trimerism occur in the same genus — whether in the same spe- 

 cies, is unknown to me. 



In all the forms of this little plant the leaves are 2-12 lines 

 long and i line wide, filiform, but fleshy, on their lower part 

 strongly carinate below and grooved above, flattened towards 

 the tip; axillary stems, or properly peduncles, with one or 

 two leaves at their base, naked upwards and much longer 

 than the leaves, bearing at the apex 1-5 or 6 flowers in the 

 axils of membranaceous bracts, half as long as the sepals or 

 smaller; flowers 1-1| lines long; sepals green with red, outer 

 ones sharp pointed, inner ones rather broader; seeds 0.23- 

 0.28 line long, their length being equal to 1| or l£ diameters; 

 4 or 5 faint ribs visible and between them a well marked 

 cross-lineolation. The central peduncle is really terminal 

 and bears the earliest flowers, the lowest axillary one is the 

 next in the progress of development, and then follow the 

 others in ascending order, so that the one next to the termi- 

 nal one bears the latest flowers; in the smaller specimens the 

 leaves of the main stem and, consequently, the peduncles are 

 alternating, or in \ order. 



Van a is the largest one with a remarkably long style, about 

 3 times as long as the ovary, and much exceeding the sepals 

 and the very long anthers; its seeds, however, are among 

 the smallest of the species; — var. (3 is intermediate in size be- 

 tween both others ; when the heads bear 2 flowers, these are 

 arranged exactly like those of J. pelocarpus, with 2 lower 

 bracts, bearing the flowers in their axils, and a third sterile 

 one at the inner base of the upper flower; sometimes this 

 upper flower is dimerous; — var. y is the smallest one only 

 lr-1 inch high ; its single flowers have 2 bracts at their base, 

 Just as those of any other single flowered Juncus, and alter- 

 nating with the exterior sepals, the stamens, carpels and stig- 

 mas; the inner sepals and the valves of the capsule are 

 opposed to them.
