetogenins and benzoquinazoline and other alkaloids.[MeSH] | Annonaceae | The custard-apple plant family of the order Magnoliales, subclass Magnoliidae, class Magnoliopsida. Some members provide large pulpy fruits and commercial timber. Leaves and wood are often fragrant. Leaves are simple, with smooth margins, and alternately arranged in two rows along the stems.[MeSH] |
| Helianthus | genus | A genus herbs of the Asteraceae family. The SEEDS yield oil and are used as food and animal feed; the roots of Helianthus tuberosum (Jerusalem artichoke) are edible.[MeSH] | Asteraceae | A large plant family of the order Asterales, subclass Asteridae, class Magnoliopsida. The family is also known as Compositae. Flower petals are joined near the base and stamens alternate with the corolla lobes. The common name of daisy refers to several genera of this family including Aster; CHRYSANTHEMUM; RUDBECKIA; TANACETUM.[MeSH] |
| Annona squamosa | species | [no description available] | Annonaceae | The custard-apple plant family of the order Magnoliales, subclass Magnoliidae, class Magnoliopsida. Some members provide large pulpy fruits and commercial timber. Leaves and wood are often fragrant. Leaves are simple, with smooth margins, and alternately arranged in two rows along the stems.[MeSH] |
