Linn. Trans V. 18 p. 317. "D. Don on Indian species on Juncus & Luzula." — The Junceæ evidently form the transition from the Glumaceous to the Petaloid Monocotyledons, being connected on the one hand by Narthecium with Asphodeleæ & Melanthaceae, by Kingia & Calectasia with Commelineæ & Palmeæ, & by Burmanniaceæ with Irideæ; & on the other hand by means of Restiaceæ with Xyrideæ & Cyperaceæ — good case of alliance, complicated, & through genera & families.— One ought to know which of these genera are Petaloid & which Junceaceæ.

p. 322 enumerates points in which "establish intimate relationship between (a certain section of) Juncus & Narthecium, as Mr Brown has long ago suggested, & the passage from the latter genus, through Anthericum to the Asphodeleæ is rendered very clear" Is anthericum one of the Asphodeleæ — (case to test Waterhouse's theory.)

p 325. Luzula spicata, "this interesting plant differs in some points of structure from the typical form of Luzula spicata"— yet does not think different from the Europæan species — yet seeds not half the size & with less prominent hilum — capsule & sepals different shape — from Kunawur. = two forms agree so remarkably in habits =
