(2) The first species of each germs is given its full generic and specific 
names, with authority. For second and following species the genus name 
is expressed by its initial letter. 
(3) A limited number of synonyms are given in italics within brackets 
next to the accepted names. They are also shown in the Alphabetical 
List in italics. Only such synonyms have been inserted as seem neces- 
sary to save confusion and facilitate study ; as, for instance, where two 
collectors record the same plant under different names, and where changes 
of nomenclature have taken place since the publication of the earlier 
South African Floras. 
(4) A considerable number of additional synonyms have been neces- 
sitated in order to keep the Kecoed uniform with Torre & Harms' 
Genera Siphonogainanun . In no instance does this imply any expres- 
sion of opinion on my part as to which is the more correct classification. 
The following example will show how a synonym of this kind appears. 
Tlie genus Chailletia is included by Torre & Harms under the genus 
Dichaioctalitm. Therefore, " Chailletia cymosa, Hook.,'" is recorded thus : — 
4283 — Dichapetalum cymosum (Hook.), Torre & Harms. 
{Chailletia cymosa, Hook.), 
and is indexed under both names. 
(5) Following the binomial, and synonyms if any, on a new line 
references are given to any works where descriptions of the species may 
be found. These references are not necessarily, or even generally, to 
original descriptions, but to such publications as are likely to be 
accessible to South African students. 
(6) Finally, under each species are recorded such details as are known 
of its collection, in the following order : Locality, altitude, month of col- 
lection, collector's name, aad herbarium number. Note. — A locality is 
named once only in each record, e.g. " Matopos, Nov. Marloth, 3588 ; 
Eogers, 5185." This means that Dr. Marloth's No. 3588 was taken in 
the Matopo Hills in November, and Archdeacon Eogers' 5185 was also 
taken in the Matopos, date unknown. 
The names of between forty and fifty collectors appear in the Eecord. 
Many of these put themselves to great trouble to make and send me 
duplicate copies of their lists of identified plants. The records of others 
I have obtained from various publications. The following is a list of 
the names that are most frequent in the Eecord, together with the 
abbreviated forms used : — 
Eand.— Dr. E. F. Eand, F.L.S., formerly of Ehodesia. 
Allen. — Mr. C. B. F. xVUen, formerly in charge of Forests for E'lodes'an 
Government. 
Gates.— The late Frank Gates, F.E.G.S.
