1869, 495. — According to the original description J. A. Schultes meant a plant 

 with rather broad and elongated leaves and conspicuously interrupted spikes (»Die 

 Blumen in entfernt stehenden Quer]en>). Such forms f. pinguis Tis., 1. c. n. 128, 

 and f. zosteroides Fischer, ]. c, 125, also seem to be. — F. incrustalus Tis., 1. c. n:o 

 128, I place here, though with some doubt. By its broader basal leaves it forms a 

 transition to the var. zosteraceus Fr.

 i>Hull, Yorkshire, 7 sept. 1853, From Charles C. Babington (Cambridge)-) (hb. Upp- 

 sal.), by Babington himself labelled P. flahellatus. This is without doubt the true 

 P. flabellatus: of high growth, upper internodes 50 mm long, lower ones longer, 

 sheaths rather long, lower stem-leaves rather broad, upper ones narrower, branch- 

 leaves very narrow. Fruit large, of usual form, without prominent keel. — Stoke 

 Heath, Warwickshire 1855. T. Kirk (hb. Lund.). — Germany, BavaTia,, Bamberg, 02, 

 Fischer (hb. Stockholm.). 



f. dichotomus Wallr., Sched. crit. 1822, 67. — P. Vaillantii Roem. & Schult. 

 Syst. veg. Ill, 1818, 514. — Distinguished from the preceding only by the shorter and 

 more dense spikes: spica pauciflora, Wallr. The peduncle also seems to be shorter 

 than in general. I have seen specimens from Denmark »Jordbroa, 97, J. Baagoe» 

 (hb. Stockholm.) and »Nibsa, 99, J. Baagoe» (hb. Stockholm.). 



f. sublatifoliiis n. f. — Folia inferiora latiora (circa 2 mm); vaginae ut in var. 

 zoster acea. 



This form resembles var. zosteraceus in everything except the upper leaves which 

 are narrower: thus more like the usual form as to the upper part of the stem; as 

 to the basis, again, just hke v. zosteraceus. The same is the case with the following, 

 f. notahilis, besides being microcarp.

f. notabilis TiSEL., Potamog. suec. exsicc. Ill, 1897 n. 133: — Fructus minores, 

 ceterum ut f. sublatifolius. 



Being microcarp this form corresponds to f. coronatus of var. ungulatus. I can 

 record it only from the original locality: Siveden, Uppland, Bay of Norrtelje, 82, 

 Tiselius (hb. Stockholm., Uppsal., Lund, and Gotenb.). 



f. ulveiisis n. f. — Folia brevia, 30 — 40 mm longa.
