Am?nannia desertorum, spec. nov. — A course, rigid, more or less 

 scabrous papillose plant. Stem up to 50 cm. high, much-branched, 

 stout, subterete below, sharply quadrangular and narrowly winged 

 above, as are also the branches. Leaves lanceolate, acute or subobtuse, 

 up to 70 mm. long and 8 mm. broad, auricled at the base, feather- 

 veined, midrib prominent below, margins reflexed. 



All the axils flower-bearing. Peduncles absent or very short, not 

 reaching 1 mm. in length, stout, (1—) 3-(6)-flowered. Pedicels very 

 uniform in length, 1-2 mm., stout. Bracteoles minute, stiff, subu- 

 late. Calyx leathery, 8-nerved, in flower 2 mm. long, elongate- 

 campanulate, in fruit up to 2'5 mm. long, campanulate-semiglobose. 

 Teeth 4, small, broadly triangular, apiculate ; accessory teeth or 

 folds very small or absent. Petals 4, small, reaching 1 mm., obovate- 

 cuneate, purple, caducous. Stamens 8, inserted at about g of the 

 tube from below, sub-included. Style about as long as the ovary, 

 |-i as long as the capsule, rather stout. 

 Capsules 3 mm. long, crowded together, the upper \ ox }; not covered 

 by the calyx, reddish-brown transparent, shining. Seeds very 

 namerous, irregularly semiglobose, yellowish brown, shining. 

 This species has the habit of A. auriculata, but can easily be distingui- 

 shed by its inflorescence. Generally the whole plant is covered 

 with capsules. 

 The plant is common in the Rajputana Desert S. of Jaisalmer.
