8-24-34 subtending bract, and branch awn-desc. (S.W.) B.sep. Bencheni (SWK) root sheath, subtending bract and branch awn-desc (SWK) except that shortest branch has 2 apiclelets. 8-27-34 Arrhenatherum elatius Murr & Koel. Coats III:59; BWH:542; $141; BMJCP:114, SVK I:60 = Avena elatior BWH 359 Fl. glion var hiaristatum Peters SW II:28. Puzzled R.B.K for a long time because the upper fl has an awn-almost as quite as long as and very similar to the awn of lower fl. Note however that in this case the awn of upper fl is placed midway or back 1/3 lemma i.e (this lower than in the typical plant) awn-desc will in the books and as frequently found higher than awn on lower lemma. Many plants have all apiclelets awn-desc. but others have just apiclelets with the typical blunt awned upper lemma. This is plant R.B.K has been unsuccessfully trying to identify as an Avena. On an earlier occasion she thought she found a normal vary in lower fl of apiclelet but this may have been a mistake as none of the books mention the possibility. 8-28-34 Poa compressa L Coats III:611, BWH 362, BWH 599, $155; SVK I:68 F-2. glion R.P station.
