SOUTH AFRICAN SPECIES OF 
aspect, frequently with numerous shortened axillary branches, often with 
imbricate leaves, including species which favour damp situations, but often 
distinctly xerophytic. Flowers subsessile or shortly pedicelled, very small, 
axillary, either solitary or in small tufts. Petals almost free. Ovaries in 
nos. 23 and 24 multi-ovulate, in the others 2-ovulate. 
A. Annuals. 
a. Calyx longer than petals. Petals ovate subacute minutely 
cuspidate. Leaves ovate or sublanceolate, obtuse or 
acute. Internodes fairly regular throughout the length 
of the stem. 
19. Cr. fUamentosa, Schonl. 
b. Calyx longer than petals. Petals lanceolate acuminate or 
hairpointed. Leaves much acuminate or hairpointed. 
Internodes usually very short, rarely as long or longer than 
the leaves and in that case the upper gradually shorter. 
20. Gr. campestris, Endl. 
c. Petals blunt, rounded at the apex. Leaves with rough 
margin. 
1. Sepals slightly longer than petals. 
23. Gr. bergioides, Harv. 
2. Sepals nearly 3 times the length of the petals. 
24. Gr. aristata, Schonl. 
B. Perennials 1 with woody stem at the base (frequently tuberous in 22). 
a. Leaves ovate lanceolate tapering to a blunt point. Branches 
slightly flexuous. Calyx shorter than petals. 
21. Gr. parvula, Harv. 
b. Leaves from an oval base lanceolate acute. Branches usually 
rigid. Calyx about the length of the petals.

VII. Lycopodioides group. Small xerophytic halfshrubs with closely 
set 4-ranked leaves with elongating branches and in addition often with 
numerous very short axillary branchlets. Flowers 5-merous, subsessile, very 
small, either solitary or in few flowered dense cymules in the axils of the 
upper leaves. Carpels with more than 2 ovules. 
25. Gr. lycopodioides, Lam. ( 
VIII. Umbellata group. Marsh- or landplants either with spathulate 
or distinctly petiolate flattish leaves, in some species arranged in a radical 
1 In the two perennial species here mentioned the plants flower at a very early stage, and thus 
they may appear to be annual. The specimens should therefore, in case of doubt, be compared 
with the detailed descriptions. Otherwise confusion may easily arise. I have, e.g., often seen 
young specimens of Cr. parvula growing in damp places in the shade which were almost 
indistinguishable from Cr. Jilamentosa, Schonl.
