THE FLORA OJ THE NORTHEEN TERRITORY. 265 



Section II. Amphichila. — Corolla with the 2 upper lobes separated much 

 lower down than the others. Ovules very numerous, closely packed in more 

 than 2 rows in each cell of the ovary. Flowers small, in leafless panicles or on 

 radical scapes. 



Flowering stems | to 2 ft. high, several times longer than the radical leaves. 

 Flowers purple. — 15. G. purpurascens.

Panicle loose and moderately branched. Leaves not con- 

 spicuously veined. — 8. G. gracilis. 

 Panicle very much branched. Leaves rigid, conspicuously 

 veined. — 12. G. lamprosperma. 

 Flowering stems 2 to 4 in. high, much exceeding the tufted or rosulate 

 membranous radical leaves. — 4. G. bicolor. 



Dwarf creeping or stoloniferous plant. Leaves ovate, in rosulate tufts. 

 Scapes or peduncles filiform, mostly 1-flowered. — 14. G. pumilio.

6. G. erecta, Ewart (Plate XXII.). — Calyx-segments subulate, connate in 

 lower half with tube of corolla, which is yellow, with upper lobes separated 

 half-way to base and unequally winged, capsule cylindrical with dissepiment 

 reaching to near top, seeds minute, numerous in 2 rows. Inflorescence in 

 long narrow racemose panicles. 



Lower stem-leaves absent, that subtendiag lowest peduncles of inflores- 

 cence 2 cm. long, obovate acute with a few large teeth, sinuate-toothed tapering 

 gradually to base and almost decurrent in a thin line, floral leaves above less 

 toothed and diminishing to linear bracts. Inflorescence a narrow racemose 

 panicle up to 3.8 cm. in length. Peduncles in axils of stem leaves and shorter 

 than these, bearing cymes of 3-7 flowers with a pair of leafy bracts at forks, 

 Calyx 5-6 mm. long, subulate free part of segments as long as connate, tipped 

 with minute dark coloured glands, seen also on bracts. Corolla yellow, thinly 

 pubescent externally, 12 to 14 mm. in length, upper part cleft for half-way to 

 base with a shorter wing on lower margin, forming a linear gibbosity between 

 segments of calyx on under side of tube formed by coalescence of calyx, coroUa, 

 and ovary. Summit of ovary 3 mm. in flowering stage, free and glabrous, 

 style of a deep blackish violet, with long cilia from near the base to indusium, 

 which is glabrous on back with short white or sometimes purplish cUia on 

 piargin. Capsule cyhndrical, 6 mm. long, with dissepiment to near top, 

 seeds numerous in 2 rows, flat suborbicular minutely granular and .surrounded 

 with a narrow smooth margin. 



The plant shows a general agreement with the characters of G. scaevolina, 

 F. v. M., although this is not seen in the leafy young specimens representing
