blue rather longer, sliglitly hairy 6. Z. anmui. 



Calyx-lobes about a line long ; corolla-lobes yellowish ■ 



violet about as long 7- Zr. arenaria. 



Calyx-lobes less than \ line long ; corolla-lobes deep 



blue 3 or 4 times as long, glabrous 8. i. gracilis. 



Calyx-lobes as in the last, but bristly at the^ tips ; 



corolla-lobfs cohering after flowering as in Wahlen- 



bergia, yellow and blue 'd. L. exilis.

corolla 3' or 4 times as long 11. L. faniculata.

1. Xe. xnarg-inata, A. DC. in Ann. Sc.Nat. ser. 5, vi. p. 326. Suffru- 

 tescent with woody ascending pilose stems 8-18 in. high, naked at the 

 base. Leaves alternate sessile oblong or lanceolate acute, 2-12 lines 

 long, passing gradually into bracts, glabrous or sparsely pilose, with a 

 few callous teeth ; margin of the leaves bracts and calyx-lobes white 

 with distant callosities. Inflorescence loosely subspicate ; flowers 1-3 

 in the axils of the bracts, which equal the flowers, on pedicels 1-2 lines 

 long. Calyx-tube obconical pilose; lobes lanceolate entire. Corolla 

 divided almost to the base, pale blue lj-l| lines long. Capsule 

 obconical, free in the upper part. — Description chiefly from De 

 Candolle.*

2. Xi. abyssinica, Bochst. in Rich. Fl. Abyss, ii. p. 1. An erect 

 branching half shrubby perennial, 1^2 ft. high, young parts glabrous 

 puberulous or almost hispidly pilose, according to the nature of the 

 habitat in which the plant grows. Branches slender hard and woody. 

 Leaves alternate sessile lanceolate or linear-lanceolate acute cartila- 

 ginous on the margin entire or with a few distant callous teeth, some- 

 what hard and coriaceous, 1 J-3 in. long ; midrib prominent, secondary 

 nerves inconspicuous. Flowers small in narrow cymose branched 

 panicles a foot or more in length ; bracts minute ; pedicels 3-6 lines 

 long, elongating in fruit. Calyx glabrous ; lobes equalling the hemi- 

 spherical tube. Petals about 3 lines long, narrow, finally twisted. 

 Capsule subglobose, prominently 5-ribbed.

 The Abyssinian specimens are much more hirsute than the southern ones, but 

 there appears to be no other difference, and this is only one of degree. 



* After drawing up the descriptions from De Candolle, I.e. I had an opportunity 

 of seeing a set of Wolwitsch's specimens at the British Museum, and found it neces- 

 sary to make some considerable alterations in the dimensions, etc.
