S. Geum, t. 1561, but particularly in many grasses, as the common cultivated Oat, and Avena strigosa, t. 1266; in this tribe the branches of the panicle are mostly semi-verticillate; see Aira aquatica, t. 1557. A divaricated panicle is still more spreading, like those of Prenanthes muralis, t. 457, and Spergula arvensis, t. 1535; the last being dichotomous or forked. A dense or crowded panicle, coarctata, is observable in Milium lendigerum, t. 1107, and Agrostis stolonifera, t. 1532, but still more remarkably in Phleum paniculatum, t. 1077, whose inflorescence looks, at first sight, like a cylindrical spike, but when bent to either side, it separates into branched lobes, constituting a real panicle.


Thyrsus, a Bunch, is a dense or close panicle, more or less of an ovate figure, of which the Lilac, Syringa vulgaris, Curt. Mag. t. 183, Tussilago hybrida and Petasites, Engl. Bot. t. 430, 431, are examples cited by Linnæus. I presume likewise to consider a bunch of grapes,
