398 HORTIJS GKAMINEUS WOBURNENSIS. 



managed under this superior system of tillage, except when in- 

 troduced by having seed from other farms where broad-cast 

 sowing is practised. 



Flowers in the first week of July, and the seed is ripe about 

 the beginning of August. The seeds vegetate quickly after being 

 sown. 



LOLIUM arvense major. Larger Short-awned Annual Darnel. 

 Fig. 1 . A cutting of the grass. Native of Botany Bay. 



Lolium arverise minor. — Fig. 2. A cutting of the grass. Native 

 of Britain. 



Lolium arvense. Short-awned Annual Darnel. 



Specif c character : Corolla slightly awned ; spikelets as long as 

 the calyx ; florets elliptical ; stem very smooth. Sm. Engl. 

 Fl. i. p". 174. 



Obs. — Rather smaller and smoother than the preceding species, 

 of which it is probably only a variety. See Sm. Engl. Fol. 



Lolium temulentum, var. Slender-awned Annual rye-grass. 

 Hort Gram. Fol. 301. 



QIjs, — This differs from the common annual bearded rye-grass 

 in having the calyx longer than the spikelets ; spikelets 

 more cylindrical, resembling in this respect the Lolium tenue ; 

 awns very weak; leaves smoother; root-leaves spreading, 

 pointing horizontally. It partakes of the characters of the 

 Lolium tenue, L. arvense, and L. temulentum ; but evidently 

 approaches nearest to the Lolium arvense, as pointed out by 

 Sir James Edward Smith. It is said to be a native of New 

 Holland, being marked as such on the envelope of the seeds 

 I received ; but as it withstands the effects of the severest 

 frosts, which utterly destroy the common sort, it is most 

 probably, as the late Mr. Sowerby observed, only a British 

 plant returned from transportation.
