peclosum Schpr. mss.) ; an exaniinaUon of Schimper's 

 types of the former shows how the mistake of removing 

 certain specimens from Eurhi/nchiion arose. By one of the 

 type specimens of " IL Savatleri " Schimper has drawn a 

 rough sketch a capsule with a conical not rostrate lid. In 

 this specimen there are two capsules with hds of this 

 shape, but although closely intermixed with the Eitr/fj/n- 

 chiiim, and with setae apparently springing from it, closer 

 examination shows that these setae are really borne by 

 underlying stems oid. Pscudoleskea. The Eurhynchium is 

 identical with E. subspeciosinn.

This appears to me to be identical with H. plumaeforme 

 Wils. (1848). Bescherelle in comparing the species contrasts 

 only //. siibimponenSy and all the characters given in the 

 diagnosis agree with those of//, plumae forme. It may be 

 noted that Bescherelle says '' foliis subinicgm vix apice 

 sublilitcr dcnticulatis" ; in the type specimens of " //. lon- 

 gisetum " in Schimper's herbarium, however, many of the 

 leaves are somewhat sharply serrulate towards the apex just 

 as in //. plumaeforme.

p. 82 (1894). 



Through thekindness of theauthoritiesat the Herbarium 

 of Oxford University I have been able to examine the 

 material on which Boswell founded the genus Helmsia, 

 with its single (New Zealand) species, H. collina. The 

 type specimens, \vhich are without fruit, and consist 

 mostly of male plants, prove on examination to be 

 Lcptostomum maerocarpum (Hedw.) R. Br. Boswell 

 described (1. c.)the upper cells of his plant as each contain- 

 ing*' a large single granule ", and added ^' These bodies 

 are the most curious feature of the moss, and totally unlike 

 anything found in any other known lo me by specimen or 

 description '\ The structure described is, however, merely 

 the contracted '' primordial utricle ' of each cell (see Mull. 

 Syn. 1, p. \n\) with its contained chlorophyll granules. _
