of India, and are easy to cultivate. Polystachya pubescens and P. bracteosa 
are two African species worthy of mention. The former has deep yellow 
flowers, remaining in excellent condition for over two months, and the 
latter has curious depressed pseudobulbs and branched racemes of greenish 
flowers. Disperus secunda and capensis, belonging to the South African 
Flora, are both very remarkable in structure. 
Several other interesting species are in flower or bud, and will doubtless 
afford mattter for future notes. 
ODONTO. 
LAELIO-CATTLEYA x ELEGANS & L.-C. x SCHILLERIANA. 
THESE two very variable but quite distinct natural hybrids are still much 
confused in cultivation, though in some collections their differences are now 
correctly understood. Several incorrectly named plants have recently come 
under my notice, and the following note is penned with the hope of reducing 
the amount of confusion between them. 
There are three well known and handsome species of Orchids which 
grow together in the Santa Catherina district, in South Brazil, namely 
Lelia purpurata, Cattleya intermedia and C. Leopoldi, which evidently 
intercross very readily, for all the three possible combinations between them 
are known, as follows :— 
1. Lelia purpurata xX Cattleya intermedia (or the reverse cross) yields — 
Lelio-cattleya X Schilleriana. 
2. Lelia purpurata X Cattleya Leopoldi (or the reverse cross) yields 
Lzlio-cattleya X elegans. 
3. Cattleya intermedia X C. Leopoldi (or the reverse cross) yields 
Cattleya X intricata. 
Lzlio-cattleya X Schilleriana is often known in gardens as L.-c. X 
elegans alba or white elegans, but, as just pointed out, it is a quite distinct 
hybrid and should receive its proper name. The sepals and petals are 
generally white or blush because both the parent species have this character. 
Lzlia-cattleya x elegans is properly limited to what is sometimes 
called the Turneri section to distinguish it from those mentioned in the 
preceding group. The darker colour and generally broader petals are due 
to similar characters in the C. Leopoldi parent. 
Both the preceding hybrids are very variable, and have received 
numerous names, which points have already been treated in detail in this 
work (vol. i, pp. 235-238). 
Cattleya X imtricata is less common than either of the preceding 
hybrids, and is nearly intermediate between C. intermedia and C. Leopoldi, 
generally approaching the former in having rather narrow petals, and the 
latter in being spotted, a character which extends also to the sepals.
