EXPLANATION OF THE PLATES. 
Puate XIV. 
R. ferruginosus, Link. 
Fig. 1. Vertical section of old culm, showing the thick epidermal cells and 
two of the funnel-like cavities resulting from the breaking down of the 
resin-containing cells. The epidermal cells overlie a thick spongy layer 
of cellular tissue, &c. (see p. 222). 
Fig. 2. Transverse section of old culm, showing the same tissues as in fig. 1. 
Fig. 3. Vertical section of young culm to show the epidermal cells, and the 
cellular layer beneath. i 
Fig. 4. Transverse section of cortical tissues from culm rather older than in 
fig. 3. The subepidermal cells still retain their chlorophyll, but are 
beginning to assume the lengthened form and spongy texture character- 
istic of the old culm, 
(All the figures magnified to about 200 diameters.) 
Prate XV. 
R. Harveii, Mast. (see p. 253). 
Fig. 1. Plant, nat. size. 
Fig. 2. Spikelet, magnified. 
Fig. 3. Bract. 
Fig. 4. Unexpanded flower. 
Fig. 5. Outer lateral glume (conduplicate), anterior glume, and one of the 
inner glumes. 
Fig. 6. Ovary and staminodia. 
Fig. 7. Culm-sheath.
