is still our opinion that orchids need feeding naturally through the roots in 
part at least, and that probably the best results come from ringing the changes 
with different manures. 
82. Hybridising continued as and when the desired pairs of parents 
could be obtained in bloom together. In all 214 pollinations were made result¬ 
ing in 142 successful crosses. Acknowledgment is made of gifts of pods from 
Mr. H. K. Kuok of Johore Bahru; Mr. Killop of New Guinea; Mr. E. de 
Saram of Ceylon; Mr. M. Lewis and Mr. A. J. Braga of Singapore and Mr. 
W. B. Muir of Australia. Their seed and seed from our own crosses were 
sown in the laboratory. 
83. The flask culture using coconut milk with Vacin’s formula on an 
agar base was continued, but in the latter part of the year small quantities of 
banana mash were added with most encouraging results. Addition of other 
fruit pulps is now under investigation. The general results have been so good 
as to be embarrassing to the staff of the seedling houses who have been hard 
put to handle the enlarged number of young seedlings coming forward for 
potting out. 
84. The following orchid hybrids which flowered in 1957 were later 
named in 1958: 
984, Arachnoglottis Brown Bars (Arachnis Maggie Oei x Tricho glottis fasciata). 
1472, Arandanthe Starnoa (Aranda Gold Starx Vandanthe Ellen Noa). 
977, Arandanthe Chas. dc Alwis (Arachnis Ishbelx Vandanthe Ellen Noa). 
Charles de Alwis, a Ceylon Burgher, was artist on the Gardens staff 
at the close of the last century and the beginning of this. 
1319, Arandanthe Grandeur ( Arachnis flos-aeris x Vandanthe Ellen Noa). 
1597, Dendrobium Paleface (D. Lim Chong MinxD. pl.alaenopsis var. Maunea 
Kea). 
1451, Dendrobium Concham (D. Constance x D. Champagne). 
1093, Aranthera Dainty ( Arachnis hookeriana var. luteola x Renanthera 
monachicd). 
1256, Aranda Marnie B. ( Arachnis hookeriana x Vanda Saphir). A cross made 
by Mr. A. J. Braga of Singapore and raised in the Botanic Gardens. 
920. Vanda Hogil (V. Kapohoxv. Gilbert Triboulet). 
First flowerings in 1958 which were also named were: 
2489, Spathoglottis Premier (S. Primrose var. Golden Flash x S. Dr. Yeoh). 
2398, Spathoglottis Golden Fleece (S. Primrose var. Golden Flash x S. aurea). 
857, Holttumara cochineal (Aranda Galistan var. Suntan x Renanthera 
coccinea). This is the second trigeneric hybrid to be flowered in the 
Gardens. Generic name is in honour of Dr. R. E. Holttum, Director, 
1925-1949, who initiated this work of orchid hybridising. 
1723, Dendrobium Murray Henderson (D. Neo-hawaii x D. Champagne). 
Named in honour of Mr. M. R. Henderson, Director 1949-1954. This 
hybrid has long arching sprays of peach coloured flowers. 
1890, Dendrobium Harlequin (D. Tanglin x D. Taurinum). An attractive hybrid 
with white sepals and violet lip and petals. 
2223, Vandanthe Candlelight (Vanda Cobber Cain x Euanthe sanderiana). A 
cross made by Mr. M. Lewis of Singapore and raised in the Botanic 
Gardens. 
Our own crossing of crosses made previously elsewhere which reached flower¬ 
ing in 1958 were: 1716 D. Louisae; 1125 D. Helen Adams; 2031 D. Liliha; 
2056 D. Anita; 1888 D. Bali, and 2001 D. Syaj. Cross 2031 was made using 
D. Pauline x D. Phalcenopsis var. schraederianum. There is a big variation in 
the siblings, but the best are free flowering with long-lasting long sprays of 
dark coloured flowers.
