glabro ; capsula perigonium excedente, glabra, circuitu oblonga ; 

 bracteis membranaceis squamfeformibus obtusis, minutis, pedicellis 

 post anthesin paulo elongatis filiformibus glaberrimis, erectis. 



Habitat in regione austro-orientali: in cacumine montiura prope 

 Queenstown, alt. 4500 ped., Jan. 1896, i^;. E. Galpin, No. 1944. 



In its leaves our plant resembles somewhat E. lance if folium 

 Jacq., but, besides the long slender petiole and the very thin texture 

 of the leaf itself, it is well distinguished by the very lax-flowered 

 inflorescence, the bracts, and the larger flowers on very slender 

 pedicels. The thin texture of the leaf is very remarkable in the 

 genus, and has to my knowledge never been observed before in any 

 other species. E. Bellcndeni differs from E. dissiti/lorum by the 

 different leaf and a very different inflorescence. The flowers are 

 white, with a greenish centre-line on the back of the three outer 

 segments.

A low thorny bush, 35 cm. high ; the branches, the longest of 

 which reaches 32 cm., are 2-5 mm. in diameter in the lowermost 

 internodes, 2 mm. and less in the upper. The leaves have fallen 

 except in the upper parts of the branches ; they are 3-5-4 cm. 

 long, 1-0-1 -3 broad. The shoot in the leaf-axil branches im-

 needle-like spines about 1-5 cm. long. The dense spiny spike is
