165 This inhabits the same region as M, arborif orme , and may- 

 have been mistaken for that species, but the larger and denser cymes 

 of larger flowers readily distinguish it, and the leaves and bracts 

 also appeer to be more obtuse. From ^^5. tu^•eros^lm its rather smaller 

 and much more copious flov;ers at one distinguish it, their colour 

 is not indicated on the label. 



3. M, arborif orme, N.E.Bp. — Plant 9-18 Inches in height, 

 tree-like in hpbit, having; a definite trimk "up to one inch in 

 diameter," much and intricately branched. Main branches 1^-2^ 

 lines t'-'ick, with internodes 3-6 lines long, rough from minute pap- 

 ulae and pallid or whitish when young, becoming smooth and purple- 

 brown or blackish-brov/n with age. Leaves 1^-7 lines long, 4-I line 

 thick, subteretely trigonous, slightly compressed, obtuse and often 

 slightlyrecurved at the apex, microscopically papulose under a strong 

 lengs, green. i^'lo'A'ers very small, in terminal, dichotomous cymes 

 I4-3 inches in diameter. Pedicels i-l| line long. Calyx with the 

 overy-fprt shortly obconic and about 4-1 line in diameter; lobes 4- 



1 line long, deltoid, obtuse, some v.'ith membranous margins. Corolla 

 about 3-3| lines in diameter; petals 1-lt line long, i line long, 

 linear, obtuse, on the labels with the dried specimens stated to be 

 "pale orange," "orange- bronze, " and "yellov," Stamens about ^-2/3 

 line lone, white, v/ith the anthers lon^^er than the filaments. 

 Stigmas 4-1/3 line long, subulate. Tq^ of the ovary flattish-coni- 

 cal. Capsule 1-1§ line in diameter. ^11 other characters as for 

 the genus .

I do not know if this plant has a tuberous rootstock or not, 

 as no collector mentions it on the label with the specimen, nor has 

 Burchell made any note about it in his manuscript cataloge at ^w. 

 Pearson has labelled 8589 as being a "bush 1-3 ft.", so that the 

 Namaqualend plant may grow taller than it does in Griqualend ^I'est 

 and Prieska. But I can detect no difference between the specimens, 

 apart from size. 



4. M. elatum, N, E. Br. — A shrub 2-4 feet high, with the 

 main branches ascending, 2-3 lines t"ick below, with interenodes 5-12 

 lines long, when young very minutely papulose and pale greyish, 

 becoming smooth and brown with age, but in the dried state th bark 



is longitudinally vrrinkled. Leaves ascending-spreading in or 

 spreading, 4-7 lines lon^, 2/3-* line thick, compressed-trigonous, 

 flat or slightly chainelled dovm the face, keeled on the back, 

 recurved at the apex, which is dorsally shortly acute^or obtuse as 

 viewed sidev/ays, microscopically papulose. Cymes 1-1* inch in 

 diameter, densely 15-20-f lowered. Pedicels 1-3 lines long. Bracts 

 very small, about -^-f line long and apparently soon felling away. 

 Calyx with the shortly obconic ovrry-part li-l^ line in diameter; 

 lobes about f line long, deltoid, obtuse. Corolla 3-3| lines in 

 diameter; petas scarcely 1 line long, obtuse, "purple probably 

 of some shade of magenta. Stamens about 4 lin*^ long. Stigmas 

 scarcely 1/2 line lonr*. Capsule li-l^ line in diameter, soon falling
