_Arrhenatherum_--short stolons, sometimes bulbous. _Holcus lanatus_--creeping. _Alopecurus pratensis_--long stolons. _Anthoxanthum_--slightly stoloniferous. _Agrostis alba_ (var. _stolonifera_)--long stolons and runners. _Digraphis_--long stolons. _Poa pratensis_--long stolons. _P. trivialis_--runners only. _Festuca heterophylla_, Lam.--a variety of _F. ovina_ with slight stolons. _F. rubra_ (Linn.)--a variety of _F. ovina_ with long stolons. _Bromus erectus_--no stolons. _B. inermis_--long stolons. Creeping below ground and truly stoloniferous. _Agropyrum._ _Elymus._ _Psamma._ _Poa pratensis._ _P. compressa._ _Agrostis alba_ (var. _stolonifera_). _Alopecurus pratensis._ _Brachypodium_ (slightly). _Bromus erectus_ (slightly). _Festuca ovina_ (var. _rubra_, Linn.). _F. elatior_ (slightly). _Briza_ (slightly). _Glyceria._ _Poa maritima._ _Melica._ _Arundo._ Tufted Grasses. _Milium._ _Agrostis alba_ (on downs, &c.). _Aira cæspitosa._ _A. flexuosa._ _A. canescens._ _A. præcox._ _A. caryophyllea._ _Avena pratensis_ (slightly creeping). _Arrhenatherum._ _Nardus_ (Fig. 2). _Hordeum sylvaticum._ _Lolium._ _Bromus._ _Festuca ovina_ (except some varieties). _F. sylvatica._ _F. Myurus._ _Dactylis._ _Cynosurus._ _Poa rigida._ _P. annua._ _P. trivialis._ _P. nemoralis._ _P. alpina._ _P. bulbosa._ _Molinia._ _Triodia._ _Kœleria._ Creeping above ground (with runners). _Holcus lanatus._ _Alopecurus geniculatus._ _Agrostis alba_ (var. _stolonifera_). _Hordeum pratense_ (slightly). _H. murinum_ (slightly). _Catabrosa_ (Fig. 4). _Cynodon_ (Fig. 5). Hackel has pointed out that a distinction must be drawn between the true nodes of the _culm_, and the swellings often found at the base of the _sheaths_ themselves over these: the latter are often conspicuous when the former are inconspicuous--e.g. most species of _Agrostis_, _Avena_, _Festuca_, &c. The nodes are of importance in the description of a few species only--e.g. they are usually dark coloured in certain _Poas_ such as _P. compressa_ and _P. nemoralis_; they are sharply bent in _Alopecurus geniculatus_, and may be so in other species if “layed” by wind, rank growth, &c. A point of considerable classificatory value is the shape of the transverse section of the shoot, which is correlated with the mode of folding up of the young leaf-blades.
