Common Name: ELM
Habit: Deciduous. Leaf: serrate (or doubly so), base generally oblique, 2° veins straight, parallel, extending to margin, each ending in a tooth; axils of 2° veins generally with prominent tufts of hairs. Inflorescence: umbels or short racemes in leaf axils on old wood; flowers sessile or pedicels 7--17 mm. Flower: bisexual; calyx generally bell-shaped, lobes 4--9; stamens 4--9, exserted; ovary strongly compressed; style divided to base, branches spreading.
Note: Widely cultivated as street trees; flowers, fruit needed for identification.

(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurence).	Data provided by the participants of the Consortium of California Herbaria. MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window. Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location. Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues. READ ABOUT YELLOW FLAGS CCH collections by month Duplicates counted once; synonyms included. Species do not include records of infraspecific taxa, if there are more than 1 infraspecific taxon in CA. Blue line denotes eFlora flowering time (fruiting time in some monocot genera).
