Atriplex glabriuscula — bracted orache

Copyright: various copyright holders. To reuse an image, please click it to see who you will need to contact.

Facts

Bracted orache is widespread on Europe's Atlantic coast. It is similar to, and often grows together with, hastate-leaved orache (Atriplex prostrata) in salt marshes and beaches, and the two are sometimes confused.

Habitat

Coastal beaches (sea beaches), intertidal, subtidal or open ocean

From Flora Novae Angliae dichotomous key

3.  Atriplex glabriuscula Edmondston N

bracted orache. Atriplex patula L. var. oblanceolata (Victorin & Rouss.) Boivin • CT, MA, ME, NH, RI. Saline marshes, sea beaches and strands. Atriplex glabriuscula and A. prostrata are morphologically similar in some respects (e.g., usual leaf blade outline), frequently grow together, and possess a similar chromosome number. Therefore, it is no surprise that these two species are sometimes confused, especially when A. glabriuscula shows variation in the proportion of the inflorescence that possesses leafy bracts. In addition to the characters used in the key, they can be separated by the size of the brown fruits and length of the carpellate bracteoles. In A. glabiuscula, they are 2.5–3.9 mm wide and 5–13 mm long, respectively. In 
 A. prostrata, they are 1.5–2.5 mm wide and 3–5 mm long, respectively.

Native to North America?

Yes

Sometimes confused with

Atriplex prostrata:
inflorescences with leafy bracts only near base and brown fruits 1.5--2.5 mm wide (vs. A. glabriuscula, with inflorescences with leaf bracts nearly throughout and brown fruits 2.5–3.9 mm wide).
