 „ 294, line 19 from top. Of this tree, as of several others, the anatomical account is 

 deferred. In Tab. XCVI. the round scars on the trees, whence the dragon's blood is 

 cut, are indicated.

 „ 306. Mr C. B. Clarke has sent me the following notes regarding the plants I have 

 named Kyllinga monocephala and Heleocharis Gho3taria. ' Your Kyllinga mono- 

 cephala is K. brevifolia.' ' The Eleocharis is a very interesting plant. The E. albo- 

 vaginata, Bckl., is a plentiful American plant, comprising the greater part of 

 Chcetocyperus polymorpha of Nees — a very variable lot. Your plant is the same as 

 Boeckeler's var. 2, humilis, which you will see he finds in Mauritius. It differs from 

 the usual polymorpha (a green thing) in its rigid texture and f ermginous colour ; 

 but I have the same from South America and from Australia, where Mr Bentham 

 called it Eleocharis acicularis.'

„ 332. Mr Mitten sends the following correction : — " Since the list of Socotran mosses 

 was made out, which contains the species therein referred to the Anoectangium Mariei, 

 Bescherelle, Florule Bryologique de Reunion de Maurice, &c, p. 13, an opportunity 

 has occurred for the examination of M. Marie's own specimens collected by himself in 

 Nossi be, with the result that it is found to be altogether different from the species 

 found in Socotra, which may be described as follows : — 



" Anoectangium Balfouri, sp. n., pusillum caulis laxe csespitosus inferne radicellis 

 rufis intertextus innovationibus pluribus divisus ; folia inferiora fulva superiora sensim 

 majora viridia laxiuscule inserta patentia patulave leniter recurva sicca incurva con- 

 torta oblongo ligulata acuta subintegerrima nervo concolori percurrente canaliculata 

 dorso papillis asperulo cellulis omnibus minutis rotundatis distinctis areolata flos 

 fcemineus juvenilis tantum visa. 



" Caulis 1 cm., altus cum foliis ubi robustior 150 mm. latus. Folia majora 1 mm. 

 longa, 025 mm. lata. 



" In size and appearance this nearly resembles the species collected by the late 

 Bishop Hannington on Kilimanjaro, and to which was inadvertently applied the name 

 ' pusillum,' which, having already been used for two other species, should be changed 

 for that of ' Hanningtoni.' In this the leaves are more pointed, and have not the 

 prominent papillae on the back of the nerve. 



" Two other small species are known from this region near Socotra ; these are — 



"A. Hobsoni, sp. n., caules in csespites densos aggregati erecti foliis erecto paten- 

 tibus oblongo ligulatis apice latis subacutis paulum recurvis canaliculars nervo lato 

 concolori percurrente cellulis minutis rotundis obscuris basi ad nervum paucis qua- 

 dratis pellucidioribus perichsetialibus ovato-lanceolatis obtusis. 



" Hab. Aden. Major-General Hobson. 



" Caulis 2 cm. altus apice cum foliis humidis 2 mm. latus. Folia 1 mm. longa, 

 0"25 mm. lata olivaceo-viridia inferiora pallide fusca. 



" A. Schimperi, sp. n., perpusillum humile caulis gracilis inferne foliis parvis ovatis 

 acutis erectis remotiuscule insertis pallide fulvis apicalibus in comam congestis majo- 

 ribus erecto patentibus secca appresse sub contortis pallide viridibus oblongo ovalibus 

 obtusiuscule acutis sub apiculatis integerrimus nervo valido apice abrupto dorso pro-
