Frequent in mixed mallee shrubland on medium sandy soils from Fitzgerald River to 
Israelite Bay and probably east of there, usually near the coast, but not on coastal 
formations (Fig. 12). 
Conservation status: not considered to be at risk.

11B. Eucalyptus leptocalyx Blakely subsp. petilipes L.A.S. Johnson & K.D. Hill, subsp. nov. 
Ab subspecie leptocalyce fructibus minoribus et ovideis, pedunculi pedicellique longi 
tenuesque, et foliis alabastrisque aliquanto minora distinguitur. 
Type: Western Australia: 5 km NW of Coolinup Road on Kau Rock Road, NE of 
Esperanee (33°34'S, 122°25'E), M.l.H. Brooker 7548 ,12 Aug 1982 (holo NSW; iso CANB, 
PERTH). 
Mallee to 6 m tall. Adult leaves 6.0-12.0 cm long, 1.0-2.0 cm wide; petioles terete, 
1.5-3.0 cm long. Umbellasters axillary, 7-flowered. Peduncles terete to slightly 
flattened, 6-11 mm long. Pedicels 2—4 mm long. Mature buds 7-9 mm long, 4-5 mm 
diam.; calyptra faintly ribbed. Fruits 6-9 mm long, 5-8 mm diam. (Fig. 14). 
Subsp. petilipes differs from subsp. leptocalyx in the smaller, ovoid fruits with long, 
slender pedicels and peduncles, and the generally smaller leaves and buds. 
This subspecies occurs on light soils on slightly elevated sites, in mixed mallee 
shrubland, frequently associated with E. uncinata Turcz. and £. indurata Brooker & 
Hopper. To date, it is known from a small area north east of Esperanee and slightly 
inland (Fig. 12). This region is poorly explored, and extensions of range are probable. 
Intermediate populations between E. leptocalyx and E. scyphocalyx occur north of 
Esperanee (around Salmon Gums). Although intermediate in most characters, these 
populations are often much coarser in foliage characters than either parent. These are 
stable breeding populations with their own unique genetic makeup developed from a 
mixing of the parent species. 
Conservation status: not considered to be at risk. 
The epithet is from the Latin petilis, slender, and pes, foot, from the slender pedicel.
