irregularly dotted about ; the number of these spots varies con- 

 siderably in the different leaves, 



26b. .4. Greatheadii, Schonl. (Rec. Alb. Mus. I, p. 121).— This 

 species is closely allied to A. Dauniii, Engl. et. Gilg. (H. Baum, 

 Kuneni-Sambesi Expedition, Berlin 1903, p. 191, fig. 90). My 

 desci'iption wa« drawn up from wild specimens when gathered, 

 In growing it in the Museum grounds I find that the leaves are 

 variable in shape, sometimes ovate, the spots on the upper surface 

 are sometimes rusty white, the bracts exceed the pedicels in length, 

 the tube of the perianth is a little over f its total length. 



A. grandidentata, Salm-Dyck, A. Davyana^ Schonl., A. 

 Greatheadii, Schonl., and A. Baiintii, Engl, et Gilg form a series 

 which are linked together to such an extent that they may well be 

 looked upon as species " im werden begriffen," and it will be 

 interesting to study them further in their native homes. 



27 (315). A. Greeiiii, Bak. — It seems to be very doubtful 

 whether this species occurs in Natal as stated on p. 39. It is not 

 known to Mr. J. M. Wood. I have grown it for years, and it was 

 therefore, a great surprise to me when I found that this year 

 the plants which I described only last year as a new species under 

 the name of A. hamangivatensis, (Rec. Albany Mus. I., 

 p. 122), have lost almost all distinctive ■ characters, and 

 must undoubtedly be referred to A. Greenii, which, there- 

 fore, occurs near Palapye road station on the upper reaches 

 of the Limpopo River. I saw hundreds, if not thousands, 

 of specimens, but none had leaves more than c.20 cm. (about 8 in.) 

 long, while Baker states that they are 15-18 in. long. In my 

 garden they reach 22 in., and the leaves of the plants from Dr. 

 MacOwan and those brought from Khama's country are now 

 practically indistinguishable. The differences in the flowers have 

 also practically vanished, those on the plants from Khama's 

 country being a little brighter in colour and a trifle larger, but 

 they are growing in better soil, which may account for even these 

 differences. 



27a. A. Dyeri, Schonl. n. sp. — Stem short, simple. Leaves 

 about 15, rosulate, gracefully recurved, up to 52 cm. long, about 

 9 cm. broad and 6 mm. thick at the base, lanceolate, tapering
