umbels in fruit become apparently capitate. The number of segments of the 

 enormous leaves were counted in the field, while the measurements given 

 for the length of the leaves include 1'2 dm. of the peduncle, which does not, 

 however, represent its entire length. Calyx 3 mm. long. Disc and styles 

 '7 mm. long. Fruit 4 mm. by 4 mm., semi-superior, with disc and styles 

 1 mm. long. Seeds laterally compressed, +3 mm. long. 



This plant comes into Eusliefflera on the strength of the pedicellate 

 flowers, but the capitate heads of sessile fruit suggest Cephaloshefflera. 

 In the pseudo-involucre of minute scales becoming longer in fruit, it seems 

 distinct from either section. It belongs to the Heptapleurum group, in 

 which the styles are joined in a short thick column.

A small tree with large deltoid leaves aggregated towards the top, the 

 inflorescences arising in the axils of the upper leaves ; in dried condition 

 the wine-brown colour of the stems and rhachis of both leaves and inflor- 

 escence is very characteristic. The petiole is 1*7 dm. long, dilated at the 

 point of insertion, but contracted just above it, while the leaf is 3'3 dm. by 

 (5 dm. at the base, with the lowest pinnae 5-jugate and the upper 3-jugate, 

 the largest folioles being 8'5 cm. by 3*6 cm., with petiolules 1'3 cm. long. 

 The inflorescence (immature) is 4'5 dm. by 5'2 dm., with peduncle + 12'5 dm. 

 long. The secondary and tertiary branches are either opposite or verticillate, 

 this arrangement being alternate to a certain extent ; the secondary branches 

 are terminated by one umbel (in specimen) of mature flowers, which is sub- 

 tended by a whorl of tertiary umbels on much longer peduncles, interspersed 

 with single pedicellate flowers, all the umbels being surrounded by involucres 

 of small linear bracts ; the tertiary peduncles are + 4-5 cm. long (very yg.) 

 and bear bracts with, in some cases, single flower-buds in their axils at ^-| 

 of their length. All the young parts are covered with a rusty tomentum. 

 Petals 2*3 mm. by 1'4 mm. Stamens short and erect, with anthers 1/2 mm. 

 with median insertion, and filaments 1 mm. long. Ovary 2*4 mm. by 1'3 mm. 

 with 1 ovule in each loculus. Style 1 mm. in length. 



This plant differs from the monotypic Kissodendron australiensis (JT. 

 Muell.) Seem, in the bipinnate leaves, the ovate-lanceolate shape of the
