CLERODENDRON sacrosipnoy, 
Native of Zanzibar. 
Nat. Ord. VerBenacem.—Tribe Vit1cEx. 
Genus CLERopENDRON, Linn.; (Benth. et Hook. SF. Gen. Pl. vol. ii. p. 1155.) 
CLERODENDRON (Cyclonema) macrosiphon; ramis gracilibus foliisque puberulis, 
foliis petiolatis oblanceolatis v. elliptico-lanceolatis grosse inequaliter dentatis 
in petiolum longe angustatis, floribus in cymam brevissimam terminalem 
subsessilem confertis, pedicellis brevissimis, calyce parvo dentibus ovatis acutis, 
corolla alba tubo 3-4-pollicari gracillimo piloso, limbi 1-poll. lati unilateralis 
lobis secundis ovato-oblongis subacutis, filamentis 2-pollicaribus antherisque 
parvis purpureis. 
A very elegant shrub, one of the many discoveries of Sir 
John Kirk, who sent living plants of it to Kew in 1881, 
which flowered in May of the following year in the stove. 
The corolla, which is pale green in bud, becomes when 
expanded snowy white, relieved by the long purple threads 
of the filaments. Most of the species which possess a 
corolla-tube approaching this in length, belong to the 
Section of the genus with a more regular limb of the corolla, 
as, for example, C. hastatwm, Wall., of India (Plate 3398), 
of which the corolla-tube is even longer. There is, how- 
ever, described in the botanical part of “ Peter’s Reise nach 
Mossambique” (p. 259) a O. incisum, Klotzsch, from the 
Sana river in East Africa, which approaches C. macrosiphon 
" very closely, differing, according to the description, chiefly 
In the glabrous calyx and corolla. This latter has a 
Similar corolla, and it is probable that the species in which 
the lobes all point one way should form a distinct section 
of the genus. Only one other species with this structure 
has been previously figured in this Magazine, namely, C. 
macrophyllum, Sims (Plate 2536). 
Sir John Kirk found C. macrosiphon on the coast oppo- 
site Zanzibar Island, in very rocky places, where it formed 
a small slender shrub.
