ORDER CIII. SCROPIIULARINEJS. (By J. D. Hooker.) 



Herbs or shrubs, rarely trees. Leaves, all, or the lower only, opposite, rarely 

 all alternate or whorled ; stipules 0. Inflorescence centripetal or composite ; 

 flowers usually irregular. Calyx inferior, usually persistent, 5- rarely 4-merous. 

 Corolla hypogynous, 4-5-lobed. Stamens usually 4, with a rudimentary 5th, 

 rarely 2 or 5 ; anthers 1-2-celled, cells distinct, or more or less confluent. Disc 

 annular, glandular, or cup-shaped. Ovary 2-celled (very rarely 1 -celled) 

 (Lathreea) ; style simple ; stigma capitate, dilated, 2-lobed, or 2-lamellate ; ovules 

 many, rarely 2, in each cell, anatropous or amphitropous. Fruit capsular, 

 rarely baccate ; placentas on a free central axis, or remaining attached to the 

 margins of the valves. Seeds small, various in form, hilum lateral or ventral, 

 albumen fleshy (0 in Wightid) ; embryo straight or curved. DISTRIB. Species 

 about 2000, native of all regions. 



In this Order I have departed from the "Genera Plantarum" in introducing 

 Lathreea under the Tribe Euphrasiece, instead of retaining it in Orobanchece. This, 

 its proper position, was pointed out by Solms Laubach, in a dissertation which was 

 overlooked when the Scrophularineee of the " Genera " were elaborated. I have also 

 transferred Campbellia to Christisonia, which is left in Orobanchets till the living 

 plant shall be studied morphologically. 



A few non-Indian garden Scrophularinees are more or less frequent near stations, 

 but none seem truly naturalised to any extent except the American Calceolaria 

 mexicana, Benth., which is so about Darjeeling and in the Nilgherries.
