Order LXXVIII. LENNOACEJ2. 



Root-parasitic leafless herbs, scaly and fleshy, with much the aspect of Mono- 

 tropece, but with stamens inserted in or near the throat of the tubular corolla, 

 and the polymerous ovary peculiar, the cells being at least double the number 

 of the other parts of the 5-10-merous regular and perfect flower, and uniovulate; 

 the fruit drupaceo-polycoccous. Sepals 5 to 10, linear or filiform. Corolla hypo- 

 gynous, tubular or slightly funnelform, marcescent, 5-8-lobed, the lobes plicate- 

 imbricated in the bud. Stamens as many as the corolla-lobes and alternate with 

 them: filaments very short: anthers 2-celled, introrse ; the cells opening longi- 

 tudinally: pollen simple, 3-sulcate. Disk none. Ovary depressed-globose, 12- 

 28-celled (doubtless of half as many 2-locellate carpels, surrounding a thick axis) : 

 style slender : stigma crenulate or somewhat lobed. Ovule horizontal, anatropons 

 or somewhat amphitropous ; the orifice superior. Fruit depressed-globular, with
