180 MR. H. BOLUS'8 CONTRIBUTIONS TO 
tract of country 197 square miles in extent, 102 species of 
Orchidez, all terrestrial, have been recorded *. 
The paucity of Orchids in the excessively arid Karroo Region 
is not surprising. Of the three species recorded, Habenaria are- 
naria extends also to the South-Eastern Region ; while Holothrix 
parviflora and Corycium bicuspidatum are, so far as is yet known, 
confined to the Karroo Region. On the mountains near Graaff 
Reinet at 4600 feet, Holothrix villosa has indeed been found ; 
and on the Kaus Mountains of Namaqualand, Satyrium erectum, 
Disperis purpurata, and Pterygodium Volucris (besides a Holo- 
thrix undetermined). But these stations, though situate in or 
near the Karroo Region, are rather, by reason of their altitude 
and different climate, outliers from the neighbouring Regions ; 
and it would be misleading to regard them as belonging to the 
Karroo. 
The species are arranged in each genus, and in each section of 
a genus (where the genera are so divided), in the chronological 
order of their publication. 
A note of interrogation placed before the number signifies 
doubt as to the existence of the species within our limits. A 
similar note placed after the number and before the name, signifies 
doubt as to the location of a species in the section of a genus 
where it is placed. 
The terms Western, South-Western, South, and South-Eastern 
districts signify those districts of the Cape Colony proper, and 
refer chiefly to the coast country within 100 miles (and for the 
most part within 50 miles) of the sea.
