1904.] J. R. Drummond — On a new Scirpus from BelncMstan, 8fc. 143 



Boeckeler in the XXXVIth issue of Linnoea (1869 — 70) described 

 the Oyperacese of the Royal Hb. Berlin, and has given a key to the 

 species of Scirpus taken up by him. This has a group under the first 

 main section (A. squamse apice rectse) which is distinguished by the 

 segments of the perigonium being fimbriate-ciliate : this group includes 

 three species, viz : — 



S. suUilatus, — Vahl 



8, triqueteVi — Linn. 



8. riparius, — Presl. 



It may b9 noted that these are referred to a sub-section having 

 glumes entire (cquamse integrse) which is inapplicable to several of 

 the forms which he has assigned to 8. triqueter. 



Moreover he has reduced 8. fimhrisetus Del. (or as he gives it, fol- 

 lowing a misprint in the Index to Steudel, ^^ fimhriatus " ) and 8. litoralis 

 of Schrader to 8. triqueter of Linnaeus, which is certainly erroneous. 



His 8. riparius of Presl. is made up of several species of Steudel's 

 plus some others subsequently edited, all American, of which most 

 appear to be referable to the sub-genus " Malacochsete " ; but for the 

 purpose of this note the American forms may be neglected. 

 Under *' 8. suhulatus " he cites : — 



(i) 8. suhulatus Vahl (but had apparently not seen authentic 



specimens), 

 (ii) Malacochsete pectinata Nees, in whose Hb. he seems to have 



seen a specimen (from Wight probably) ; 

 (iii) Walllch Hb.— No. 3506 B ; 

 (iv) 8. arahicus Nees et Ehrenb in Hb. Berol ; 

 (v) Thwaites No. 831 from Ceylon ; and 



(vi) Boivin No. 3051 from Mayotte, which is no doubt the island 

 of Mayotta, one of the Oceanic group of the Comoro Isles, 

 half-way between the Mozambique Coast and Madagascar. 

 As observed above, Thwaites No. 831 is in Hb. H.B.O. and is 

 marked as 8. pectinatus Roxb. 



8. Pterolepis Kunth ( —Pterolepis scirpoides of Schrader's Analecta 

 Fl. Cap.) he makes var. B of 8, suhulatus without discussing the 

 strongly marked diognosis which is given for the Cape plant by its 

 author. The Mascarene plant is not improbably the same as Schrader's 

 Pterolepis or closely allied to it ; but for want of specimens the writer is 

 unable to suggest a place for either form. 



In the Flora Austral. (I.e.) it is pointed out that Boeckeler was 

 wrong in identifying 8, litoralis with 8. triqueter of Linnaeus and
