A LETTER FROM HEINRICH BEYRLE IN GERMANY

Dear Roy,

Sadly I read in the last NOSSA Journal of the death of Jack

Warcup.

Enclosed please find a photograph of a recently flowered

hybrid: Calochilus robertsonii x Thelymitra nuda. I made this

cross in 1993, germinated seeds in 1995 and it flowered in

March 1998. As these hybrids do not appear to occur in the wild

and artificial hybrids between Calochilus and Thelymitra are not

previously recorded as flowering, the hybrid is of some

scientific interest!

I expected the flowers to be similar to Calochilus imberbis but

with the colours of green, yellow, blue and red it is much

prettier. I intend to register it at Kew as Calomitra 'Memoria

Jack Warcup'.

(Many people will remember Heinrich when he worked here In

Adelaide at Waite under the guidance of Jack. Eds)

RHIZANTHELLA

The underground orchid has now been reported from Yorke Peninsula which means it has been supposedly seen

over a 500km area of South Australia.

SPRING SHOW

Yes its only a few weeks to our Spring Show at St Peters Town Hall! We will need trading table plants. Please fill

out the volunteer book at the next meeting. We need ticket sellers, PR persons, trading table experts tea makers

and lots of exhibitors!

Television and orchids

On a recent Burkes Backyard the terrestrial Pterostylis concinna was shown.

On September 18th Gardening Australia with Mike Harrison contained a segment on Native Orchids

SPECIAL RAFFLE:

a copy of the much prized 1911 edition of South Australian Orchids, by R.S. Rogers is to be raffled over the next

2 months. Tickets will be on sale at meetings and the Show.

JULY SPEAKERS

We had a fascinating demonstration on deflasking. Firstly Kevin Western showed slides of well developed

terrestrials in flask, plants with large tubers, plants actually flowering in flask, and even discussed the possibility

of a self pollinated species setting seed and that seed germinating in the flask to complete the cycle!

Kev showed how a jet of water is used to wash off the agar.

Les Nesbitt and George Nieuwenhoven completed the show by demonstrating how to deflask both terrestrials and

epiphytes.

AUSTRALIAN DENBROBIUMS No 28 by Sandy Philips

Dockrillia schoenina

This species was named by Lindley in

1846 (as Dendrobium schoeninum)

from plants grown at Kew.

The name honours the 19th Century

botanist and naturalist Schoenin.

Found growing on rocks or trees from

Newcastle north to Mackay. It forms

large tangled clumps which are

suberect or hang downwards depending

on light intensity. Flowers are few and

usually single, although there may be 2

or 3 sometimes. Leaves are pencil-like

or grooved and often develop black

markings. The flowers are white as for

the genus, about 3cm across and with

green or purplish markings.

Relatively common on Sheoaks along

creeks and rivers. Previously also

known as Dendrobium beckleri F.

Muell. This easily grown species is

grown cool in Adelaide on wood or

even outside on fruit trees.

NOTES ON THE COLOUR PLATES in ORCHIDS OF SOUTH AUSTRALIA

(continued)

Plate 87 Corybas fordhamii has to be one of the most difficult orchids to find, (perhaps only exceeded by the

underground orchid). It hides under tussocks of grass in deep bogs and would probably never have been found if

cattle had not eaten out the swamp thickets which hid them. The same cattle will probably cause the extinction of

the species in SA.

Plate 88 Corybas incurvus comes in many forms, from translucent green to cherry red, hispid or not. These dark

coloured specimens were growing in Wirrabara Forest in the Flinders Ranges.

Plate 89 This plant of Corybas unguiculatus was photographed in the Mylor Parklands. Note that the column can

be seen through the transparent flower base.

Plates 90-91 Cryptostylis subulata the moose orchid also photographed at Mylor (in the Adelaide Hills) the

boyhood home of the author. In the 1950's over 100 orchid species could be found within walking distance of the

town.

Plate 92 Cyrtostylis reniformis a real close up of the flower by Paul Reece, this shot clearly shows the rounded

labellum apex typical of this species.

Plate 93 From close-up to whole plant, the flowers of Cyrtostylis robusta may look similar to those of the

previous species but if you look closely at the flowers you can see the pointed tip on the labellum on these much

larger C. robusta flowers

NATIVE ORCHID SURVEY AT UPPER STURT SCHOOL 1996-7 Thelma Bridle

NOSSA conducted a survey of this area in the early 1980's. In 1996 the school requested assistance to update this

information so that it could be included in their application for Heritage Listing of the school grounds.

Different species of orchid can be found in flower here at most times of

the year so we were pleased to be invited to a winter visit in 1997.

This co-incided with a barbecue and working bee in which a bush-care

group were assisting parents and students in removal of exotic

shrubs. Epacris impressa in cerise, pink and white were flowering in

profusion at this time and many fungi were recorded. We were able

to identify orchids for those present and point out some we hadn't seen

before . The visit added 4 species not on the orchid list. As there were a

couple of species we wished to positively identify with flowers I returned

in August but added nothing new. A final visit in December confirmed

Dipodium roseum , the saprophytic hyacinth orchid in flower.

Over a ten year period there were few changes in the orchid populations

although in different years the different weather conditions affected the flowering of most species. Populations of

most species seem viable as seed is set most years and numbers are static or growing. All species have been

identified from flowering plants.
