XIX. An Account of the Indian Species of Juncus and Luzula. By Davin 
Doÿ Esq., Libr. L. S., Prof. Bot. King's Coll. Lond. 
Read January 15th, 1839. 
THE Junceæ, like the other Gl umaceous families, but especially the Cypera- 
cee and Graminee, bave a very wide geographical range, extending through- 
out the globe from the equator to the polar regions, and affording examples 
of the occurrence in both hemispheres of the same species, or at least of 
forms too closely allied to admit of their being ranked as distinct species, as 
for instance Juncus effusus and maritimus, and Luzula campestris ; but the 
Cyperaceæ afford still more numerous examples, and among others may be 
mentioned Carex cæspitosa and Pseudo-Cyperus, Cladium Mariscus, Scirpus 
lacustris, triqueter, and maritimus, Isolepis fluitans and setacea. 
The number of species collected by Dr. Royle in Northern India is eight, of 
which seven belong to Juncus, and one to Luzula. This last is common to 
Europe, the northern parts of Asia, and Greenland. Of the seven Junci three 
are entirely new, two are identical with those contained in the Wallichian 
Herbarium, and two are generally diffused throughout Europe. | 
The linear, erect anthers, attached by their base to the filaments, and com- 
posed of two parallel cells, connate throughout their entire length, and their 
filiform, longitudinally papillose stigmata, combined with their habit and nar- 
row sheathing leaves, clearly establish a close relationship between the normal 
Junceæ and Cyperacee, notwithstanding the reduced condition of the perian- 
thium and ovarium, the uninclosed embryo, and entire leaf-sheaths in the 
latter family. 
The Junceæ evidently form the transition from the Glumaceous to the Peta- 
loid Monocotyledons, being connected on the one hand by Narthecium with 
Asphodeleæ and Melanthaceæ, by Kingia and Calectasia with Commelinee and
