Tcones Orchidearum Austro-A fricanarum extra-tropicarum ; or Figures of extra- 
tropical South African Orchids. By Harry Botus, F.L.S. Vol. 1, part 
2, tt. 51—100. London: William Wesley & Son, 28, Essex Street, 
Strand. 
A noice of the first part of this valuable work appeared at page 270 of our 
first volume, and now we are able to welcome the second, which has just 
made its appearance. It contains a series of fifty partly-coloured plates, from 
drawings by the author, illustrating a selection of the Orchids of South 
Africa, many of which are very remarkable in structure. The figures 
comprise eleven species of Disa, eight each of Satyrium and Disperis, four 
of Habenaria and Pterygodium, three of Angrzcum, Mystacidium, and 
Platanthera, two of Brachycorythis, and a single example of Eulophia, 
Pachites, Schizodium, and Zeuxine. The last-named, Zeuxine cochlearis, 
Schlechter (t. 58), is very interesting, being allied to Z. sulcata, Lindl., from 
India and China, and the genus new to South Africa. Eulophia 
calanthoides, Schlechter (t. 51), it may be noted, is drawn from a specimen 
which flowered at Kew in June, 1893, but has been identified with wild dried 
specimens. The handsomest species figured, probably, is Disa purpurascens, 
Bolus (t. 86), one of the blue Disas which it was hoped some time ago would 
prove amenable to cultivation, though the one introduced seems to have 
again been lost sight of. Disa sanguinea, Sander (t. 80), has deep crimson 
flowers, which are rather small, and arranged in a short, dense, cylindrical 
spike. Schizodi tennife » Schlechter (t. 88) is a very remarkable 
species in which the petals and lip are extended into dark purple spreading 
tails, giving the flower a remarkable insect-like appearance. This genus, it 
may be noted, was suppressed in the former part of the work, but is now again 
revived, while a somewhat similar remark applies also to Mystacidium. 
Brachycorythis ovata, Lindl. (t. 62), has purple, “delightfully fragrant 
violent-scented flowers,” which are arranged in a dense cylindrical spike, 
and would be worth introduci ig to cultivati Satyrium sphzrocarpum, 
Lindl. (t. 75), and S. longicauda, Lindl. (t. 70) are already known in gardens. 
Disa aconitoides, Sander (t. 79) is well named, as the resemblance to 2 
dwarf Aconite in the scape, as well as in the shape and colour of the flowers, 
is striking. The flowers are lilac, with a few darker spots. 
A very curious purple-flowered Disperis is figured under the name of D. 
stenoplectron, Rchb.f. ? (t. 90), with the following significant remarks :—“ It 
is impossible to know certainly whether this is Reichenbach’s plant. The 
description of a species of so complicated a structure by the use of few words 
is difficult, if not impossible; and that by the author of this plant is far too 
brief. In such a case the student ordinarily refers to the type specimen ;
