Hallier f." calls attention to the fact that Convolvulus hirtus L. is the same 
as Merremia caespitosa (Roxb.) Hailier f., after an examination of the 
specimen in the Linnean herbarium. Dr. C. B. Robinson has kindly 
examined the Linnean material, and writes that there are two specimens in 
the Linnean Herbarium under Convolvulus hirtus, the first named by 
Linnaeus, the second not named, but under it Linnaeus has written "Ind."; 
this second specimen is the slender-leaved, glabrous form which has been 
described as Ipomoea philippinensis Choisy, and Dr. Robinson states that it 
might well have been a part of the specimen which Linnaeus named Con- 
volvulus reptans (see above under Ipomoea reptans Poir.). However, it is 
the first specimen that Linnaeus described, and as he wrote the name on it 
only, it must be the type. Dr. Robinson states that Linnaeus' description 
is excellent, the specimen having much broader leaves than the second one, 
ovate to suborbicular, the inflorescence more developed, and the stems 
hirsute with spreading hairs. It is possible that more than one species is 
represented in what Haliier would call Merremia caespitosa and that the 
narrow leaved, glabrous form should be separated from the broad leaved 
form with hirsute stems. The evidence from specimens in this herbarium, 
however, seems to indicate that intergrades occur; for instance, some 
specimens are glabrous or nearly so, with linear leaves and 1- or 2-flowered 
peduncles; some have linear leaves, hirsute stems, and several-flowered 
peduncles; some have leaves varying from linear to oblong or oblong-ovate, 
with the base varying from acute to hastate; and some have mostly ovate 
leaves. None of the Philippine specimens agree with Linnaeus' description 
as to leaves "cordato-subrotunda," and none of our broader leaved forms 
have hirsute stems.

Clerodendron inerme Auct. Philip., non Gaertn. 
This species is common and widely distributed in the Philippines along 
the seashore, and is enumerated here simply to call attention to the oldest 
specific name, provided the species is distinct from Clerodendron inerme 
Gaertn., as Clarke and Gamble have considered it. Poiret*s description 
most certainly applies to this form, although Clerodendron commersonii 
was considered by Schauer among the "species dubiae." 
Gamble gives the range of Clerodendron neriifolium Walt. (C. com- 
mersonii Spreng.), as from the Malay Peninsula and Burma to the Phil- 
ippines, China, Australia, and Polynesia. In addition to the very extensive 
series of Philippine specimens in this herbarium, we have also the following:
