Alliaceae
Allium tricoccum
Allium tricoccum,
Wild Leeks,
Alliaceae
Allium tricoccum, Wild
Leek -- Leafs first in the
early spring and then in
summer after the leaves
have senesced, puts up a
flowering stalk.
Allium tricoccum
seeds are
produced in mid
autumn.
Note the fruit is a
loculicidal
capsule- here split

A bulb is a short underground stem-- usually used to store
nutrients. In these lily bulbs: each scale is a modified fleshy
leaf that will produce new roots and shoots when planted.

Onion Bulb
Hemerocallis (Hemerocallidaceae, Asparagales) contractile
roots. This was 5 cm deeper after approximately 10 months
(1/3/94 - 10/27/94). Contractile roots act by expanding laterally
and shrinking in length. Lilies, Daffodils, Crocuses,
Dandelions (yes dandelions!) have contractile roots!
From Putz, N. 1998. Underground plant movement. V. Contractile root tubers and their importance to the mobility
of Hemerocallis fulva L. (Hemerocallidaceae). Int. J. Plant Sci. 159: 23-30.
Hemerocallus if
planted too deep
will move up. By
making a long
shoot with only
scale leaves,
developing
adventitious roots
higher up and
aborting the older
section of shoot
and roots.
(also from Putz 1998)
Ruscaceae (including the Convallariaceae)
Smilacina stellata
Smilacina racemosa
Maianthemum canadense
Polygonatum pubescens
Ruscus “leaves”
are modified
flattened
photosynthetic
branches. Note
flowers come
right out of these
branches!
Stems of Ruscus
were bundled to
clean butcher’s
blocks. Hence the
name Butcher’s
Broom Family
Two species of Smilacina, False Solomon’s Seal, in the Convallariaceae
(Lily-of-the-Valley Family) Note small 6-tepaled flowers.
Smilacina stellata Note small bisexual flowers, 6 distinct tepals
(may be fused into a bell in other species), 6 anthers, NO spots,
superior ovary.
Smilacina stellata fruit = berry.
Iridaceae

Crocus sativus
Saffron crocus
(The spice, Saffron, is
made of the stigmas)
6 Tepals
3 Stamens
3 Carpels(3-parted stigma)
Saffron is the long red stigma of the saffron crocus (Crocus
sativa)
