these are tricky. I am not familiar with all of them. Go to www.plants.usda.gov and put in the fruit in the search box and look at a picture of the seed. You will know when you see it. If it is not listed in their database, google the name and look at images.

Simple fruits can be either dry or fleshy, and result from the ripening of a simple or compound ovary with only one pistil. if there is one seed or one pit, it is simple

A multiple fruit is one formed from a cluster of flowers (called an inflorescence). Each flower produces a fruit, but these mature into a single mass.[17] Examples are the pineapple, edible fig, mulberry, osage-orange, and breadfruit.

An aggregate fruit, or etaerio, develops from a flower with numerous simple pistils.[14] An example is the raspberry,

these definitions are from wikipedia and there is also a chart on their page http://en.wikipedia.org/wiki/Fruit#Aggregate_fruit


inflorescence

Mahonia siamensis #1
inflorescence

Berberidaceae - W. China, Thailand
Siam Hollygrape, Siam Mahonia
Shown: Growth habit with clustered inflorescences in bud stage

"Mahonia is a genus of about 70 species of evergreen shrubs in the family Berberidaceae, native to eastern Asia, the Himalayas, North America and Central America. They are closely related to the genus Berberis. Botanists disagree on the acceptability of the genus name Mahonia. Several authorities argue plants in this genus should be included in the genus Berberis because several species in both genera are able to hybridize, and because when the two genera are looked at as a whole, there is no definite morphological separation.[1] Mahonia typically have large, pinnate leaves 10-50 cm long with 5-15 leaflets, and flowers in racemes(5-20 cm long).

"The genus name Mahonia honors the Philadelphia horticulturist Bernard McMahon who introduced the plant from materials collected by the Lewis and Clark Expedition.

"The type species of the genus is Mahonia aquifolium, (Oregon-grape) from the Pacific coast of North America. The species name aquifolium attributes the leaf to be holly like and means wet foliage." (Wikipedia)
