MACLOSKIE: ANALYSIS OF ORDERS AND FAMILIES. 911 



e2. (Santalales.) Perianth green or petaloid. Stamens as many as the perianth- 

 segments, or twice as many. Ovary i -celled, superior or inferior; seeds 

 few, often imbedded in the placenta ; with large endosperm. Plants usually 

 more or less parasitical. 

 /. Leaves green, estipulate. Seed solitary. 



g. Leaves mostly opposite. Flowers monoecious or dioecious. Ovary 

 l-celled, i -ovuled, immersed ; fruit a berry. Parasitic shrubs. 



Family 26. Loranthacea, Mistletoe, p. 335. 



g2. Leaves alternate or opposite. Flowers hermaphrodite. Calyx 4-5- 

 cleft, its tube adnate to the I -celled ovary. Ovules 2-5. Style 

 cylindric. Semi-parasitic. 



Family 28. Santalacecz, Sandalwood, p. 338. 



/2. Leafy or leafless. Flowers dioecious ; the males naked, 2-3-staminate ; 



the females with 3 -parted calyx, adnate to the 3 -seeded ovary. Fruit i- 



seeded, trigonal, with 3 feathery plumes on the angles. Tree -parasites. 



Family 27. Myzodcndracea, Angel's beard, p. 336. 



/3. Leafless, fungus-like parasites, only the top of the large solitary flower 

 visible above ground. Stamens 3 (5), with 3 staminodes. Ovary in- 

 ferior ; fruit baccate. Family -30. Hydnoracece, p. 344. 

 d^. Perianth double, the calyx minute, or none. Trees or shrubs with alternate, 

 estipulate leaves, and perfect flowers. Stamens i-3-seriate. Ovary 4-celled ; 

 the cells i -seeded. Fruit a drupe. Family 29. Olacacece, p. 344. 

 d$. (Polygonales?) Flowers cyclic or subspiral, radiate, with a 3-merous tendency. 

 Ovary i -celled, with i, mostly orthotropous, ovule. Flowers usually small, in 

 compound inflorescences. Leaves mostly with an ochrea. 



Family 31. Polygonacece, Buckwheat, p. 345. 



CC. Subclass CHORIPETAL^E or Mesochlamydeae. Flowers mostly hermaphrodite, the 

 perianth usually sepalo-petalous (i.e., differentiated into calyx and corolla); the 

 leaves of the corolla being distinct petals and usually colored. In a few genera 

 the petals are wanting, and then the sepals are petaloid. 



(Families 32-82), p. 354-643. 



d. Alliances with single bracteoid or petaloid perianth ; yet often sepalo-petalous. 

 c. (Centrosper males?) Flowers spiral or cyclic, small and crowded, tepalous or 

 sepalo-petalous, hypogynous. Stamens often isomerous with, and opposite 

 to the perianth-leaves, yet varying from many to I. Carpels I to many, 

 mostly syncarpous. Ovary rarely pluri-celled, mostly i -celled, with i-oo- 

 curved seeds. Embryo mostly curved around endosperm. Chiefly herbs. 

 f. Tepalous, bract-like, perianth. 



g. Flowers greenish ; bracts, if any, not scarious. Styles 1-2. Utricle 

 rarely circumscissile, mostly indehiscent. 



Family 32. Chenopodiacea:, Goosefoot, p. 354. 



g2. Flowers green or white, with scarious bracts and 2 bractlets. Utricles 

 mostly circumscissile. Family 33. Amarantacece, Amaranth, p. 372. 

 /2. Petalous, symphyllous perianth, usually with a calyx-like involucre. 

 Style i ; fruit an anthocarp. 



Family 34. Nyctaginacca, Marvel of Peru, p. 376.
