Observe the leaves of the Rhynchostylis gigantea. They have a deep-green hue and a length of up to 12 inches. They are about 3 inches wide and have a notch at the end.
Take note of the time of year. In the northern hemisphere, the Rhynchostylis gigantea begins to flower in January and continues flowering for about four months. If you are looking at an orchid that resembles the Rhynchostylis gigantea but is not flowering during this time, you may need to double-check.
Memorize the attributes of the flowers. The Rhynchostylis gigantea's flowers are purple and white. Some albino forms are a burgundy hue. The blooms are about 1/2 to 3/4 inch wide and are arranged on a cascading stem called a spray. On the spray, you will see about 30 or more small blooms.
Take a deep breath. If you smell citrus, then you probably are looking at a Rhynchostylis gigantea orchid.
