ORDER 36 CRASSUlACEJE. (ORPINE FAMILY.) 



Succulent herbs, with perfectly symmetrical flowers ; iriz., the petals and 

 pistils equalling the sepals in number (3 - 20), and the stamens the same or 

 double their number, technically different from Saxifrageae only in this 

 complete symmetry, and in the carpels (in most of the genera) being quite 

 distinct from each other. Also, instead of a perigynous disk, there are 

 usually little scales on the receptacle, one behind each carpel. Fruit dry 

 and dehiscent ; the pods (follicles) opening down the ventral suture, many- 

 rarely few-seeded. Stipules none. Flowers usually cymose, small. 

 Leaves mostly sessile, in Penthorum not at all fleshy. 



# Not succulent ; the carpels united, forming a 5-celled capsule. 



1. Penthorum. Sepals 5. Petals none. Stamens 10. Pod 5-beaked, many-seeded. 



* # Leaves, etc., thick and succulent. Carpels distinct. 



2. Tillsea. Sepals, petals, stamens, and pistils 3 or 4. Seeds few or many. 



3. Sedum. Sepals, petals, and pistils 4 or 5. Stamens 8 - 10. Seeds many. 



1. PENTHORUM, Gronov. DITCH STONE-CROP. 



Sepals 5. Petals rare, if any. Stamens 10. Pistils 5, united below, forming 

 a 5-angled, 5-horned, and 5-celled capsule, which opens by the falling off of the 

 beaks, many-seeded. Upright weed-like perennials (not fleshy like the rest of 

 the family), with scattered leaves, and yellowish-green flowers loosely spiked 

 along the upper side of the naked branches of the cyme. (Name from Wire. 

 five, and opos, a mark, from the quinary order of the flower.) 



1. P. sedoides, L. Leaves lanceolate, acute at both ends. Open wet 

 places, N. Brunswick to Fla., west to Minn., E. Kan., and Tex. July -Get 

 Parts of the flower rarely in sixes or sevens.
