These flowers can be fertilised in eighteen distinct ways, necessitating a vast number of experiments, the result being, as in the case of the cowslip, that flowers fertilised by the pollen from stamens of the same length as the styles, gave on the average a larger number of capsules and a very much larger number of seeds than in any other case.
Cattleya dowiana aurea, from Reichenbachia Series I Volume I Plate 5.. Reichenbachia: Orchids Illustrated and Described is a four-volume 19th-century text created by German-born orchidologist Frederick Sander which features life-size illustrations and descriptions of nearly two hundred orchids with text in English, French, and German.
A Phalaenopsis flower. Orchids are easily distinguished from other plants, as they share some very evident derived characteristics or synapomorphies.Among these are: bilateral symmetry of the flower (zygomorphism), many resupinate flowers, a nearly always highly modified petal (labellum), fused stamens and carpels, and extremely small seeds.
Another common orchid is putty root (Aplectrum hyemale). Putty root is a larger orchid with a flower stalk that can reach between 1- and 2-feet tall and puts out anywhere from eight to 20 flowers.
The orchid family is one of the largest flowering plant families in the world. Orchids can be found on every continent except Antarctica, from the steamy jungles of Asia to the dry deserts of ...
Cut the spike two or three nodes below the lowest flower, and the orchid may bloom again in as soon as 8 to 12 weeks. “There’s a 50% chance a new stalk will grow from the old one,” Kondrat says.
It is similar to other orchids in the Dactylorhiza maculata group. D. maculata ssp. maculata is distinguished by having the lip less deeply trilobed, while D. maculata subsp. saccifera has one spur large and saccular (sac-shaped) and the bracts of the inflorescence as long as or longer than the flowers.
The flowers are monandrous in the subfamilies Vanilloideae, Orchidoideae, and Epidendroideae. Like many others before him, Dressler believed that the monandrous orchids form a monophyletic group. It is now known that monandry arose twice in the orchids, once in Vanilloideae, and again in the common ancestor of
