ADDITIONS AND CORRECTIONS TO THE RECORDED 

 FLORA OF THE TRANSVAAL AND SWAZILAND. 



II. 



By Joseph Burtt-Davy, F.L.S., F.R.G.S. 

 (Read, July lo, 1918.) 



The first list of additions to the recorded flora of the Trans- 

 vaal and Swaziland appeared about five years ago,* including 

 additions up to June 30th, 1912. Since that date additional parts 

 of the Flora Capensis have appeared, which include a large 

 number of new species, and revisions of families and genera ; 

 addition to the flora have also been recorded in other publica- 

 tions. I have not attempted to bring these together here, but 

 have prepared a short account of ten species which do not appear 

 to have been elsewhere recorded for the Transvaal. 



I am indebted to the Curator and staff of the Bolus Herbar- 

 ium, and to Mr. Frank Bolus, for the identifications ; specimens 

 are deposited in the Bolus Herbarium, Capetown, and the 

 herbarium of the School of Mines and Technology, Johannes- 

 burg. 



1. Cymbopogon dregeanus (Nees) Staff (Andropogon 

 dregeamts Nees,; Fl. Cap., y'li.). — Near Breyten Station, Ermelo 

 District, alt. 5,886 ft., March 22. 1917, on the railway embank- 

 ment, Burtt-Davy 17491. There is only a small patch of this 

 rank-growing Tambookie grass, which is obviously adventive 

 there, probably introduced by means of goods or cattle traffic 

 from Natal or Swaziland by way of Piet Retief. The Flora 

 Capensis localities for this species are: The Transkei (i,ooc- 

 2,000 ft.), and Natal (the coast and Estcourt). It seems strange 

 that such a typically Low- Veld grass should be able to establish 

 itself at such a high altitude and in such a bleak district, but it 

 is in a spot apparently somewhat sheltered from the cold south 

 and south-east winds, and facing north, where it probably catches 

 the early morning sun, and the warm air-currents rising fron"/ 

 the valley below. In the vicinity. Paspalum dilatatum, a grass 

 sensitive to frost, grows freely, and keeps green in winter, at 

 about 6,000 ft. alt., on a hill slope having a similar aspect. 



2. Agrostis natalensis Staff. — Ermelo, alt. cir. 5,689 ft., 

 March 22, 191 7, in a pan near the coal-mine, associated with 

 Pennisetitm sphacelatum Dur and Schinz, Burtt-Davy 17466B. 

 The only locality given by Staff is LTmpumlo, Natal, 2,000 ft. 



3. Cragrostis c.'esia Staff'. — Ermelo, alt. cir. 5,689 ft., 

 March 22, 191 7. in a pan near the coal-mine, associated with 

 Arundinella Ecklenis Nees. and distinctly characteristic, Burtt- 

 Davy 17468. This is clearly a High-Veld species, being recorded 

 from the Cathcart Division, Cape Province, and from Natal, at 

 altitudes ranging from 4.000 to 5,000 ft. 



*Rept. S.A.A.A.S. (1912) Port Elizabeth 343-356.
