Cephalanthus spathellifeeus, n. sp. — A very large tree, with 

 subglabrous stoutish branclilets. Leaves in wliorls of 4, shortly 

 petioled, lanceolate, 5-6 in. long, 1-1 i in. broad, acute, coria- 

 ceous, green and glabrous on both surfaces ; stipules small, 

 deltoid, connate, deciduous. Flowers in globose heads above 1 in. 

 diam., on erecto-patent axillary peduncles 2-3 in. long, enveloped 

 in a young stage in a deciduous deltoid-cuspidate scariose brown 

 bract ; bracteoles silky, spoon-shaped at the tip, as long as the 

 calyx. Calyx ^ in. long, silky ; tube angled by pressure ; teeth 5, 

 deltoid, erect. Corolla with a cylindiical tube ^ in. long, and 

 5 oblanceolate-oblong patent segments as long as the tube. Stamens 

 5, nearly sessile at the throat of the corolla- tube. Style nearly 

 twice as long as the corolla ; stigma capitate. Fruit not seen. —

 veining ; stipules connate, deltoid, deciduous. Flowers in lax 

 sessile or nearly sessile corymbs in the axils of the leaves, which 

 are cernuous in an early stage ; bracts minute, lanceolate, or 

 deltoid ; pedicels as long or longer than the calyx, glabrous. Calyx-
