SOLAXACE.E 293 



Hypocotyl variable in length, 8 cm. or more, 1*5 mm. thick, 

 terete, coarsely pubescent or hairy. 



Cotyledons oblanceolate-liiiear, obtuse, entire, tapering towards 

 the broad clasping base, 3-3 cm. long, 3-4 mm. wide, hairy. 



Stem terete, coarsely hairy, about 1 rnm. thick when showing 

 two leaves above the cotyledons, but rapidly becoming much stouter ; 

 1st internode 8 mm. long ; 2nd almost suppressed, thus bringing 

 the first two leaves nearly, but not quite, opposite ; 3rd and 4th 

 gradually longer. 



Leaves cauline, alternate, exstipulate, petiolate, more or less 

 pinnatisect, coarsely hairy and glandular-rugose. 



No. 1. Unequal at the base, consisting of a large terminal 

 unequally trilobed segment, and a small, oval, entire, obtuse 

 lateral one. 



No. 2. More perfect ; terminal segment ovate, trilobed ; lobes 

 obtuse ; basal pair small, lanceolate. 



No. 3. Pinnately trisect ; terminal segment triangularly ovate, 

 shallowly trilobed, subcordate at the base ; lateral segments 

 narrowly ovate, obtuse, cordate at the base and falcately curved, 

 entire. 



No. 4. Pinnately four-sected ; the terminal and the lowermost 

 segments solitary. 



No. o. Pinnately five-sected ; basal pair of segments small, 

 ovate, entire, obtuse, cordate at the base ; middle pair ovate, elon- 

 gate, entire, obtuse, cordate at the base ; terminal segment ovate- 

 elongate, obtuse, shallowly lobed, somewhat twisted towards the 

 top. 



No. 6. Similar ; the two lateral pairs ovate, obtuse, entire, 

 unequallj subcordate at the base ; terminal one much larger, ovate, 

 elongated, obtuse, shallowly lobed and somewhat involute at the 

 margins longitudinally on the upper entire part ; petiole terete, stout, 

 furrowed somewhat on the upper side. 



Stem, leaves and petioles are covered with two kinds of hairs at 

 least in the younger state ; longer hairs coarse and non-glandular ; 

 shorter hairs fine and tipped with glands. 



Ultimate leaves irregularly and interruptedly pinnatisect ; seg- 

 ments stalked, not articulate (therefore not pinnate), obtuse or sub- 

 acute, opposite ; lowest pair usually small, ovate, entire ; second 

 pair oblong, ovate, pinnatifid or coarsely dentate ; third pair very 

 small, ovate, scarcely opposite ; fourth pair oblong-ovate, shallowly 

 lobed, very unequal at the base ; fifth pair very small, oval, alter- 

 nate ; terminal leaflet or segment oblong, pinnatifid. 



The adult leaves, moreover, are extremely variable in size in the
