perianth ; outer petals, both inside and outside, whitish, witli

In flower at Mapellapoede, N. E. Kalahari (18 miles North of 

 Serowe on the road to Lake N'Gami), Aug. 29th, 1903. 



I have pleasure in naming this species after my friend. 

 Dr. J. B. Greathead, who accompanied me on a trip to the N. E. 

 Kalahari, and who first called my attention to it. 



A. Greatheadii is allied to A. grandideutata, Salm-Dyck, 

 which, however, does not develope the thick caudex of the formei", 

 and further has the leaves spotted on both surfaces, the perianth 

 tube has not such a decided "bulb" at the base, it is scarcely 

 curved at all, and the stamens and style are more exserted. 



Aloe hauiaugivatensis, Schonl. n. sp.--Acaulescent, branching 

 only underground. Leaves about 12 in a dense rosette, ascending 

 and gently recurved at the tip, narrow lanceolate, frequently 

 subensiform in the upper third, 1 cm. broad low down, 30-35 cm. 

 long (in cultivated specimens, about | this length in wild ones), 

 c. 1'5 cm. thick in the centre, nearly flat on the innei- surface, 

 strongly convex on the outer, on both surfaces dark green with 

 large oblong whitish spots, which are, especially in the lower 

 portion, more or less confluent and form irregular transverse bands 

 which are more numerous on the outer than on the inner surface 

 and vary considerably in different individuals, margin spiny 

 throughout, and a few small spines also in the median line on the 

 outer surface near the tip, marginal prickles deltoid-acuminate, 

 sometimes slightly curved, 2-1 mm. long, white or (in older leaves) 

 brown at the tip, separated by slightly rounded interspaces of 

 variable length (3-13 mm.). Inflorescence subterminal, a lax 

 panicle 140-150 cm. high, unbranched part of the peduncle with- 

 out empty bracts, 10-50 cm. long subterete, subglaucous, bearing at 

 wide intervals 1 or 5 branches about 38 cm. long with racemes about 

 21 cm. long, the bract bearing the first lateral raceme c. 1 cm. long, 

 sometimes with a few marginal and terminal prickles near the 

 tip, the upper smaller and quite smooth, all lanceolate, pale green, 

 longitudinally striate, clasping, floriferous bracts lanceolate- 

 cuspidate c. 12 mm. long. Flowei-s very laxly but irregulai-ly 

 distributed, patent or cernuous, pedicels 7-9 mm. long, those of the
