100 THE FLORIST. 



cultivated land in the county of Southampton, and much exposed to 

 the south-west winds, this plant has literally been in flower for 

 months past ; whether as growing in the common garden soil, trained 

 on a trellis in front of the mansion, or in that part of a colonnade 

 with a considerable roof protection, or rambling at will over beds of 

 American plants, the effect produced has been of the most charming 

 and beautiful kind; the flowers, too, have been most useful in 

 bouquets and in the adornment of epergnes, vases, &c. ; the large 

 bright yellow flowers contrast admirably with Camellias, Hyacinths, 

 Primulas, and such like, and to these they add a peculiar grace 

 when the stems and flowers are allowed to protrude outwards. The 

 time is not distant, when not only every garden, but the sunny side 

 of every cottage in these kingdoms, will be enlivened and beautified, 

 during the dull months of winter, with the golden flowers of this 

 charming plant. D- B. 



FERN CLASSIFICATION.— No. V. 



We resume our sketch of the subdivision of the Poli/podinece, the first 

 group of which, having transverse sori, formed the subject of the pre- 

 ceding paper (p. 44). 



In the second group (2) in which the sori are parallel with the veins 

 and oblique to the midrib or costa, there are scarcely any cases suffi- 

 ciently anomalous to cause difficulty in the way of classification. 

 The sori, generally forming a line of some length — oblong simple linear, 

 or continuous in reticulated lines, here take the same course as the 

 veins ; whereas, in the former group, they were ranged across them, 

 and in that which follows, are normally punctiform or dot-like, one of 

 the dot-like clusters only occurring on one vein. It may, however, be 

 useful to mention, that although the sorus is here normally and really 

 oblique to the costa, in some cases the obliquity is so trifling that it 

 appears to be subparallel therewith ; but then it is to be observed that 

 it is not placed across the veins, but follows their course, so that there is 

 no real deviation from the characteristics of the group, and no real 

 difficulty in classifying the plants. The same feature, that namely of 

 the sori lying parallel with the veins, also serves to prevent misappre- 

 hension in the case of some of the much divided Aspleniece (which 

 form part of the group) where the segments are so narrow as to 

 contain only a single vein, with a sorus lying along it. 



This second group breaks into two lesser divisions ; of these the first 

 again separates into two sections in continuation of the series already 

 explained, and the remaining one breaks up into three other sections. 

 The divisions are these : — 

 Sori parallel with the veins, &c. — 



(a). Sori iudusiate — 



— lateral on the veins, the indusium attached by 



its base g 13. Aspleniece. 



— dorsal on the veins on an oblong cristseform 



receptacle, to which the indusium is attached 



by its centre §14. Didymochlceneae. 



(b). Sori naked or spuriously indusiate (dorsal) . . (see forward).
