further from the shore where the 

 bottom fell steeply, the var. typica 

 was growing in about 6 — 8 feet of 

 water with only about 3 rows of 

 somewhat longer ramuli. Fig. 109 

 shows one of the forms of var. 

 typica we meet here; compare also 

 Weber-van Bosse, Monographie, 

 pi. XXVII, fig. 1 and especially 

 pi. XXVIII, fig. 1. 



If we now go to the more 

 sheltered localities and first con- 

 sider those, where the water is 

 still clear, we fmd here specimens 

 whose erect shoots are about 6-12 

 cms high, more or less richly ra- 

 mified and with rather spread 

 branches (see Figs. 110 and 111). 

 These bear commonly 3 rows of 

 ramuli, seldom more; often espe- 

 cially in the upper part of the 

 branches however we find only two 

 rows. The ramuli are ovate to oval- 

 cylindrical or quite cylindrical with 

 a short spine at the apex; they 

 are commonly about twice as long 

 as the breadth of the midrib and 

 in the distichous branches often 

 opposite. The forms we meet with 

 here are of the var. typica and com- 

 monly agree with the figures 2 and 

 3 in Plate XXVII in M^i^WEBfiR's 

 Monograph and with Reinke's 

 figure 42, 1. c. If we pass further 

 into the lagoon where the water 

 is often muddy and the light there- 

 fore less, the forms become gra- 

 dually larger up to 20 cm high 

 sometimes even higher and moreover 



more flabby, generally they are also less ramified. The branches are 

 somewhat spread out having the ramuli placed sometimes in 3 some- 

 times in 2 rows. They are cylindrical somewhat bent upwards, 3 — 4
