DOBERA ALLENII, JN. £. Brown. 
SALVADORACEAE. 
. Allenii, V. £. Brown in Kew Bull. 1914, p. 80; affinis D. loranthi- 
foliae, sed foliis latioribus, petalis obtusioribus, tubo stamineo sub- 
_duplo breviore apice inter filamenta dentato, antheris haud apiculatis 
et stylo duplo longiore differt. 
Arbor magna, cortice ramorum cinereo. Folia opposita, glabra ; 
petiolus 5-8 mm. longus; lamina 4:5-7°5 cm. longa, 2-245 cm. 
minutissime tomentosus. Petala 4, erecta, 3 mm. longa, 15 mm. 
lata, elliptica vel lanceolata, subacuta, glabra. Glandulae disci 4, 
magnae. Tubus stamineus 
Troprcat Bast Arrica: Portuguese East Africa ; Antari, Allen, 95. 
The small genus Dobera, although undoubtedly allied to Salvadora, 
shows some affinity with the genera Aptandra and Ongokea in Olacineae, 
agreeing with those genera in its free petals, stamens united into a 
tube, and the four large glands outside the staminal tube, but differin, 
in its opposite leaves, tubular calyx, anthers and ovulation. Speci- 
fically D. Allenii is very similar to D. loranthifolia, Warb. and might 
be mistaken for it, but when the flowers are examined it is at once 
Fic. 1, flower; 2, flower with part of the calyx and two petals removed, 
showing the staminal tube and two of the glands outside it; 3, staminal tube, 
laid open; 4, anthers; 5, longitudinal section of the ovary. All enlarged.
