specimens of var. valiilius Cardot to Braithwaite's variety. The 

 records for vice-counties 60 and 61 (and probably that for 48) refer 

 to var. validius Card, and should be so amended. Mr. Horrell in 

 The European SphagnacecB quotes No. 44 of the Exsiccata under 

 both S.Ji mhriafum iind S. squarrosum. There are two specimens from 

 the same locality (Eskdale, Yorkshire, Aiiderson) in Mr. Slater's 

 copy ; I refer both to S. Jimhriatum. In this copy there are also 

 several loose packets collected by Anderson in the same vicinity at 

 different times. Some of these belong to S. Jimhriatum var. laxi- 

 folium Warnst., others — labelled b}^ Anderson ^S*. Jimhriatum var. 

 squarrosulum Anderson, Eskdaleside Moor, 2 Oct., 1875, and S. Jim- 

 hriatum var. rohustior Anderson ?, 18 June, 1875 — belong to S, 

 Jimhriatum var. rohustum Br. On the latter packet Anderson has 

 written *' To say the least of this, it is a good variety ; I have never 

 collected Jimhriatum like it in an}^ other locality." With it is a 

 letter from Anderson to Slater, written from Whitby, June 1875, 

 from which I extract the following: "I send herewith the plant 

 alluded to in my list — I have sent it to Braithwaite and he says, ' I 

 shall send this to Lindberg when I \mte again.' You will see that 

 it is coming into fruit, so that in the course of a month I shall be 

 able to send you plenty of it in that state. I collected it last 3^ear 

 in the same locality, nay from the same identical 9 feet tuft, but not 

 then in fruit. Notice the ascending branches at the apex of the 

 ])lant, and the naiTow border on the stem leaves — altogether different 

 to the ordinary form of S. Jimhriatum. I sent it to Braithwaite as 

 under * No. 1. S. Jimhriatum vsiV. rohustior? Anderson (a sad piece of 

 presumption this).' Look at it well tomorrow and write me fully on 

 it by that day's post." There is no doubt Anderson first detected 

 and even named this variet}^ but did not describe or publish it. 

 Warnstorf's description is excellent, but does not cover all the forms, 

 which are as follows : — 



(«) forma laxum Wheldon. Pale yellowish-green deep tufts 

 15-25 cm. high. Fascicles distant. Branches elongate, spreading, 

 longly and gradually acuminate, 2-3 cm. long. St. 1. broadly spatu- 

 late, i"14-l'3 long, and usually nearly and sometimes quite as wide. 

 L. lax, broadly ovate-lanceolate 2 X 1"14, erect arcuate with spreading 

 points, sometimes distinctly squarrose. Braithw. Exsicc. No. 44. 

 liight-hand specimen. Eskdale, Yorks, S. Anderson. This plant 

 rivals S. squarrosum in stature ; someone, probably Slater, has 

 crossed out the title S. Jimhriatum., and written in S. squarrosum var. 

 laxum Braithw. I have, however, examined the chlorophyll cells in 

 section and they are situated on the inner surface of the leaf. 



{h) forma jpycnocladum Wheldon. Shorter (10-15 cm.). Fas- 

 cicles denser. Branches much stouter, more densely leaved, shorter 

 (l;t-2 cm.), suddenly acute, the upper ones erect-patent. The lowest 

 branches are more laxly leaved. Leaves of upper branches imbricate, 

 of the lower erect patent to subsquarrose. Braithw. Exsicc. No. 44. 

 Left-hand specimen. Eskdale, Yorks, Oct. 1875, Anderson. 



(c) forma comjyactum Wheldon. Grey-green, short (5-8 cm.). 

 Bi-anches cumvilate, arcuate-spreading to dellexed (l|-2 cm., occa- 

 sionally longer). Leaves densely imbricate or with the points only
