﻿420 ON THE BOTANY OF JAPAN. 



Wright gathered abundantly at the Bonin Islands,) is nearly related to C. aristata, E. 

 Br., of the Great Lakes and the Saskatchawan, which again (as C. orthostachys, Meyer, 

 which is referred to it by Dr. Boott) ranges from Kamtschatka through Siberia to 

 European Russia. C. Bo)i(fardi, by the way, is now ascertained by Dr. Boott to be 

 the C. Boottiana of Hooker and Arnott (Bot. Beech. Voy. p. 273), the earliest pub- 

 lished name, but singularly overlooked by Kunth, Boott, Steudel, &c. Meanwhile 

 another C. Boottiana, from the Southern United States, has been published and beauti- 

 fully illustrated, rendering it most desirable that the strict rule of priority should be 

 waived in this instance, and that the Bonin species should retain the name of C. 

 Bongardi. 



The Japanese Graminea of this collection have been studied by that excellent agros- 

 tologist, Colonel Munro. He finds only one new species among them, but that is a 

 most remarkable one, belonging as it does to a genus, Ehrharta, mainly South African, 

 yet with a few Australian representatives.* The grass which I had formerly taken for 

 T)-isetum cernuim, Trin., is a form of T. flavescens according to Colonel Munro, — 



C. pubenila, Boott, differt, spicis perigyniisque ovalibus obtuse triquetris, nee subglobosis, minoribus ; squamis 

 acutis; foliis bracteisque angustioribus. A C kucoclihra, Bunge, et C. Royleana, Nees, spicis evaginatis 

 minoribus ; basi styli discoidea artieulata, nee annulata. Loo Choo Islands.

* Ehrharta caudata (Munro, sp. nov.) : racemo simplici subcaudato ; pedicellis hispidis ; floribus 

 neutris intequilongis subulatis 5 - 7-nerviis quam glumis inajqualibus acutissimis trinerviis fere duplo longioribus, 

 hermaphrodite palea inferiori longe ai-istata; staminibus 3. Hakodadi, on the sides of mountains neai- 

 rivulets. 



" A very distinct species, in some respects approaching E. avenacea, Willd. (of Isle Bourbon). Stems 

 stoloniferous, a foot and a half high, with three joints. Leaves 6 to 12 inches long, nan-owly linear, scarcely 3 

 lines broad, ahnost smooth. Sheaths smooth or slightly hairy : upper ligules almost acute ; the lower obtuse, 

 slightly tinged with black. Raceme 6 inches long, slender, slightly bent to one side. Pedicels about a line 

 long, almost deflexed. Lowest neutral flower A^ lines, the upper 6^ lines, in length ; smooth, except on the 

 keels. Lower palea of the perfect flower about an inch long, inclusive of its remarkable awn-like termination, 

 inconspicuously fi-inged ; the upper palea fringed on the two nerves, which are very close together. Styles 2, 

 distinct to the very base. — This is perhaps Thunberg's Alopecuriis caudatus." W. Munro, 3Iss.
