Dendrobiums: Roy Tokunaga
Cindy Coty
12 pages, 31 photos

74-3 Peru River

Roy Tokunaga, of Waimanalo Hawaii, is a noted grower, hybridizer extraordinaire and partner with Harry Akagi in the well respected orchid business, H&R Nurseries. H&R Nurseries produces hybrids and seed-grown species for the hobbyist and commercial sales markets. Roy speaks all over the world at orchid symposia and societies about growing and hybridizing in the very large genus Dendrobium, a genus which he has been working with for over 30 years. Several months ago it was my pleasure to hear his talk on dendrobiums, and the following article is my effort to share some of his wisdom...

Some Lesser Known Dendrobiums of Section Latouria
Phil Spence
11 pages, 24 photos

In this article, I would like to discuss some of the rarer species of Dendrobium that belong to the section Latouria. This section, established by Blume in 1850, was originally the genus Latouria. Blume named the genus after a French botanist, Louis Theodore Leschenaultia de la Tour (1773 − 1826). The first species to be described was Latourea spectabilis, which today is known as Dendrobium spectabil. In 1855, it was reclassified as Dendrobium section Latouria by Miquel...

Orchid Digest 74-2i

This article is an introduction to a group of orchids that I find very satisfying and is written from a popular, not scientific point of view. I will share my experience growing dendrobiums from the Pedilonum section and also mention a few species from the closely related sections Calyptrochilus and Calcarifera. Although the debate continues as to whether or not these should be one section, or two or three sections, for this article I am keeping them as three distinct but closely related sections of the genus Dendrobium. Some intersectional hybrids have been made and the results are very promising...

Dendrobiums of China - A Checklist
Holger Perner
14 pages, 54 photos

The Genus Dendrobium was established by the Swedish botanist Olof Swartz in 1799. The scientific term “Dendrobium” roughly translates as “tree dweller,” referring to the habitat of these plants. In general, it is usually trees, but for many Dendrobium species in China it is rocks and cliffs, especially those important in traditional Chinese medicine called Shihu, which means “Rock Wort.” The new English edition of the Flora of China recognizes 78 species in 14 sections for China (Zhu et al., 2009), which is just a small fraction of the approximately 1100 species known for the entire genus. Fourteen species are considered to be endemic to China. Taxonomically the new edition of Flora is not necessarily the last word, but I have followed it here for the most part, though some taxa might perhaps better be relegated into synonymy of others...
