LIBRARY BOOKS Please return Library Books at the November Meeting for stock-taking 95 How it is done Reg Shooter The October meeting could be called Sarcochilus night, out of a total of 31 plants benched 17 were Sarcochilus, providing a sight to behold. They ranged from the tiny cream spotted red flowers of Sarcochilus Weinhart, exhibited by Brendan Killen (It is a cross between Sarco weinthalii & hartmannii) on a small plant to the large specimen sized plant of Wally’s Sarco hartmannii it carried a total of 104 racemes (Bodo counted them) with an average of 18 crystalline white flowers per raceme. The judges were very impressed with the culture of this species they examined it closely eventually awarding the owner with a Certificate of Cultural Commendation. Another Sarcochilus that caught the judges eye was a relatively small plant of Sarcochilus falcatus grown by Steve Howard. It was mounted on a piece of tree branch, which seems to be the way this orchid prefers to grow and carried two 150mm long racemes of almost pure white large flowers 30mm across. This is about as big as they get on this species. Sarco. falcatus is the most widely spread of the Sarcochilus genus. In its natural habitat it extends from North Queensland right down the eastern seaboard to Eastern Victoria. It is a very variable species some have flowers that remain ‘cuppy’ and do not open fully whilst others have wide flat segments. Like many of the Sarcochilus species it is lightly perfumed smelling a little like tuberoses. In the terrestrials there was a magnificent specimen pot of Caladenia tentaculata a species endemic to South Australia. It was exhibited by Les Nesbitt who gave an interesting account of how he grows this species. There were eighteen 35cm tall flowers in a 300mm pot with many seedlings around the base of the plants. Les informed the meeting that he had ‘potted on’ this pot starting with a 150mm pot 3 years ago then into a larger pot until this size.
