| Bromeliads, aroids, and orchids all have numerous species which live in the tops of tropical trees. |
|
| Monocots comprise one-quarter of all flowering plant species, most of these are orchids, grasses, sedges, palms, and aroids. |
|
| Along with the magnificent orchids are aroids, a family including dieffenbachias, philodendrons and other popular indoor plants. |
|
| As with the number of floral parts, this character is not always reliable, as there are many monocots with reticulate venation, notably the aroids and Dioscoreales. |
|
| Volunteer guides roam the greenhouses ready to answer questions about rooms filled with rain forest tropical plants, blooming orchids, aroids and gesneriads. |
|
| Heat generated by other aroids is thought to volatilize odorants that attract pollinators. |
|
| In most monoecious aroids, female flowers senesce before male flowers mature, making cross-pollination necessary. |
|
| Aroids include philodendrons, anthuriums, aglaonemas, caladiums, spathiphyllums and dieffenbachias. |
|
| Aroids are perennial herbs characterized by inflorescences consisting of a finger-like spadix surrounded by a vase-like spathe. |
|
| The majority of aroids are climbers and epiphytes of tropical rainforests. |
