Hawaii: Woods of Hilo, leg. Lydgate, in herb. Berlin, part of type 
in herb. College of Hawaii, no. 13065. This variety was not collected 
by the writer. 
Cyrtandra platyphylla robusta Rock n. var. 
Plant stout, robust, the stems strongly quadrangular and of 
almost even thickness to the apex, densely villous-hirsute, with dark 
reddish-brown hairs; leaves ovate-oblong, acute or acuminate, with 
denticulate margins, covered with multicellular hairs on the upper 
surface, densely villous- tomentose beneath, as are the petioles; pe- 
duncle about 3 cm. long; pedicels 1.5-2.5 cm. long, three-flowered, 
densely villous as are the obovate, acute bracts and calyx, the latter 
subequally divided to beyond the middle into oblong acuminate lobes, 
which are hirsute on both sides; corolla slightly protruding, the small 
rounded lobes glabrous on both sides, with the exception of the margin 
which is slightly ciliate, the tube hirsute nearly to the base, but more 
so in the upper part; ovary glabrous; style hirtulose with scattered 
multicellular hairs.

This variety, which has the hirtulose style in common with var. 
stylopuhens of the same species, difl^ers from that variety in the very 
stout quadrangular stems, dense villosity, longer peduncles, more 
robust inflorescence, and in the thick calyx lobes which are densely 
hirsute on both sides.

The writer is not acquainted with this plant, nor has he seen the 
type. When the type will have been examined it will undoubtedly 
prove to be only a variety of Cyrtandra platyphylla. Clarke's descrip- 
tion may answer any of the forms of that species, as for example 
''folia opposita, pedunculi saepe oppositi,'' etc. ; there is nothing definite 
in the description whereby it could readily be distinguished from 
Cyrtandra platyphylla. In conclusion he states: ''species C. Picker- 
ingii forsan affinior, ah hac divert {inter alia) ovario haccaque glabris''; 
this however is one of the main differences between C. Pickeringii and 
C. platyphylla. It is true that the former has broadly triangular 
calyx-lobes, but those of the latter species are exceedingly variable, 
and calycine lobes as described by C. B. Clarke in C. baccifera, ''late 
lanceolati," occur certainly in C. platyphylla.
