A Photographic Study

NOTE:
species heading in red unpublished because of no type sheet 

The first "whorl" of the flower structure in made up of 5 sepals at the end of the pedicel and just outside of the corolla. In the flowers development the calyx at first covers the whole flower bud. As the inner parts maturate, they expands and the corolla pushes ever larger, eventually for the most part hiding the small calyx. Most taxonomists consider this structure so minor that some do not even include it in a hoya description. It is, however unique in some species and has structural characteristics that should be observed and noted. It can vary in length, width, amount of overlap at the base of the sepals, its central thickening, the amount and placement of indumentum (hairs) on its outer surface, in edge ciliation. Occasionally with hair cells inside and in the presence or absence, and number length etc. of a tongue like structure at the sepal sinus area the "ligule"
In Latin this is a Third declension noun and its stem is "calyc-". we usually see it as "calyx" or the genitive form "calycis".

Hoya Literature Compendium (6)

I herein present as much of the hoya literature, pertaining to each individual species, as I had available to me. The volume's as originally constituted in hard copy consist of five Sections in Volume I, see the contents page, following for details.

Volumes II through VI followed. Here the species were listed in alphabetic order, followed by the volume (where applicable), the date in brackets; page number when available to me. The author’s name follows this; the species is presented in bold type. All other binomials within a given text are italicized. If the literature is in a language other than English I have translated it (with the exception of Chinese and Japanese Script and the Vietnamese publications in most cases). The word Translation has been underlined for easy reference. Comments and Notes are also underlined.

Literature here presented on disks in Word For Windows 95 format. By the use of "FIND" and "GO TO" all words are easily accessed. This is available under the Edit function.

The vast majority of pertinent Hoya literature is presented, however they’re some I do not have available. I would appreciate your sending me any corrections in the text or in the translations. I would also appreciate copies of any new Hoya literature (not popular presentations) or any older works that I have missed. They will be added to upgraded editions of this publication.

My work on this compendium will have been worthwhile and I will be pleased if this material helps those interested in the Genus Hoya; especially if students are able to further their studies by having in one place the major portion of pertinent Hoya literature.

I owe a lot to many people who have unselfishly helped me in compiling and translating. They are too numerous to mention here. I appreciate all their efforts and help in this regard.

Passport: Genus Eriostemma

Genus Eriostemma

 Translated from 135:
Section VII. Eriostemma Schlechter. I thought it best to present here this distinctive
section Eriostemma. This section is so well and sharply different, that one could consider
whether or not to regard it as a separate sub-genus. I have so far presented above briefly
the main points, but now I wish to present them once again in more detail. In habit there
is a strong similarity that can be found with EU-Hoya, but the branches are softer and
more fleshy and consistently with more or less soft hairs. The peduncles are
extraordinarily thick and soft textured, the calyx as with Pterostemma more strongly
structured, and the large hairy blooms are likewise fleshy. The gynostegium with the
corona scales stand upon a woolly matted column that is the outgrowth formed of the
filaments, which are united with the corona tube. The pollinia are distinguished (marked)
as opposed to the other Hoya species by means of the fact that the translators have
undergone a strong development and exhibit a twist; also the retinaculum is rather large.
The pollinia are more club shaped and moreover do not have the keel on the outer edge,
characteristic of other Hoya sections.

We for a long time now have been aware that the species in this section have very
little in common with the Genus Hoya and so have made the decision to place it into the
2 Genus status. In addition to the differences noted by Dr. Schlechter above, the characters of the Genus Eriostemma (Schlechter) Kloppenburg and Gilding are as follows:

Acknowledgments
As usual this work was not completed without the help and cooperation of a large number of friends. The most important contribution has been from those who over the years have sent me flowers for microscopic study. This has been a continuous flow of material. Among those who have filled the gaps in my collections are Ted Green and Edward Gilding of Hawaii. Ann Wayman of Oregon, Jerry Williams, Harriette Schapiro of California. Eva-Karin Wiberg and Torill Nyhuus of Sweden and David Kleijn of The Netherlands. I have also received flowers from Chanin Thorut, Thailand and many others. Another contribution has been Photos of foliage and of flower clusters, mainly supplied by Ann Wayman, Central Point, Oregon.

Over the years the personnel at the herbarium UC Berkeley, University of California have assisted me with access to herbarium sheets and literature. I must also add thanks to Dr. Domingo Madulid and the late Professor Juan Pancho of the Philippines for their help and guidance, as well as access to the respective herbaria. The list of assistance over the past 22 years is too long to enumerate here. Help has been supplied from many quarters and it has been accepted with much appreciation.
All those acknowledged in my work on “Hoya Pollinaria a Photographic Study” and in the book “The World of Hoyas a Pictorial Guide” are hereby thanked again as all this work is intertwined and overlapping.
