Greenhouse

Desert Room Table 7-2, near the sign, holds most of the family in this room. Check out the squarish looking lycopodioides. Also, look at the largish on the Kincaid side of the table near the 7-2 sign, Echeberia glauca. This species has a determinate where a younger grows out of the axil of the flower below it. This type of inflorescence is called a cyme. What is the number in the top, right corner? ______(1 pt)

Outside Greenhouse Outside, in the beds in front of the room, are a lot of various Crassulaceae mixed in with others. Look for large, purple-pinkish Crassulaceae that are flowering. These are Sempervivum (houseleeks or liveforevers), they have 5-10 partially fused carpels at the center of each flower. If the chainlink gate just to the south of the GH is open, walk in and near the far end in the center is a Kalanchoe plant. Note the rare form of vegetative reproduction that occurs at the margins. Tiny plants with roots and leaves are produced and fall off to start new plants.

Medicinal Herb Garden Section D – narrow section between Section C (open, sunny, gravel-filled area just behind the northern bus stop on Steven’s Way closest to the greenhouse) and Section E (shady section across from College of Forest Resources + Winkenwerder Hall) Welcome back to the MHG, as you walk towards Section D look around at how many plants are blooming in families you know. Look at the west-most bed (N is towards the fountain) not part of the border area. You should see (broadleaf stonecrop). The flowers of this plant are well past, but it’s in the same genus as a plant you keyed after Lab Quiz #2. Please use the back of this sheet or your own paper to draw a simple diagram of the inflorescence (3 pts). You should include your best attempt at some leaves but spend the majority of your effort including details about the fruit. Label the fruit type and carpels and write down the carpel number. Please don’t remove any , these are here for us to see them but also to set new for future plant generations.
