sion occurred in the calkins of an apparently healthy plant of Salix 

 caprea, growing on the banks of the Cam, near Audley End, Essex. 



" The catkins were of a light green colour, longer, and tapering to a point, instead 

 of being blunt, as is usual in S. caprea. In one case three apparently proceeded from 

 the same bud. The nectary and scale were very little altered, and the change is very 

 various in its character, and several intermediate forms occur in addition to those which 

 I am about to mention. Those enumerated are, however, the most remarkable. I 

 may here mention, that I do not mean that all the forms are to be found in the same 

 catkin, and also that the greatest alteration is observable in the flowers at the apex and 

 base of the catkins. 



" 1. Styles two, each bearing at the top two small pale stigmas; in other respects 

 as usual. 



"2. Scale and nectary as usual. Stalk of the ovarium extremely lengthened, re- 

 sembling a filament, downy, especially towards the base, terminating in an ovarium. 

 Style cloven, the cleft penetrating the substance of the ovarium ; at the base of the clo- 

 ven style, on one face only, appeared two yellow bodies like the lobes of an anther. 



" 3. Stalk greatly lengthened. Ovarium silky, not much altered at the base ; stig- 

 mas almost entirely obliterated ; instead of them a vertical depression or sinus, on each 

 side of which was a yellow antheriform body, erumpent from the substance of the ova- 

 rium. These contained perfect pollen, and in the lower ovarium-like portion I remarked 

 several ovules. 



" 4. Stalk forked or branched near the top, each fork bearing a silky body resem- 

 bling an ovarium. 



"5. Stalk forked; one fork filament-like, and tipped with an anther yielding pol- 

 len ; the other silky, approaching an ovarium in form, and containing ovules. 



" 6. In this form, in which the nearest approach to a stamen was made, each fork 

 bearing an anther containing pollen, and the ovarium being entirely obliterated, traces 

 of the original structure are to be seen in the bifurcated filament analogous to the two 

 stigmas." — p. 1 1 3. 



All these various forms are illustrated by figures.

1. Jungermannia ulicina, i^ayXoi). Stem creeping, filiform, branched: leaves dis- 

 tichous, roundish-ovate, concave, bilobate, inferior lacinia much the smaller, involute ; 

 stipides ovate, bifid : fruit axillary ; perichaBtium three-leaved, compressed, two upper 

 leaves narrow at the base, roundish-oblong, inner margins incurved; lower leaves ob- 

 long-ovate, bifid. 



On stems of Ulex europseus and Erica cinerea, " on wet banks fa- 

 cing the north, over Finnehy river, near Kenmare, Co. of Kerry; (T. T.) 

 At Dolgelly, North Wales ; Mr. W. Wilson." 



A minute species, bearing a strong resemblance to J. minutissima, 

 Sm. -y from which it may be distinguished by the presence of stipules,
