Plant Tax Lab Quiz (Labs 13 and 14)

Family Ericaceae (common name, habit, leaves, FF, petals, androecium, pollination type)

Common name: Heather or Blueberry family

habit: gen. shrub to tree, herbaceous members do exist, sometimes parasitic

leaves: simple, sometimes coriaceous, alternate arrange, sometimes revolute margins

FF: *, 5, 5 (fused), 10 (epipetalous), 5 (fused; either superior or inferior)

petals: arrange in 2 different ways - urceolate and bell shaped

androecium: poricidal anther dehiscence

-buzz pollination

Arctostaphylus - common name, habit, leaves, ovary, fruit type, flower shape

common name: manzanita

habit: shrubs

leaves: isofacial, small, coriaceous

ovary: superior

fruit type: berry

flower shape: urceolate

Gaultheria - common name, habit, leaves, ovary, fruit type, flower shape

common name: salal or wintergreen

habit: shrubs

leaves: coriaceous

ovary: superior

fruit type: ecoberry (ecological fruit/berry) - capsule on inside of fleshy calyx

flower shape: urceolate

Rhododendron - common name, habit, leaves, ovary, fruit type, flower shape

common name: rhododendron or azalea

habit: shrub

leaves: coriaceous

ovary: superior

fruit type: capsule

flower shape: bell shaped

Vaccinium - common name, habit, leaves, ovary, fruit type, flower shape

common name: huckleberry

habit: shrub

leaves: EITHER evergreen + coriaceous OR deciduous + non-coriaceous

ovary: inferior

fruit type: berry

flower shape: urceolate

coriaceous

leathery/thick and tough leaves

revolute

leaf margins rolled underneath

epipetalous

stamens fused to petals

poricidal anther dehiscence

anthers do not open up until bee comes by and vibrates it to release pollen = buzz pollination

isofacial

look same on both sides; undifferentiated adaxial and abaxial sides to leaf

Windy Woody - all taxa have

• catkin

• all leaves are simple and alternate in arrangement

• all have habit of trees or shrubs

• highly reduced perianth and unisexual flowers (either staminate or pistillate, never both on same flower)

catkins

• spike or spike-like infl

• unisexual (staminate or pistillate)

• generally wind pollinated; pendant = wind, erect = animal

• usually pendant in position

• often have bracts - look different depending on type of catkin
