181 
19 Restionacee”: Very probably connection is to be found in the 
Glumiflors. 
20 Centrolepidacee”: Closely related to the Eriocaulaces and to the 
Restionacess. It resembles the former family in Juncella with its capitate 
flowers, while it approaches the latter in Gaimardia with its di-merous 
flowers. 
21 Mayacacee”: That a close relation exists between the Mayacaces 
and Hydrocharitaceze can not be denied, if the agreement of the two families 
in their axillary flowers, in the perianth, and in the parietal placenta is to 
be regarded as a matter of importance. 
22 Xyridaceze: The relation of this to other families is as yet un- 
known to us. 
23 Eriocaulacee”: Related to the Restionaces, Centrolepidaces, Maya- 
caceze and Xyridaces through. the structure of the gyneceum and stamens. 
24 Thurniaceze: As above. 
25 Rapateacee”: This family undoubtedly is closely related to the 
Xyridacez, Eriocaulacese and other families; but differs from all of them in 
having atropous ovules. 
26 Bromeliacese®: These are certainly related to the several families of 
the Favinosee, such as the Commelinacer, Rapateaces, Mayacacess and Fla- 
gellariacese, in their general characters. But in other respects, they are closely 
connected with the Liliacese and Amaryllidaceze of the Liliiflore. When we 
take the family’s heterochlamydeous character into account, its place is near 
the Scitamineze, and the Liliiflore. In the position of the ovary on the 
other hand, some of the Bromeliacese are related to the Orchidaces, to the 
Hydrocharitacese and to the Scitaminacez. 
27 Commelinacee: As above 
28 Pontederiacee”: This family is somewhat related to the Liliaces 
in floral structure.
