12 Cactaceae genera/1400 species. Cactaceae (Cactus family) Succulent stems, variously shaped (cylindrical, fattened); Leaves are ephemeral (quickly falling) or reduced; Axillary buds specialized into cushion-like areas, called areoles (=short shoots), bearing spine clusters (modified axillary shoot leaves) and sometimes spine-like hairs (glochids). Flowers with many tepals usually united at the base into a hypanthium, many stamens arising from the hypanthium, inferior ovary of 3-numerous f used carpels with parietal placentation. Fruit berry. BETALAINS present;

13 Quizaceae (Quiz family) In a beautiful evening, when you are walking your dog and passing by your neighbor s yard, there is a gorgeous plant with many reddish zygomorphic flowers draws your attention. When you take a closer look, each flower has three sepals, three petals, three stamens, three stigma lobes and an inferior ovary, which of the following families does this plant belong to: A. Liliaceae B. Orchidaceae C. Iridaceae D. Magnoliaceae E. Ranunculaceae

14 Relationship between Cactaceae and Portulacaceae Portulacaceae is not monophyletic Applequist and Wallace, 2001, Syst. Bot. 26:

15 Portulacaceae - 20 genera/450 species. PNW flora include Montia (miner s lettuce, Claytonia (spring beauty), and Lewisia (bitterroot). Herbs, often somewhat succulent; Leaves simple, alternate or opposite, often fleshy (almost succulent); Flowers actinomorphic, polypetalous, Fruit capsule. 2 sepals and 5 petals, stamens 5-many and often opposite to petals, ovary superior with 2-3 fused carpels. note: Lewisia is an important exception with numerous (2-9) sepals and petals as well as stamens. BETALAINS present; Portulacaceae (Purslane family)

Herbs, shrubs, trees, or vines; Leaves simple, alternate; stipules present and connate into an often thin sheath (ocrea) around the stem. Flowers 3-parted, Tepals usually 6 (sometimes 5 due to fusion of 2 tepals), stamens 6-9, ovary superior with 2-3 fused carpels. Fruit nutlet or achene. BETALAINS present;
