hWng those of J. castancus than of J. trif^lumis. Perianth leaves 

 J inch long. Capsule only slightly exceeding the perianth, 3-sided, 

 each side obcordatc. Seeds similar to those of J. triglumis, but 

 shorter and with considerably smaller appendages. 



Mr. Bentham joins J. triglumis to J. bigluinis. Perhaps he has 

 seen specimens of J. triglumis with pseudo-lateral flowers misnamed 

 J. biglumis, for the two species have nothing in common but tlifir 

 small size, few flowers, and appendaged seeds.

Perennial. Stems solid, not articulated. Leaves all radical, sheath- 

 ing the base of the stem, resembling the barren stems, not jointed; the 

 sheaths sometimes Avithout any lamina. Flowers numerous, in small 

 fascicles, collected into an umbellato-corymbosc panicle or head, which 

 is at first pseudo-lateral, from the lowest bract forming an apparent 

 continuation of the stem, but in fruit it becomes more evidently termi- 

 nal. Seeds with the testa produced into a short appendage at each end.

Cffispitose, growing in large dense circular tussocks. Rootstock 

 very shortly creejiing, its branches with the stems placed close together 

 one before the other. Stems very numerous, wiry and rigid, terete, 

 smooth when fresh, finely striate when dry, the barren ones much 

 more numerous than the fertile, and terminating in a very acute pun- 

 gent point. Sheaths long, chestnut, shining ; a few of the upper ones 

 terminating in a lamina wdiich is extremely similar to the barren stems. 

 Panicle at first pseudo-lateral, afterwards nearly terminal. Lowest 

 bract resembling a continuation of the stem, from as long as to twice 

 as long as the panicle, and termmating in a rigid point like tlie 

 barren stems and leaves. Flowers in fascicles of 2 to 4, arranged 

 in a rather dense umbellato-corymbosc panicle, with the loAver 

 branches diverging and sometimes so short that the inflorescence forms 

 a bead. Perianth leaves oval-lanceolate, the outer ones subacute, the 

 inner obtuse and usually emarginate from the great development of 

 a white scarious membranous border ; all of them about half the 

 length of the capsule, yellowisli brown with chestnut tips. Capsule
