cola de caballo (horse's tail)

Arisaema macrospathum


The leaf is similar to those of other Arisaema species but can be quite robust with some petioles reaching close to a meter in height. The most distinctive characteristic about the "flower" is the extraordinarily long spadix that sticks out of the inflorescence like a tongue.


found in Mexico. (The other species are A. triphyllum and A. dracontium whose distribution ranges also includes the United States.) It is a relatively common plant in oak and pine-oak temperate forests. The flowers appear in April-May just before the foliage starts to emerge. Grows on the banks of the rivers
