Hab. : Cape Colony, Komgha Division, on grassy slopes near the 

 mouth of the Kei Eiver, alt. 200 ft., fl. Jan., Flanagan, 1029 (in herb. 

 Kew, Bolus, &c.) ; mountain slopes near Queenstown, alt. 4,000 ft., 

 fl. Jan., Galpin, 1713 ! Eland's Hoek, near Aliwal North, alt. 

 4,500 ft., F. Bolus (No. 10544 in my herb.). 



Described from living specimens of Flanagan's No. 1029. The 

 colour of the sepals is cold pale green, somewhat livid, faintly 

 mottled, the petals and lip pale lilac with purple edges near the 

 apex. The separation of the stipites and glands of the pollinia may 

 be a sport. I have not observed it before in any other species, but 

 found it identical in two flowers of Flanagan's 1029, dissected. The 

 species resembles E. laxiflora, Schltr., but is distinguishable by the 

 absence of any chin or projecting foot at the base of the column, as 

 well as by colour differences. In some of the Eulophice the colours 

 of the flower vary considerably, especially in the lip, and too much 

 reliance must not be placed upon them ; in others, especially the 

 unicoloured species, there seems to be little variation. 



Mystacidium, Lindl. 



(Note on the S. African species of this genus.) 



In my Icones Orchidearum Austro-Africanarum, under t. 7 

 (Angr&cum Gerrardii mihi), I endeavoured to show that the genus 

 Mystacidium should be restricted to those plants having the peculiar 

 bearded appendages to the rostellum, which were described by 

 Lindley in establishing the genus (Comp. to Bot. Mag., v. 2, 206). 

 These appendages being often of small size, and attached to an 

 organ which generally loses its shape in dried specimens, have 

 possibly been overlooked by European botanists, or, if seen, have not 

 been regarded as of generic importance. In respect to this genus 

 and Angraecum (as well as to other allied genera), great differences of 

 opinion have existed among orchidologists, and much inconvenience 

 has resulted therefrom. In the desire to refrain as far as possible 

 from adding to this, I have reconsidered the course adopted in the 

 work first above cited, and have concluded that it would be better to 

 change it. The chief characters adopted by Pfitzer (in Natilrliche 

 Pflanzcnfamilien, II. 6. 214, 216), and by Eolfe (in the Flora of
