1. PROTEA MADIENSIS, Oliv., sp. nov. Arborescens ; foliis semipedalibus lanceolato- 
ellipticis, utrinque angustatis, obtusiusculis, breviter petiolatis, pilis subappressis sparsis

marginatus, 2-2 poll. longus. Capitulum 8-4 poll. diam. ; squamæ exteriores minores, late ovato-rotun- 
datz, intermediæ late ovato-ellipticæ, obtusissimæ, glabrate v. basin versus puberulo-tomentosæ, indu- 
mento deciduo, interiores longiores, 24 poll. longe, oblongæ v. oblongo-lanceolatæ, obtuse, dorso 
apicem versus glabro, alabastris longiores. Perianthium dense villosum, apicem versus glabrum v. 
sparse pilosum. 
Hab. Madi, Dec. 1862 (Protea, sp., App. Speke's Journ. 645), Col. Grant! 
Nearly allied to P. abyssinica, W., differing in the form of the leaves, and glabrate involucral scales 
and perianth-tips. 
[This shrubby tree was not observed on our route till we arrived at Madi, in December, when it was in 
full bloom in the forest. Тһе people make some use of its wood ; for the trunk of one had been eut down— 
one of 20 inches circumference ; there grew from it several erect branches, 10 feet high. Тһе bark was 
finely striated, cut red, and showed a white cellular wood beneath. Leaves 8 by 4 inches, elongated 
to points, pale, with dull surfaces; they grow obliquely to the stem, and have waved transparent edges. 
Each flower-head opened flat out towards the sun, and was the size of alarge sunflower. Тһе scales of 
the flower increase as they reach the outer circle, where they are pink, linear, and 3 inches in length ; 
the flower is yellow, like а silvery sunflower. Native names “© m'zaza" and “ king-geezee " (Keeao). 
Boys while herding cattle wear wreaths of its flowers; the Wangamezi boil its leaves and eat them during 
famines. Black ants are attracted to the trees. I was told that copal-gum will always be found where 
this tree or shrub is abundant. Its wood makes a brilliant fire. No other uses were heard of.—

1. GNIDIA INVOLUCRATA, Steud.; DC. Prod. xiv. 589. Var. apiculata. Tripedalis, 
glabra; cauleerecto superne ramoso, ramis gracilibus ascendentibus ; foliis anguste ovali- 
linearibus, utrinque angustatis, acutissimis, planis; capitulis pedunculatis ; involucri 
foliolis membranaceo-scariosis, fuscis, glabris, ovatis, apiculatis. 
Folia 1-3 poll. longa. Capitula 4-4 poll. diam., breviter v. longiuscule pedunculata, pedunculis 
bracteatis ; squamæ interiores involucri apiculate v. breviter acuminate, 1 poll. longa. 
- Hab. Bare heights of Madi, Dec. 1862, Col. Grant ! 
This plant differs from the Abyssinian form in its pointed involucral scales. ]t may prove a distinct 
species, Тһе flowers are far advanced, the upper part of the perianth-tube being detached in Col. 
Grant's specimens. The figure of the flower in the accompanying Plate is, I believe, taken from an 
Abyssinian specimen. 58 2
