SCROPHULARINEJE 311 



glabrous, glaucous on both surfaces ; lamina 4-6*75 mm. long, 

 2*25-4 mm. wide ; petiole slightly channelled above, convex be- 

 neath, -5-1-75 mm. long. 



Stem herbaceous, erect, terete, glabrous, glaucous-green ; 1st 

 internode 4-7'5 mm. long ; 2nd shorter. First internode of branches 

 from the hypocotyl 1-1-5 cm. long. 



Leaves simple, entire, cauline, with the lower and primary ones 

 opposite or in. whorls of three to four, shortly petiolate, deeply 

 glaucous on both surfaces, glabrous, trinerved at the base with a 

 few alternate, ascending nerves upward, rather opaque, and best 

 observed by transmitted light ; petioles very short, tapering down- 

 wards, slightly channelled above, convex beneath. 



First and second pairs lanceolate-elliptic, obtusely pointed. 



First node on the branches bearing two, or on strong branches 

 three elliptic or lanceolate-elliptic obtusely pointed leaves. 



linaria reticulata, Desf. 



This species agrees with L. genistifolia in the horizontal 

 anatropous ovules and seeds, but differs in the latter being slightly 

 curved and transversely ribbed, not angled. The embryo is also 

 similar, but slightly curved in conformity with the seed. 



Capsules 3'5-4 mm. long, 3-3-25 mm. wide, 2'75-3'25 mm. 

 thick, containing one hundred and thirty-three to one hundred and 

 thirty- six seeds. 



Seeds -75 mm. long, -2S--5 mm. wide, but variable and thickest 

 at the end farther from the hilum. 



Linaria striata, DC. 



Hypocotyl as in L. genistifolia ; 1-2-2-7 cm. above the soil, 

 becoming early proliferous at the surface, and bearing three to five 

 or more branches soon exceeding it in length and strength. 



Cotyledons elliptic, obtuse, glabrous, glaucous-green and rather 

 opaque above, paler beneath, with the midrib only discernible ; 

 lamina 7 mm. long, 3'5-4 - 25 mm. wide in the middle ; petiole 

 channelled above, convex beneath, glabrous, 1-5-3 mm. long. 



Stem. 1st internode 1-1*3 cm. long; 2nd 1'65 cm.; 3rd 1- 

 1-2 cm. 



Leaves as in L. genistifolia. 



First pair elliptic, obtuse. 



Second pair narrower, lanceolate-elliptic or oblong-elliptic, obtuse. 



First, second and third whorls on the branches. similar to those on 

 the primary stern, and wide or narrow according to the strength of 

 the seedling.
