330 WILSON EXPEDITION TO CHINA 
mm. longis glabris, antheris luteis sagittatis; pistillum staminibus 
brevius, ovario leviter compresso glabro v. sparse pubescente, stylo 
crasso, stigmate simplice. Capsula subglobosa, compressa, 6-8 
mm. alta, leviter verruculosa, stylo persistente coronata 2-valvis, 4- 
sperma. 
Western Szech’uan: near Mao-chou, valley of Min River, alt. 
1300-1800 m., May 26, 1908 (No. 3182, type; flowers); same locality, 
alt. 1000 m., August 1904 (Veitch Exped. No. 3230; co-type fruit). 
This new species is most closely related to P heterophyllum Franchet, which is 
distinguished by its thinner, heteromorphic and larger leaves. It may also be com- 
pared with P. humile Hooker f. & Thomson, which has larger leaves, a racemose 
sub-umbellate inflorescence, shorter pedicels with longer bracts, and smaller flowers 
with sepals half as long as the corolla. P. saxicola is common in rocky places in 
arid parts of the valley of the Min River. Often it forms low scrub with stems 
prostrate on the ground, but under favorable conditions it is a bush 2 m. high and 
as much through. We are not sure that the fruit always contains four seeds only. 
Here may be added a note on a species from Formosa. 
Pittosporum formosanum Hayata in Jour. Coll. Sci. Tokyo, XXII. 32, t. 4 
(Enum Pl. Formosan.) (1906); in XXX. art. 1, 34 (1911). 
Pittosporum sp. nova Henry in Trans. Asiat. Soc. Japan, XXIV. Suppl. 18 
(List Pl. Formosa) (1896). 
Formosa: Takow, Ape’s Hill, A. Henry (Nos. 1058, 1070*, 1888; shrub or 
small tree 1-3 m. high); same locality, G. M. Playfair (No. 52); Bankinsing, A. 
Henry (Nos. 48, 822); South Cape, A. Henry (Nos. 256, 971, 977). 
We do not think that this species has any affinity with P. pauciflorum Hooker 
: M stated by Hayata. Tous it appears most closely related to P. Fernan- 
ezii Vidal.
