kind, however, has yet been of certainty discovered. Footnote 4: Similar in all essential particulars to the germination of _Aregma_ (Plate III. fig. 45). Forty other species of _Puccinia_ have been recorded as occurring in Great Britain, to all of which many of the foregoing remarks will also apply—viz., such as relate to their two-celled spores being found associated with, and springing from, the same mycelium as certain orange-coloured one-celled spores; and also the main features of the germinating process. [Illustration: Plate IV. W. West imp. ] A very singular and interesting species is not uncommon on the more delicate grasses, being found chiefly confined to the leaves, and produced in smaller and more rounded, or but slightly elongated, patches (Plate IV. fig. 60). We have met with it plentifully amongst the turf laid down in the grounds of the Crystal Palace at Sydenham, and also on hedge-banks and in pastures. The spores are rather smaller than those of _Puccinia graminis_, but, like them, much elongated, slightly constricted, and borne on persistent peduncles. The most prominent distinction may be found in the apices of the spores, which, in this instance, are not attenuated, but crowned with a series of little spicules, or teeth, whence the specific name of _coronata_ has been derived (Plate IV. fig. 62). The Labiate family of plants and its ally the Scrophulariaceæ are also subject to the attacks of several kinds of Brand, a name, by the bye, often applied locally to the corn mildew and other similar parasites, and which may have originated in the scorched or _burnt_ appearance which the infected parts generally assume. In the former natural order the different kinds of mint, the ground-ivy, the wood-sage, and the betony, and in the latter, the water figwort and several species of veronica, or speedwell, are peculiarly susceptible; and on most a distinct species of _Puccinia_ is found. To provide against doubt which the less botanical of our readers may possess of the meaning or value of the term _Puccinia_, which has already occurred two or three times in this chapter, a brief explanation may be necessary, which more scientific readers will excuse.
