Answer 9

Asteraceae, Orchidaceae, Fabaceae, Poaceae

Question 10

Fabaceae

Answer 10

many have N-fixing bacteria in swollen nodules on roots.

Roating soybeams (legumes) with corn (N-depleting crops)

Pulvinis at base of each leaf (swelling)

Question 11

Pulvinis

Answer 11

A swelling at the base of each leaf or leaflet in the fabaceae

Question 12

Subfamily Caesalpinioideae

Answer 12

Zygomorphic flowers

redbud (cercis)

Honey Locust (edible flowers)

Kentucky coffee tree (Gymnocladus)

partridge pea (Chamaecrista)

Senna (senna)

Question 13

Subfamily Mimosoidae

Answer 13

actinomorphic flowers, dense clusters

exserted stamens

Sensitive plant (pudica)–in greenhouse

Silktree (albizia julibrissin)–leaves close at night

Acacia trees

Question 14

Subfamily Faboideae

Answer 14

Zygomorphic flowers, perigynous, short, narrow hypanthium

diadelphous stamens (in 2 “brotherhoods” , 9 connate 1 distinct)

monadelphous stamens (“one brotherhood” 10 connate)

Question 15

Fabaceae subfamily Faboideae floral formula

Answer 15

dark 5 means some of which are connate (supposed to be dotted)

Question 16

Fruit of Fabaceae

Answer 16

legume–dry dehiscent druit

from 1 carpel, dehisces along 2 sides

embryo usually large

ex: pea, soybean

peanut (does not dehisce)

Question 17

Economically important Fabaceae (need to know)

Answer 17

peanut

garbanzo bean, chickpea (same thing)

soybean

lentil

bean

pea

broadbean

carob

alfalfa

clover

Question 18

Other species of fabaceae

Answer 18

Cladrastis (yellowwood)

Lupinus (lupine)

Lathyrus ( everlasting pea)

Lotus corniculatus (birdfoot trefoil)

Coronilla varia (crown-vetch)

Melilotus officinale (sweet clover)

Pueraria montana (kudzu)

Question 20

Answer 20

Acacia, Mimosoideae

actinomorphic, dense clusters

Question 21

Answer 21

sensitive plant, Mimosoideae, actinomorphic, dense clusters

changes in pressure vary the orientation of leaves by causing pulvinus to move

Question 22

Answer 22

Kentucky coffee tree, Cesalpinioideae

slightly zygomorphic

paraphyletic to the monophyletic Faboideae and Mimosoideae
