to those incorporated in the walls of Perichaena depressa and 

 P. corticalis. The deposits are- either continuous over the whole 

 surface of the sporangium-wall, or are divided into patches 

 separated by spaces from granules. 



Hemitrichia minor, n. sp. Plasmodium? Sporangia scat- 

 tered, stalked or sessile, globose, 0-2 to 0*4 mm. diam., pale 

 yellowish-buff, somewhat glossy; sporangium-wall membranous, 

 pale yellow, minutely papillose or marked with delicate close-set 

 curved lines of thickening, and having scanty superficial deposits 

 of refuse matter. Stalk black, cylindrical, 0-1 to 0-2 mm. high, 

 enclosing dark refuse-matter ; in one case, two sporangia are 

 mounted on a common stalk. Capillitium consisting of a loose 

 network of flaccid yellow threads, 2-5 to 4 /x diam., with few or 

 many often swollen free ends, and marked with three or four faint 

 spiral bands ; the threads not infrequently show bulbous expan- 

 sions, and are either almost smooth, or studded with slender 

 spines 1 to 4 /* long. Spores pale yellow, closely and minutely 

 warted, 9 to 10 /a diam. 



This minute species has been gathered on three occasions by 

 Mr. Kumagusu Minakata, in the province of Kii, Japan, amongst 

 moss on the bark of fallen branches. More material is needed 

 before the position of Hemitrichia minor can be satisfactorily 

 ascertained. It appears to be allied to H. Karstenii (Eost.) Lister, 

 as suggested by Mr. Minakata ; it differs in the sporangia being 

 globose and often stalked, in the more delicate sporangium-walls, 

 and in the more or less spinose capillitium. The last character 

 varies in the different gatherings; in one specimen, which is 

 perhaps not perfectly developed, the capillitium threads are 

 almost smooth ; in another they are marked with close-set warts 

 and short spines, while in the third specimen the threads are 

 studded with both short and long spines. 



DOUBLE DAFFODILS.* 

 By Helen Saundees. 



In the month of March in this year (1910) I bought a bunch 

 of common daffodils or Lent-lilies, gathered in Chittlehampton 

 parish, among which I found one that was double, but not of the 

 ordinary form of Telemoniits plenus, for it had none of the trumpet 

 or tube-like shape but was nearly flat ; the calyx or five outer 

 segments of the perianth being of a pale yellow or primrose 

 colour, the next row a deeper shade, but not so dark as the ordi- 

 nary daffodil, and so on to the centre. I made inquiries respect- 

 ing its habitat, and visited the locality with the person who had 



Keprinted from the Transactions of the Devonshire Association for the 

 Advancement of Science, Literature, and Art, 1910, xlii. pp. 423, 424.
