Torches have a bulbous spotted base that is blue, purple or gray. Males have a purple head and yellow anther, while females have a bright, yellow head and orange stigma. The fruits of a female torches are round and heavy, often pink or red in color.
Torches grow in the understory of terrestrial habitats, surrounded by thick vegetation and other autotrophs such as umbrella trees. However, torches need to grow in unshaded patches to obtain sufficient sunlight.
Torches are autotrophic, using radiation from the Allurian sun and atmospheric gases to produce complex organic compounds. These compounds are stored in its fleshly base. Stored energy eventually transfers to fruits, causing the base of the torch to shrink during reproduction.
Torches reproduce sexually. Males produce gametes that are carried to females by small pollinators. This pollination causes females to produce fleshy fruits containing many seeds. The seeds are dispersed by herbivores that consume the fruits.
Alien Zoo Biologists theorize that male and female torch plants differ in the color of their top leaves because only female torches produce fruit. Female torches need to attract herbivores in order for the seeds of their fruits to be dispersed. Natural selection has caused them to be yellow, as yellow coloration overall attracts the most species that will disperse their fruits in Alluria.
