Question
Good afternoon Dr I have a grass growing in my yard which appears linked to my bird feeder. The characteristics seem to be split between Echinochloa sp and Sorghum sp. The ligule is membranous measuring about 1 mm. The collar appears to be glabrous. There are several culms with inflorescence. One inflorescence has awns and another does not. The florettes are covered with fine hair. The roots appear to be fibrous without rhizomes. The culms appear a bluish-green. Thank you.
Answer
Dear califyank, it appears you have Sorghum bicolor. Echinochloa has no ligules on the upper leaves and does not have spikelets organized in pairs (with ligules in Sorghum and spikelets organized into pairs, one sessile and one paired). I hope this helps.
