Front view illustration of a Koa tree, endemic to the Hawaiian islands. There are actually two species of koa native to Hawaii. The large forest koa is well known around the world for the beautiful hard wood. Koa's smaller cousin, koai?a, that once grew in the lowlands of most of the main Hawaiian Islands, has an even harder wood that is much prized for its gnarled grain

Pickleweed is an invasive or introduced plant in Hawaii. It has succulent, brilliant green leaves and is common in salt marshes and tidal shorelines. It grows slowly in soils with high salt concentrations and areas with seawater overwash where it suffers little competition from other plants. The species manages salts by sequestering them in cell vacuoles and eventually shedding the leaves

Front view illustration of an Aweoweo, endemic to the Hawaiian islands. Native water and land birds (e.g., Nihoa finch), and seabirds use Aweoweo for food, nesting material or nesting sites. Early Hawaiians used the wood to form shark hooks (makau mano) fitted with bone points. Aweoweo leaves and shoots were wrapped in ti leaves, cooked and eaten in times of food scarcity by early Hawaiians

Front view illustration of a West Indian Lantana. It is a weed of cultivated land, fence lines, pastures, rangelands, and waste places. It thrives in dry and wet regions and often grows in valleys, mountain slopes, and coastal areas. It is somewhat shade-tolerant and, therefore, can become the dominant understory in open forests or in tropical tree crops. In pastures it forms dense thickets which shade out and encroach upon desirable pasture plants. With time it can form pure stands over large areas, the
